Valve KIV-125 refers to the effective types of devices that ensure the fight against stuffiness and humidity. This element is mounted on the wall, provides a constant flow of fresh air, does not require special maintenance. Consider its characteristics, features and customer reviews.
Design Features
The design of the air valve in question is identical to other similar devices. The element consists of a plastic tube inserted into a hole on the wall. On it, air is taken from the street and fed into the room. The existing difference between internal and external pressure contributes to this process.
It should be noted that the normal functioning of the supply valve is only possible with an exhaust hood or ventilation ducts. This is due to the fact that the spent masses must be diverted somewhere, if this does not happen, then the flow of fresh air will not be provided.
Device
The KIV-125 valve consists of the following parts:
- Cast aluminum exterior grill with mesh.
- A plastic duct in the form of a tube with internal sound insulation.
- Collapsible inner plastic head.
The insulator in the tube prevents the spread of cold in winter, and also dampens noise coming from the street, which is especially important for residents of busy areas or citizens living near railways and highways. The length of the insulator is shorter than the base, placed closer to the room.
The head is placed indoors, has a rounded configuration, the inner part is equipped with a special filter, a sealing ring and a control flap designed to adjust the amount of incoming air or complete overlap.
Control
The KIV-125 valve regulator is controlled by a circular disk located on the center of the body. In addition, this procedure can be performed using a special loop hanging from the tip.
The principle of operation of the locking mechanism is similar to the operation of the blinds. When pulling one edge of the rope, the shutter opens, a similar operation with the second part closes it. The degree of opening of the damper is determined using the scale on the cover of the head.
Destination
The main purpose of the supply valve 125 is to supply fresh air into the room, which allows us to provide the required rate for a person and prevent the formation of condensate on walls, windows, slopes.
The usual way of ventilation by opening windows has several disadvantages. First, the hardware wears out faster. Secondly, extraneous noise, smells, insects penetrate into the room. In winter, this process significantly reduces the temperature in the house and causes a sharp drop. After installing the device in question, these problems do not occur.
KIV-125 valve: characteristics
This product has several modifications that differ in the length of the pipe. The operating range at subzero temperatures is - 39 degrees Celsius. Below are the main parameters of the valve in question:
- The outer / inner diameter of the duct is 133/100 mm.
- The length of the working tube / heat insulator is from 40 to 100 cm / 31.2 cm.
- Diameter / thickness of the head - 175/66 mm.
- The working air supply is 20 cubic meters. m / h at a pressure of 5 PA.
- A similar indicator at a pressure of 10/20 Pa - 35/50 cubic meters. m / hour to the maximum.
- The noise reduction indicator at a distance of 100 mm from the tip is up to 39 dB.
The price of KIV-125 Finnish production is from 4.5 thousand rubles and above. Chinese counterparts are much cheaper.
Advantages
In the supply market, this device has a lot of competitors. Consider why the KIV-125 air valves are better than competitors.
Main advantages:
- It is possible to adjust the volume of incoming air or completely stop its supply.
- The unit is completely autonomous, does not require a network connection or other auxiliary elements.
- No noise at work.
- Provides the necessary amount of air.
- It is equipped with a special filter element.
The disadvantages include the lack of a supply fan, which reduces the efficiency of the system. However, this issue is solved by additional installation of the fan. It is especially relevant in the hot season, when natural traction decreases.
Manufacturers
The original manufacturer of the device in question is the Finnish company Flakt Woods. However, the popularity of the unit led to the release of its analogues in China and Russia. The price of KIV-125 in this case will be about one and a half times lower. Judging by customer reviews, such models are practically not inferior to the original in terms of efficiency and design. Also on the market you can find an analogue from Italian manufacturers. Their cost is the same as that of the Finnish modifications. Products differ in that they have not a round, but a square head.
Care and maintenance
It is recommended that the wall ventilation KIV-125 be cleaned twice a year from dust to prevent clogging of the filter. For the procedure, it is necessary to disassemble the head and remove the filter. Complete removal of the duct is not necessary. It can be cleaned with a vacuum cleaner. Periodically remove leaves, debris, cobwebs and other contaminants from the outer grill.
Rinse the filter element in a mild soapy solution. Then it is necessary to dry it thoroughly and install it in place. With a long absence of tenants, you can set the unit to minimum ventilation. To do this, remove the shutter plugs, which serve to completely shut off the air supply. This will allow you to get a small gap, and the air in the apartment will not stagnate.
Installation
Installation of the air valve is as follows:
- Choose a place to place the device.
- A hole with a diameter of 13.3 cm is drilled in the wall.
- Try on the duct. If necessary, the excess part of the pipe is cut off.
- A heat insulator is placed in the duct, as close as possible to the side of the room.
- The tube is inserted into the prepared hole.
- From the street to the duct, the grille is fixed with bolts.
- From the side of the room a head is installed, which is fixed by means of a sealant and four screws.
Mounting Features
The supply valve type KIV-125 can be operated in residential, office or industrial premises that need to improve air exchange. This can be a kitchen, toilet, bathroom, smoking room, work shops with harmful substances released into the air.
It should be remembered that the room should be equipped with an extractor hood, which will serve to remove excessively polluted or moist air masses. Otherwise, the valve will be ineffective. To expand the functionality, the system can be supplemented with a fan.
The valve can be placed on the wall under the windowsill near the battery. In this case, the incoming air will be slightly heated by the radiator, however, the adjustment of the dampers will be somewhat difficult.
Also, the device can be placed on the wall near the window opening at a height of 1.8-2.0 meters from the floor. The distance to the slope of the window should be at least 300 millimeters. Air will flow into the upper part, mixing with masses of room temperature. If there are no windows in the room, the valve is mounted at a height of 2 meters from the floor,
It is worth noting that the head with the indicated types of placement is hidden behind the curtain, and is not visible. In this case, the air flow rate will decrease.
Consumer Reviews
The owners of the supply valves note mainly positive points. The unit does not require special maintenance, easy to install, does not spoil the interior and exterior. In addition, it provides a constant flow of fresh air in the right amount and works silently. Now the need to open and close windows has disappeared, trying to achieve the desired effect. In addition, the accessories do not wear out so quickly. Among the minuses, some owners note the relatively high price of the original devices. However, their counterparts practically have the same efficiency and design.
