Consists of two individual elements, each 125 mm wide. The ventilation flaps are equipped with different counterweights, which makes individual vents react according to the wind pressure. Fresh air from the outside is fed into the space between the sash and door frame. This air is pre-heated there and rises up to the vent, where it then enters the room. It is easy to install and does not require any special drilling and machining. You can install this inlet on an already assembled window.
