Аir curtains

The air curtain is a device whose main purpose is to prevent the penetration of air masses through openings (doors, windows, etc.) from the street to the premises and vice versa. The air flow created by the device does not allow cold air masses to pass into the room, and the warm indoor air does not leave the room. For this, heated air is used, which also plays an auxiliary role in heating the room. It is also possible to use the air flow as a kind of "filter" - it does not allow street air containing dust, exhaust gases, etc. Learn more about air curtains here!
