EC-HY 6/45 humidity-adjustable air vent

Humidity-controlled ventilation supply elements for air renewal in living rooms of apartments and houses. They guarantee a variable air supply of 6-45 m³/h depending on the humidity in the room, a pressure difference of 20 Pa, which partially eliminates cross ventilation, which is the cause of energy waste. The supply element is installed in a prepared 354 × 12 mm hole in the window frame using screws.
