The supply valve is installed in the wall, does not affect the window structure and does not affect the soundproofing and thermal characteristics. Suitable for installation: 1. Rooms in country houses 2. Office premises 3. Any premises with sealed windows 4. Any premises with a constant crowd of people 5. Premises with seasonal operation: schools, universities. 6. Apartments in urban apartment buildings. WHAT PROBLEMS IT SOLVES 1. Obstruction of fresh air into the room when using exhaust fans, air conditioners and plastic windows. 2. The development of various microbes, fungi and mold on tiles and wallpaper due to poor ventilation. 3. Providing air to people who are constantly in the room. 4. Fogging of plastic windows. 5. The appearance of the smell of dampness and stagnation of air upon returning home from trips or to work after the holidays. OPERATING PRINCIPLE Existing extractor hood, removing exhaust air from the kitchen and toilet, creates a vacuum and due to this, fresh air from the street enters the room through the supply valves KIV-125. Accordingly, if the supply valve installed in the wall supplies air only due to the vacuum created by the hood, then for the effective operation of the valve, the hood in your apartment should work well. Otherwise, instead of a constant flow of air through the valve, air will circulate in both directions, both inside and outside, and when warm and humid indoor air comes into contact with cold surfaces, condensation will form inside the valve and the valve will freeze. Aerodynamic characteristics of the inlet valve: at a discharge of 10 Pa (creates a natural exhaust), the productivity is -36 m3 / h, at a discharge of 20 Pa (creates a mechanical exhaust), the productivity is -60 m3 / h.
