No one pays attention to ventilation if it functions properly. As a rule, exhaust vents are installed in the kitchen, bathroom and toilet. Air flows arise due to the difference in temperature inside the building and outside. At the same time, an influx of fresh air is necessary to ventilate the premises.
In the event of a malfunction, ventilation must be checked.
Kitchen
Cooking is carried out in this room and products of gas combustion and specific odors constantly appear. If a malfunction occurs in the hood, they spread to all rooms and remain there for a long time. In addition, the soot generated from the combustion of gas will be deposited on all surfaces. Most of it remains in the kitchen.
Bathroom
Violation of ventilation in the bathroom leads to an increase in humidity. At the same time, in the corners, on the walls and ceiling, dark spots mold, which is harmful to health.
High humidity is immediately felt by a person, and in this case, a ventilation check is necessary.
Toilet
If the hood in the toilet is clogged, being in it becomes unpleasant, and the smells from the bathrooms will spread throughout all the rooms of the apartment.
How to check for traction in a simple way
Ventilation is checked periodically as soon as dust appears on the grilles. To do this, they are removed and washed from dirt. After the lattice is installed back and the transom or window is opened slightly in the kitchen or in the room nearby. If the test is carried out in the bathroom or toilet, leave open doors to create airflow. To check the effectiveness of the hood, a sheet of paper is applied to it. He should "pull" to her, which is a signal of the presence of traction. Piece toilet paper must be held on the grate by itself. In another way, you can check for thrust by deflecting the flame of a lighter or candle. The procedure is repeated in all areas. Ventilation cleaning is required if the sheet is not attracted to the grate.
You need to know that in hot weather the draft in the ventilation duct deteriorates and it is useless to check it. It depends on the temperature difference between the room and the outside. In this case, forced ventilation is activated.
How to properly organize ventilation in the apartment
The lack of fresh air in the apartment can also be the reason for its poor circulation. This became especially noticeable with the replacement of windows with plastic ones, which are distinguished by their tightness. In this case, residents need to resolve this issue on their own. Ventilation is improved as follows:
- frequent ventilation of the premises;
- Installation of air conditioner;
- the use of supply valves;
- application of supply and exhaust forced ventilation.
The reason for the lack of traction may be residents living upstairs, or when the system is overloaded from an enterprise built on the ground floor, such as a store or cafe. Here, even a ventilation check is required, since extraneous odors appear in the apartment. In both cases, you need to seek help from the housing office.
Rules for cleaning ventilation ducts
Do-it-yourself cleaning of ventilation is prohibited, since the mine is serviced by specialists management company on the roof or technical floors. She is usually approached with complaints about the lack of traction. When calling specialists, you should warn your neighbors about this, since when cleaning the mine, dust can fall into the apartments through the ventilation openings.
When is produced self check ventilation, it is only allowed to clean the channel leading from the apartment to the main shaft. To do this, perform the following operations.
- Move furniture, cover the floor and close the wall in the work area.
- Remove, clean and, if necessary, replace the grate.
- Wearing gloves on your hands, carefully remove the debris from the ventilation duct and remove the residue with a vacuum cleaner. It is better to remove debris with a tool such as a spatula so as not to get hurt by sharp fragments.
- Install the grille back and check for draft by opening the window.
Additional ventilation device
When the ventilation of the house is working properly, but there is not enough fresh air, the following measures are required to improve the microclimate.
- Plastic windows are airtight, but it is advisable to purchase window systems with micro ventilation function.
- The supply of fresh air can be ensured with the help of valves, gratings, filters, heaters and supply forced fans.
- Partially help out the air conditioner, refreshing and drying the air.
- Install
When choosing a way to ventilate rooms, you should determine its effectiveness and which devices are already working. Must be checked first exhaust ventilation and identified the need to install additional equipment that improves the quality of its work.
No matter how efficiently the hood works, fresh air is needed. To do this, valves are installed behind the batteries. The diameter of the holes facing the street is 6-10 cm. A plug is installed in them, which can have a manual or automatic control. The incoming air can be cleaned using filter elements installed in the valves.
Ventilation is classified according to the following criteria:
- forced or natural movement of air in the premises;
- exhaust or supply type of device;
- what kind of service is provided: local or general house;
- the presence of channels for air transmission;
- type-setting or monoblock design.
The choice depends on the area and purpose of the premises, the number of equipment and people in it, and the type of their activity. In all cases, natural exhaust is preferred as it is the most economical option.
How ventilation systems are checked
Ventilation systems are subject to inspection, which can be emergency or scheduled. Checking their work is done using an anemometer. It is introduced into the ventilation duct, while ensuring the flow of air into the room.
In the branches of the mine, the air velocity must be at least 3 m/s.
The measurement results must be recorded.
They are recorded by devices, and then an act of checking ventilation is drawn up. It should provide data on how efficiently the system is performing and whether it meets design standards.
Conclusion
Checking the ventilation in an apartment is a simple operation that must be done in order to maintain an optimal microclimate.
In case of violations in its work, you need to know what the owner of the home can do and in what cases he should contact the management company.

Residents of apartments rarely remember about normally working ventilation. But if windows begin to fog up in the rooms, the smell of dishes being prepared in the kitchen spreads freely throughout the apartment, water constantly appears on the walls in the bathroom, the air is stuffy and stuffy, then the ventilation system has stopped working normally. In order not to risk the health of people living in the apartment, the condition of furniture and other interior items, it is better to eliminate the causes of these problems as quickly as possible. This may require cleaning.
Checking the operation of the ventilation system
Before proceeding with active actions, you should check how the ventilation in the house works. Doing it yourself is not at all difficult.
On the forums, it is advised to check with the flame of a burning match or lighter. With a normally operating hood, the flame should deviate towards the ventilation grille. Many people remember similar pictures from Soviet times, calling to check the draft in the gas column and the hood in the kitchen.
Representatives of utilities, especially gas workers, strongly oppose the method of checking the operation of ventilation in an apartment with a lighter. IN residential buildings with main gas pipelines, gas leaks are quite possible, which should just be pulled into a common ventilation pipe. In this case, you can provoke an explosion combustible mixture, which will lead to the most unfortunate consequences. Therefore, it is recommended to do the check in a safer way.
Similarly, you need to do with all the ventilation grilles to get the full picture. In most apartments, they must be in the kitchen, bathroom or bathroom.
Causes of clogged ventilation
The most common problem leading to malfunctions in the ventilation system is clogging of the channels that conduct air. Most often this happens due to the long-term accumulation of fat, soot and dust inside them, because most of the residents apartment buildings are limited to wiping the outer part of the gratings.
In old houses brickwork air ducts are destroyed under the influence of time and water getting inside, seeping from above or evaporating from the bathroom, and brick fragments can fill up the ventilation shaft, interfering with air exchange. There are frequent cases when unscrupulous tenants, wanting to improve their apartment and expand their living space, destroy the ledge in which the ventilation shaft passes, blocking the access of air to the apartments of the other inhabitants of the house. Uninvited tenants also contribute to blockages in ventilation: birds or wasps.
Residents of multi-apartment residential buildings should remember that representatives of special services should be involved in cleaning the main air duct. So if the ventilation does not work due to clogging, you should contact the management company that services the house. The maximum that residents can do on their own is to clean the ventilation ducts leading from the apartment to the common duct.
How to clean ventilation
After checking each hood in the kitchen, bathroom and rooms, it will become clear which channels are clogged. If ventilation does not work in all rooms, most likely the problem is in the common channel and nothing can be done on your own, if only in one - there is a local blockage that can be eliminated. For this you need:
- Remove the decorative grille and clean it of accumulated deposits. In this case, it is quite possible to use neutral detergents.
- Carefully remove dust, dirt and soot from the walls of the ventilation duct with a scraper, and then pull it out with a vacuum cleaner.
When cleaning, do not use aggressive chemicals that can corrode and damage the walls of the shaft. It is unacceptable for debris from the ventilation duct leading from the apartment to enter the common duct. When cleaning, care must be taken: sometimes nests of wasps or hornets are found in the ventilation.
Ways to improve ventilation in the apartment
What to do if cleaning the ventilation did not help? It is possible that the air circulation inside the apartment itself is disturbed. Having dealt with the causes of this violation, it is possible to improve the ventilation of the air in the living room.
Violation of air circulation between separate rooms
The first step is to repeat the test with a strip of paper, but at the same time open all interior doors. If the paper is attracted under such conditions, then the air circulation between the individual rooms of the apartment is disturbed. To improve it, it is recommended that when installing doors, make a gap between their lower edge and the floor of several centimeters.
If the doors are already installed or you don’t want to make such a gap, for example, in a bathroom or a bathroom, then you can drill a series of holes in the door, tilting inward. Subsequently, they should be decorated with a fine mesh. This design will provide ventilation with tight closed doors and will not violate the privacy of people in the bathroom or bathroom.
Airtight double-glazed windows
Another reason for the violation of ventilation can be the installation of plastic windows with double-glazed windows. In Soviet-built houses, the influx of fresh air from the outside was implied through small cracks and gaps in wooden window frames. Well established plastic windows in a fully closed state exclude such replenishment. As a result, the ventilation in the apartment is also disturbed. Therefore, if you are thinking about installing double-glazed windows, then preference should be given to models with a micro-ventilation system.
Already installed double-glazed windows, devoid of such functional features, easy to modify yourself. There are inexpensive ventilation valves installed on the window frame and sash.
HELPFUL INFORMATION: How to assemble a shower cabin with your own hands: installation and connection rules
In any building or structure, a ventilation system must be provided, which is laid during the construction process. The ventilation system is needed to remove polluted and humid air, which is formed as a result of human exploitation of plumbing and household appliances. Also, ventilation is the main element of a favorable microclimate in the room. Your tone and well-being depend on air quality.
According to the method of moving air flows, natural and artificial ventilation are distinguished. It also happens to be supply and exhaust.
Types of ventilation
Natural ventilation provides for air circulation, which is created due to the difference in air temperature in the street and in the apartment, and atmospheric pressure. These are the cheapest ventilation systems, so almost all old houses are equipped with them. But the system is not widely popular, as it is completely dependent on weather conditions.
Artificial ventilation involves air circulation, which is created using special equipment. These systems are currently used in all apartment buildings.
Supply ventilation brings fresh air into the room, and exhaust ventilation removes polluted air using ventilated appliances, and today is the most common system. Therefore, many people have such questions as how to clean the supply and exhaust ventilation. For those who have not experienced this, it will be difficult to perform this procedure, but the following information will help you.
Sooner or later, but any air circulation system becomes clogged and does not function well, and the main signs that you need to clean the ventilation in the house are:
- air blockage;
- a large amount of condensation on the windows and dampness in the apartment, darkened corners;
- the formation of a web around the entrance to the system;
- large accumulation of dust and small debris.
Causes of clogged ventilation
The most common cause of clogged air passages is a large number dust and dirt in the mines of these channels.
The second reason is the failure of ventilation devices.
In all houses for a total engineering system a special service is responsible, which has access to such work, so it becomes clear who should clean the ventilation in an apartment building. But every tenant has the right to clean the air channel of his apartment. Therefore, it is useful for you to learn how to clean the ventilation in the apartment yourself.
Ventilation cleaning methods
- manual cleaning. To do this, you need to carefully remove the grate and with the help of special detergents remove all grease, dirt and debris from your channel;
- cleaning with dry ice, which perfectly removes grease and then evaporates without leaving any smell.
Attention! At self cleaning it is forbidden to lower overall objects into the mines of air channels and use chemical reagents.
If you live in an old building and you are interested in the question of how to clean the ventilation in Khrushchev, then one mechanical cleaning method will not be enough. To do this, you need to take care of the following things:
- on new windows, install a ventilation valve that restores the natural flow of air;
- install a supply and exhaust device that removes moisture from the premises and provides an optimal atmosphere in your apartment. Such devices are mounted both in windows and on walls.
The most likely places for contamination of ventilation in the apartment are the bathroom and kitchen. Therefore, many are wondering how to clean the ventilation in the bathroom. For this, a mechanical cleaning method is suitable - 15 minutes and your air channel will be clean.
Ventilation systems in an apartment building
All modern apartment buildings equipped with two types of ventilation system:
- The vertical ventilation duct is led into the attic horizontal duct - through this system, air masses from all floors are directed into the horizontal duct and out.
- Vertical air ducts lead to the attic - through this system, air masses through a single ventilation shaft are directed to the roof.
But these modern systems ventilation does not always cope with its functions. In the first case, air masses from a horizontal duct can enter the apartments of the last floor. To avoid this, you must do the following:
- double the diameter of the horizontal box, it is better to do this work with a specialist so as not to disturb the engineering design;
- lead the air ducts of the last floors into the ventilation shaft above the horizontal duct.
In the second case, in order to improve the operation of ventilation, it is enough to lengthen the height of the air duct by one meter using a conventional pipe.
How to clean ventilation
Now that we know all about air circulation, we can now learn how to unclog this system. This process consists of five steps:
Before starting work, everything must be examined and checked. To do this, bring a lighter or a match with fire to the ventilation outlet. If the flame stretches into the channel, then you don’t have to worry about anything, but if it stands still, then your shaft is clogged and it’s time to find out how to clean the ventilation in the apartment.
Important! With a large accumulation of cobwebs, use another non-flammable method of checking.
mechanical cleaning
During this, you need to take a large ruff or steel cable and clean the air channel, try to clean as much as possible. Clean it of dirt, debris and grease. If this does not help, you need to take larger items and clean again. When cleaning the air channels, you must be careful not to run into a nest of wasps or other unpleasant insects.
Air circulation
To check the natural circulation of air, you can use a piece of paper and open wide the interior doors. If the paper flap does not respond, the circulation needs to be improved. To do this, it is enough to set the gap between the door and the floor at a distance of 4 cm.
Air supply
Natural ventilation is provided by open windows and doors. But in winter you won’t open them much, so you need to resort to additional ways air flow into the room. Today, almost every house has plastic windows that securely hold not only heat, but also air. Therefore, for all modern windows supply slots began to be provided. Cold air comes out of the cracks and mixes with warm air from the battery. In winter it effective method set the optimal microclimate in the apartment.
True, there are rooms in which supply slots may not be enough. In this case, supply wall valves are installed, which additionally saturate the room with fresh air.
Additional exhaust system
If, after installing the supply equipment, there is no necessary air circulation, then an additional exhaust system can be installed. That is, in the ventilation duct is mounted electric fan which pumps air. This provides your room with enough fresh air.
To finally understand how to clean the ventilation in the apartment yourself, the video will best help you figure it out:
If special equipment suddenly does not work for you, then it will not hurt you to know how to clean the crankcase ventilation. Maybe this is the reason. To do this, disconnect the battery and remove the air intake pipe. And then disconnect the throttle actuator and hose. Only then can you start cleaning all the other parts.
First, the kitchen (first air vent located exactly there) will not leave odors and combustion products domestic gas if you have gas stove. Poor exhaust from a gas boiler or column can lead to an almost complete absence of traction, which in some cases causes poisoning of residents carbon monoxide, but it is generally not advisable to clean it yourself.
Secondly, not working ventilation in the bathroom will increase the time required for the room to dry (reduce the amount of water vapor in the air), which will subsequently become main reason the appearance of black spots of mold and fungus on the walls and ceiling of the room.
Thirdly, clogged ventilation in the toilet (if the channel is shared by several apartments) may start to work “in reverse side” and you can fully feel all the smells from the neighboring bathroom.
Examination
How to check the performance of ventilation in the apartment? First, remove the grates mounted on the walls and rinse thoroughly from dirt and dust. Then put them in place and open the window in the kitchen. Attach a sheet of paper to the ventilation grille. If he is “drawn” to it, then the ventilation works fine. Then repeat this procedure in the bathroom and toilet, leaving the doors to these rooms open.
In the case when a piece of paper is not attracted to the grate, this most often means only one thing - the ventilation is clogged and it will have to be cleaned. The second reason for the lack of draft is the unauthorized redevelopment of apartments on the upper floors, as a result of which the ventilation duct was damaged. To eliminate such interference, you will have to file a complaint with the local architecture, since you simply will not be able to clean the ventilation in the apartment.
Another cause of poorly functioning ventilation is the replacement of old wooden windows on new plastic ones, which most time you keep tightly closed, blocking the natural flow of air into the apartment (and since the air does not come, then there is nothing to go into the ventilation). In this case, either always leave one window slightly ajar, or cut a ventilation valve into the window.
This video will tell you how to check the operation of ventilation and advise where to go in case of blockage.
Basic Rules
It is impossible for private individuals to clean the main ventilation shaft of the building on their own, since it belongs to common house property (it is better to file a complaint about poor ventilation with the management company and entrust all the work to their craftsmen). When the experts arrive, notify all the neighbors whose apartments are located above you so that they are not surprised by the suddenly “activated” ventilation, pouring black dust out of itself.
But the ventilation duct leading from your apartment to the common house shaft can (and even needs to) be cleaned on your own:
- Push aside kitchen furniture(if you are cleaning a channel in the kitchen) and move a stepladder against the wall. It is better to put a layer of newspapers on the floor, as something may fall out of the ventilation.
- Attach a sheet of newspaper to the bottom of the ventilation duct on masking tape (so that you do not have to wash the wallpaper or ceramic tiles later).
- Remove the grate covering the ventilation. Rinse it and wipe it (if you wish, you can replace it with a new one).
- Wear gloves for construction works and carefully rake out everything that you find in the ventilation duct, since you will not be able to clean the ventilation in the apartment in any other way. Be careful, glass or nails can get in, so it's best to arm yourself with a small spatula. If the ventilation duct is made in a panel or brick wall, it can contain a lot of "interesting", ranging from pieces of a frozen solution to the corpses of mice and birds.
- Remaining dirt can be removed from the channel with a vacuum cleaner.
- Reinstall the grille and check the draft again with the window open. If the situation has not improved, contact the management company for help.
In order for the air in the room to always be clean and updated in a timely manner, it is periodically necessary to clean the ventilation ducts.
Now we are not talking about chimneys that are polluted with soot - the usual ventilation system (both supply and exhaust) also needs to be cleaned.
Why and how is the air duct polluted?
There are always small particles of debris in the air around us that can enter the ventilation duct. For the exhaust duct, this is:
fat (which is removed through kitchen hood when cooking);
chemical compounds formed during the use household chemicals(detergents, washing powder) and smoking;
to a lesser extent - other small particles that can get into the ventilation.
Since the air in the apartment is usually clean, the exhaust ventilation duct becomes polluted relatively more slowly than the supply air.
If we are talking about supply ventilation (coming from the street to the room), then the pollution rate will be significantly higher. The reason is that outdoor air is much dirtier than indoor air (if we are talking about the city).
In addition to dust, it contains:
- pollen;
harmful compounds from exhaust automobiles, industrial emissions.
In addition, channels supply ventilation can be clogged with larger debris: leaves, poplar fluff, small insects. Of course, if there is a ventilation grill at the entrance to the duct, then this can be avoided, but air with a lot of impurities will still pass through and pollute the system.
Separately, it should be said about natural ventilation and forced ventilation. In the first case (when air passes through the duct without the use of fans), pollution will occur more slowly. In the second case, when more air passes through the system, it will also get dirty faster.
What gets dirty the fastest?
WITH The cross section of the air ducts - even in small private buildings - is quite large, therefore, on straight sections, although pollution occurs, it is very slow.
Much faster polluted places where small particles have something to "catch" on:
branching of ventilation ducts;
diameter differences;
filters (meaning not the filter element itself, but the areas near it, where the filter housing integrated into the ventilation system);
fans;
heat exchangers, heaters, coolers, humidifiers, dehumidifiers;
gratings, anemostats, diffusers.
Around these places, dirt accumulates the fastest. Later, when a decent layer of pollution has already formed in the “problem” areas, it begins to expand further along the duct.
Why is air pollution dangerous?
Pollution of ventilation is dangerous for several reasons:
The internal section of the ventilation duct is reduced. As a result, less air passes through the duct.
Further overgrowth of the air duct with dust is accelerated. If small particles could catch on somewhere, deposits will grow faster and faster in this place.
The load on the fans increases, which means that their wear is accelerated.
The microclimate in the room worsens: the level of humidity rises, harmful compounds may be present in the air that cannot be quickly removed, the room becomes hotter and stuffier. As a result, it harms both the human body and the room itself (the risk of mold and mildew increases).
The risk of reproduction of pathogens, for which a dirty environment is favorable, increases. The most common consequence in humans is an exacerbation of allergies.
If we are talking about ventilation not in an apartment or house, but on some industrial facility, then the deposition of dust in the duct is also a fire hazard. After all, dust flares up easily, which means that in the event of a fire, the air duct can easily become one of the ways the fire spreads through the building.
Such a fire can become especially dangerous at facilities where working area there are some combustible substances (which means that they will also be deposited in the ventilation system). At the same time, keep in mind that dust can flare up not only from an open fire: a spark that has arisen due to a static charge that has accumulated in the air duct can also become a cause.
How do you know if a cleaning is needed?
H To understand that the time has come to clean the air duct - it is not necessary to look into it regularly.
There are several signs by which you can determine that the system needs cleaning:
It became stuffy and hot in the room, if other conditions (weather, operation of ventilation and climate devices) did not change.
Dust on the floor and furniture accumulates very quickly.
Cobwebs accumulate on the ventilation grill and around it (both exhaust and supply).
Drafts that used to occur when opening windows or doors have now become weaker, or have disappeared altogether.
In addition to the "signs" listed above, there is also practical way Checking the performance of the ventilation shaft:
Remove the ventilation grill from the vent.
Rinse the grate.
Put the grill back in place. If the grate is not too dirty, the first 2 points can be skipped.
Open a vent or window.
Attach a sheet of paper to the ventilation grill. If it is “pulled” to the grate, it means that there is traction, and the traction is good. Note: thick paper- will not work, because even good traction will not always be able to “pull” a heavy piece of paper. It is better to use half a notebook sheet, a piece of toilet paper or a piece of newspaper.
How to check the condition of the air duct and determine the degree of contamination?
If you notice the "symptoms" listed above - it's time to check the condition of the duct.
This is done visually: inner surface ventilation ducts inspected, and the amount of deposits determined.
Inspection can be done in the following ways:
- After removing the ventilation grill (especially important if there is no inspection hatch). This inspection option allows you to see a small part of the duct, but does not require special equipment. Relevant if you want to check the status, but there is no hatch in the system (or it is, but in another part of the system).
Through a special hole - a hatch. The inspection hatch in ventilation systems must be designed when laying air ducts. However, hatches are usually located far from each other, so they allow you to inspect only a small part of the system.
Remotely, with the help of special video equipment. This option allows you to evaluate any, even the most narrow or geometrically complex section of the duct.
If the inspection is carried out by specialists, they may have equipment for video inspection at their disposal. It can be an endoscope with a camera and a backlight that transmits video to the screen, allowing you to evaluate all parts of the ventilation system.
Ventilation shaft inspection method using video equipment (video)
How often should the ventilation system be cleaned?
In practice, it happens that in many buildings the ventilation systems are not cleaned for years (and in ordinary apartment buildings - even for decades).
In fact, strict deadlines for inspections and cleanings exist only on some industrial enterprises. This is especially true for buildings where the production process leads to rapid contamination of the system. For example, this is relevant in Food Industry- extracts at such enterprises draw in fat and flour particles. For such systems, inspections and cleanings can be carried out frequently - and several times a year.
In residential complexes with management companies, as well as in commercial real estate, in which there are no factors that accelerate ventilation pollution, periods of regular inspections can be set, usually once every six months or a year. Such work is carried out by employees of the management company (or specialists who act on the order of the management company - if there are no “own” employees of this profile in its staff).
Self-inspection of ventilation ducts in your houses and apartments is recommended to be carried out periodically, also about once a year. Cleaning is done as needed.
Cleaning methods and technologies
WITH Air duct cleaning methods according to the principle of influence on deposits can be divided into:
Chemical.
Mechanical.
Cryogenic.
Chemical cleaning designed to remove fatty deposits (which mechanically almost impossible to remove completely).
The principle is to spray a special composition over the entire surface of the ventilation ducts, which corrodes plaque. After that, the exfoliated deposits are carried out along with the air,or sucked out with a vacuum cleaner. This kind of cleaning It is usually used in the kitchens of restaurants, bars, cafes, canteens, and other catering establishments.
mechanical cleaning (simply scraping plaque from the walls of the channel)can be performed with various equipment:
Metal brushon a cable (in fact, it operates on the same principle as a cable for cleaning sewers). To increase efficiency, the cable can be electrically driven. Suitable for not too serious pollution, if the deposits do not have a lot of fat.
At plant consisting of a device mechanical cleaning And vacuum cleaner . In this case, the brushes of the cleaning device scrape off the plaque, and vacuum cleaner - immediately sucks it. This method allowsclean up more serious contamination.
A robot equipped with a video camera and brushes. Allows you to work not "blindly", but to control the process on the monitor.
Scheme of mechanical cleaning using vacuum machine(vacuum cleaner)
WITH cleaned deposits can be removed either naturally (carried away with the air flow) or using vacuum plant(in fact - a powerful vacuum cleaner). It connects to the air duct and sucks all the dirt.
cryogenic blasting - the method is relatively new, being the most sparing and "clean". cleansing in this case, it is carried out with the help of “dry ice”, which is fed into the ventilation duct from a special installation.
In contact with the walls of the air duct, the "dry ice" granules instantly evaporate, creating microexplosions. It is they who clean off the entire plaque from the surface, while not damaging the walls themselves. During a microexplosion, only carbon dioxide remains from the granule, which is removed through the ventilation duct.
After such a procedure, the cleaned deposits are either removed from the duct naturally (carried away with the sweat of the air), or removed with a vacuum cleaner.
Mechanical ventilation cleaning (video)
Residents of apartment buildings: how to clean and what can you clean yourself?
WITH once about the main rule: residents of apartment buildings can clean their ownonly the section of the ventilation duct, which runs from the apartment to the "common" shaft. Mine - refers to common house property, and only employees of the management company or the housing office can clean it.
If you notice that the ventilation in the apartment has deteriorated, you can first try to clean "your" section of the ventilation duct.For work, it is recommended to use personal protective equipment - gloves, goggles, a "petal" respirator.
The stages are:
Remove the ventilation grill.It needs to be cleaned and washed..
Clear the space around the vent.
It is better to cover the floor around the hole with something - since dust and other deposits can fall out of it.
Use a flashlight to visually inspect the area as far as possible. If you have a monopod and an action camera at home, these gadgets can seriously help with the examination. Start video recording And put the camera on the monopod inside the ventilation duct.
Manually (with gloves, of course) remove large debris from the canal - if any. It is worth working carefully: inside the ventilation duct there may be nails, glass, and protruding sharp parts of a stone or a solidified solution.
By using metal brush scrape deposits from the entire surface of the duct.
Use a broom to sweep out debris.
Use a vacuum cleaner to remove fine dust from the channel.
Replace the grate.
Check if the traction has improved.
Usually, if the draft in the apartment's air duct has deteriorated, cleaning "your" area can help in rare cases. Therefore, after you have cleaned the ventilation duct to the common house shaft, it is better to call specialists who will clean it.
Disinfection of the ventilation system: why and how is it done?
In combination with cleaning the surface from deposits, disinfection should also be carried out - the neutralization of microorganisms that could multiply in the ventilation system.
To do this, after cleaning, another procedure is performed - spraying products based on hydrogen peroxide, peracetic acid or other reagents that kill bacteria inside the system. Such procedures can only be performed by specialists - they cannot be carried out on their own.
