Designed for use in ventilation installations, CAR backdraught dampers prevent outdoor air entering if the fan stops running.

The damper flaps stay open while the fan is running and close automatically when it stops.

Backdraught flaps fit directly into the duct with a foam seal providing air tightness.

When fitted in a vertical duct, the flaps must open upwards.

Check the direction carefully when fitting to ensure the flaps open when the fan is runnning.
