KIV-125

Plastic windows have become a part of people's lives. Because modern technologies offer the best solution: tightness, good sound insulation and minimal heat loss. These factors make it possible to achieve comfortable conditions for residents, which makes it possible to enjoy their vacation all year round. But this solution has a downside - the formation of condensation, which increases the humidity in the room. Because of this, the human condition deteriorates and the durability of electronic equipment and finishing elements decreases. To prevent this from happening, the editors of the YaNashla website have prepared for you a rating of the best supply valves for 2020.

Purpose of the element

After installing the plastic structure, the natural circulation of air flow becomes worse. Less oxygen enters the room, and carbon dioxide and fumes cannot escape. All this has consequences:

Condensation formation;
Mold development;
Unpleasant odors begin to appear;
The residents' health is deteriorating.

These problems are solved by the simple installation of an inlet structure. The main feature of this solution is ventilation of the living space without significant heat loss. Thanks to small holes, carbon dioxide and moisture leave the room, improving air circulation. Maintaining a good microclimate in the office or at home will become much easier, which will stop the development of diseases and mold.

The efficiency of plastic windows is not lost; they still work 100% and do not allow heat to escape even in winter. At the same time, the air becomes cleaner and fresher.

To ensure that the product is not useless, it is important to consider a number of features when installing it. This is the only way to achieve better results:

The hood must work correctly;
Outdoor temperature should be no higher than 5 degrees;
Natural air exchange between rooms is mandatory. To achieve this, you need to open the doors in the room or buy products with a gap of 1 cm between the floor and the lower edge of the structure;
Ensuring a tight seal at the entrance door.

Design Features

There are dozens of different models in stores, but they are all united by one design:

Air intake. The product is located on the outside on a plastic frame. Designed to receive and transmit air flow from the street. Installation takes minimal effort and is completed in a few minutes.
To prevent precipitation and dust from seeping into the room, a special canopy is installed on top.
A telescopic channel is used to enter the air flow into the room. In appearance, this element resembles a special tube. It is mounted into the window body using milling and installed using a mounting sleeve.
The incoming air passes through a special hole and enters the internal unit, which launches it into the room. This element consists of a nozzle, filter and regulator. Installation is carried out indoors.

Arrangement rules

The design of air exchange systems in brick buildings is usually created at the design stage. It is necessary that the air lines meet all the requirements of SNiP 2.04.05-86. Since air ducts, channels and shafts can be structurally connected to each other, which makes them a source of fire hazard, their laying must comply with SNiP 41-01-2003. What to pay attention to:

It is prohibited to construct ventilation ducts in external walls. Such placement will inevitably cause condensation.
A vertical location of the shafts is recommended. If this is not possible, then the angle of inclination of the air line must be at least 60° to the base of the building.
If there is high humidity in the room, then installing air channels in the walls of such rooms is strictly not recommended. Due to this placement, condensation may appear in the mines, which can lead to the collapse of the channel.
It is possible to combine air ducts from bathrooms in the attic if they are on the same side of the house. Horizontal sections in unheated attics are made of double insulated 40 mm expanded clay concrete slabs, with an air cavity between them equal to the thickness of the slabs.

There are a number of requirements for the placement of ventilation ducts in brick walls in relation to the roof. The location of the outlet of the ventilation ducts, closer than 2.5 m from the ridge, indicates its normalized height above the roofing material is more than 50 cm. If the outlet of the ventilation pipe is located from the ridge at a distance of 3 m and further, then its height is calculated as follows: conventionally draw a straight line from ridge to the pipe at an angle of 10°. The place of visual intersection shows the required height of the pipe from the roof surface.

If the air channel is located more than three meters from the ridge, its height from the roof cannot be less than 50 cm.

Principle of operation

This element functions as follows:

Air enters the telescopic opening;
Purified from some harmful elements;
Penetrates indoors.

During this process, excess carbon dioxide is squeezed out. This happens due to the difference in pressure, since cold air enters and warm air is expelled (the recommended temperature value is no more than 5 degrees Celsius). If you violate the indicator, no difference will occur, and the device will be ineffective. Therefore, if a person lives in warm areas, then there is no need for this device, since it is easier to ventilate the premises manually. There will be heat loss, but not as critical as in cold weather.

What is taken into account during installation?

For efficient operation, not only the temperature difference, room features, etc., but also the correct installation are taken into account. Installation should only be carried out by a person who knows all aspects or is familiar with the basics. If the user has no experience in this area, then it is not recommended to assemble the product yourself, despite the ease of work. After all, to carry out this process, you must carefully follow the requirements and carry out each step in accordance with the instructions. For example, to install a slot valve you will need:

Remove the small piece of seal that is present on the frame. A specific value is deleted; the entire upper seal cannot be removed unless required by the design of the device.
A new sealing element is installed, which is several times thinner;
Self-tapping screws are used to secure the equipment.

Professionals can perform installation in a different way. Pull out the old glass and install a new one, which will be smaller. In the place where the gap is formed, an inlet structure is installed. This method requires a lot of money, so it is used only when a person plans to completely replace the windows.

Choosing a quality system

Before choosing a system, you need to keep the following criteria in mind:

Cost : It can vary widely as there are many companies producing inlet valves nowadays. All of them differ not only in functionality, but also in the materials used. It is worth noting that the cost of the valve itself reaches about half the cost of a whole window;
Installation area: a modern ventilation system can be installed not only in the window itself, but also through the adjacent wall. It is worth saying that the second method is much more expensive and more difficult than the first. In this regard, you should be very careful when choosing a ventilation valve;
Control method : all ventilation is manual or automatic. The first method requires a lot of control over all kinds of sensors. After all, not only humidity, but also air quality will depend on this. As for the second method, everything is very simple. The system fully automatically adjusts the room climate and regulates air humidity;
Sound insulation level: currently all systems have good noise protection. Due to this, the population will not experience discomfort during the operation of the housing. It is worth noting that the supply valve should be selected in accordance with the requirements of the residents and the installed window;
Meets air exchange standards: any standard valve can produce fairly clean air that meets all modern standards;
Performance: You should also pay attention to the performance of the system. The fact is that the valve must provide a flow of fresh air even in unfavorable conditions. An example is condensation and its freezing at low temperatures. I would like to say that the formation of condensation depends on the temperature and humidity of the air.

Pros and cons of an inlet valve

After a person has become familiar with the design features and installation method, it is important to analyze the advantages and disadvantages of this device in order to make an objective assessment of its usefulness.

The advantages of the device include:

The light level does not change. However, this is only typical for small models where the product is installed only on the top of the frame. In other cases, the sun's rays will encounter an obstacle, which is why the illumination may be insufficient.
The valve takes in only the volume of air needed by the room. This creates a more comfortable microclimate without drafts and reduced heat;
Thanks to high-quality circulation, excess moisture quickly disappears, even if a person cooks on the stove all day.
Due to the absence of drafts, the product can be used indoors with small children who are often sick.
The design of the device does not allow extraneous noise from the street into the apartment. Therefore, loud screams will not distract from relaxation.
The valve operation is manually adjusted, but there are also models that support automatic adjustment.
The installation can be carried out by an ordinary user who has at least some experience in the construction industry and knows how to handle tools.
Using the valve does not require special knowledge; it is enough to read the instructions once and the principle of operation and adjustment will become clear.

Despite the large number of positive aspects, the product is not without disadvantages:

Slight reduction in noise insulation properties;
High cost for high-quality models, especially if you choose a product with automatic regulation;
If you plan to install a valve in a two-room apartment, then one device is not enough to ensure normal regulation. In this case, it is recommended to use 2-3 pieces;
If you live in an area with severe frosts (below -25 degrees), frost may form at the top, which will interfere with normal inflow.

KIV/KPV-125

The supply climate valve KIV-125 / KPV-125 is designed to supply outdoor air to rooms with constant presence of people, rooms with a fireplace, boiler rooms, basements and many others. The use of the valve is most important in rooms with sealed plastic windows and in rooms with high humidity. Please note that an important condition for the correct operation of the KIV valve is the presence of an existing mechanical hood in the house of at least 60 m3/h.

Head made of environmentally friendly ABS plastic (impact-resistant, non-toxic, durable)
Possibility to place anywhere on the external wall (even in rooms without windows)
Possibility of installation in a room with already completed renovation (clean)

The valve dampens noise from the street by one and a half to two times compared to open windows

With the windows open, the noise from the street is at least 56 dB, and the valve reduces it to 36 dB and lower (this is quieter than a whisper).

How the head of the KIV-125 works

The internal valve head is designed to distribute and regulate air flow. It is made of environmentally friendly impact-resistant ABS plastic, resistant to temperature changes and ultraviolet radiation.

The inner head consists of:

Interior with leaf type damper and O-ring
Adjustment unit
Coarse filter EU3
Head covers
Adjustable knob that allows you to easily open and close the valve flap

Valve Maintenance

To ensure good valve performance, it is sufficient to regularly perform the following procedures:

Clean the filter in the head by rinsing it with water - once every three months
Clean the pipe with a vacuum cleaner - once every six months
Clean the outer grille from large dirt - once a year.

Valve recommendations

The supply valve will work correctly only if there is a hood in the house (it is desirable that the hood be mechanical)
It is better to place the valve at the top of the wall due to the characteristics of air convection
For residential apartments, a supply valve must be installed in each room, except for the bathroom, toilet and kitchen areas, in which the hood should be located
For rooms with a gas boiler, the number of valves is determined by the power of the boiler, for example: up to 30 kW - 1 piece, up to 60 kW - 2 pieces, etc.
It is better to entrust the installation of the valve to professionals rather than trying to install it yourself

Types of models

Today, hundreds of models are sold, produced by various brands. You can find both a cheap option and an expensive one. The main difference lies in three criteria:

Material of manufacture. There are plastic, metal and wood structures.
How is air regulation carried out: mechanically or automatically. In the first option, a person must control the flow independently using a special curtain. This method is more difficult to implement, since you have to constantly adjust the opening level to achieve comfortable conditions. Automatic models are simple, you just need to install them and that’s it, the rest is under the product’s own control.
The method of flow entering the apartment or office.

The last point is the most important, since the effectiveness and quality of the product depends on it. So there are three types of structures according to the method of entry:

Folded ones are a cheap option that is suitable for one-room apartments. The capacity is small, but sound insulation is maintained. The cold flow penetrates through a special hole that is cut in the frame. Installation of the product takes a minimum of time and does not require intervention in the main structure of the window product.
Slotted - these models are widely used. Ventilation of the room is carried out due to the movement of air flow in a special valve. The product is equipped with an air intake and a control element. To install this option, it is not necessary to dismantle the window. The advantage is high throughput. Disadvantage: sound insulation is reduced.
Invoices – products of this type are common in industrial premises. The advantage of the models is excellent ventilation of the room. Disadvantages - the thermal insulation properties are reduced; the window is completely removed for installation.

Installation of the supply valve

It is better to entrust the installation of the infiltration valve to craftsmen, since making a through hole in the outer wall requires an expensive diamond drilling installation. Thanks to the rotary drilling technique using rock-cutting tools reinforced with diamonds, installation of wall-mounted devices will take little time and will not spoil the final finish of the apartment.

By entrusting the installation of the supply valve to certified specialists, you can also minimize the possibility of freezing during the cold season.

Rules for installing wall-mounted KIV-125:

So that fresh air can enter the apartment through the valve, it is installed on the load-bearing (outer) wall. If the apartment has one load-bearing wall with access to a loggia or balcony, then in this case it is also possible to install a valve.
You can install a valve between the window sill and the radiators - the air entering the apartment will be heated by the radiator.
Natural ventilation must be in good working order. For the valve to operate effectively, the fresh air supply must “push” the exhaust room air into the exhaust ducts. Before installation, check the serviceability of the ventilation ducts.
It is better to place the valve next to the window. This way it can be hidden behind a curtain and the outer grille can be more easily maintained.

Installation nuances

The use of supply valves is relevant both in residential, industrial and work areas that need improved air exchange. It is not recommended to use them in the following rooms:

kitchen;
smoking room;
toilet and bathroom, or combined bathroom;
dressing room;
corridor;
work areas where harmful substances are released into the air.

In the above-mentioned cases, the room must be equipped with an exhaust hood that will draw excessively humid or polluted air outside. The inlets are suitable for installation in the bedroom, boiler room, living room, and office.

The location of the valve can be:

A section of the wall under the window sill, near the battery.
A section of the wall near the window opening, at the height of its last third (approximately 1.8-2 m from the floor). The window must be at least 30 cm from the slope.

KIV 125 valve heads near the heating radiator

In the first case, the incoming air will be partially heated by the radiator, but in this case it is not very convenient to adjust the position of the damper. In the second, it will enter the upper part of the room, mixing with air at room temperature.

If there are no windows in the room, the valve is installed at a height of approximately 2 m from the floor (for an ordinary living space with a ceiling height of 2.3-2.5 m).

In both cases, the advantage of this location is that the head is covered with a curtain. Thus, it will not be noticeable, and the air flow speed will decrease.

Stages of work

Installation of the KIV-125 air valve is as follows:

The location of the valve is selected.
A hole with a diameter of 133 mm is drilled in the wall.
A “fitting” of the air duct is performed. If necessary, part of the pipe is cut off.
A heat insulator is inserted into the air duct - as close as possible to the “room” side.
The air duct is inserted into the hole.
An aluminum grille is bolted to the air duct from the outside.
From the inside, the inner part of the head is inserted into the air duct, and through an o-ring it is fixed to the wall with 4 screws.
The head is assembled.

Mounting hole for KIV 125

A specialist will charge approximately 1.5-2 thousand rubles for installation.

Maintenance and care

Periodically - about 1-2 times a year - it is recommended to clean the product from dust that can clog the filter, and small debris that can accumulate in the pipe. To do this, you need to disassemble and remove the head and remove the filter.

It is not necessary to completely remove the air duct - just blow it out with a vacuum cleaner from the inside. You can also evaluate the condition of the external grille - leaves, poplar fluff, or cobwebs may get stuck on the blinds or mesh.

Filter – it is recommended to wash it in a mild soapy solution, then dry it thoroughly and put the head back together.

In case of departure, the product can be set to minimal ventilation so that the air in the apartment does not stagnate. To do this, plugs are removed from the head damper, which allow the air supply to be completely blocked.

Without plugs, even when the damper is completely closed, a gap will remain, allowing fresh air to flow into the room.
