Main Features
Check valve designed for bathroom fans. It can be installed with the following models: OR-WL-3200/100 and OR-WL-3201/100. The use of a check valve on the fan's flange prevents the air from flowing back into the room and the ingress of dirt from the ventilation ducts. The use of the device does not limit the fan's efficiency, but has a significant impact on the air quality in the ventilated room.
