Air-Box® Comfort window valve on a plastic window. Inexpensive and effective solution to the problems of stuffiness, humidity, fogging and mold indoors. Sealing the room with plastic windows leads to a violation of the norms of natural air exchange. The consequences of a lack of fresh air in the room are stuffiness, high humidity, poor health, headaches and the worst thing is the formation of mold. Air box Comfort will save you from these problems. The principle of operation of the window supply valve
Fresh air from the street enters the channel between the frame and the sash at the place of replacing a fragment of a typical seal with a special one. Then, through the supply valve installed on the top of the sash, the air enters the room.
Air flow control is carried out by moving the control knob, which in turn drives the damper, providing smooth control of air flow.
The Air-Box Comfort valve does not create drafts; if necessary, it can be completely closed.
