VALVE F 120

The non-return valve prevents air from returning to the room when the fan is turned off. It helps in the fight against dust and odors, and also partially against the cold, especially if the fan is installed in the outer perimeter wall of the room. When the fan is turned on, the non-return valve wings will bend and allow the desired air flow to exit the room. Plastic body, cellophane membranes for easy extraction.
Application:
For all Cata models except B12. Simple spring-free design and easy installation (even retrofitting). Its application can eliminate/reduce unwanted backflow, which can be particularly beneficial in toilet and multi-user ventilation systems.
