Back draft shutters

At S&P, we provide you with a variety of back draft shutters options so you can select the best option for your installation.

In our range of back draft shutters you can find metal and plastic back draft shutters, which will allow you to avoid air ingress when the fans are not working and prevent bad smells from entering.

Discover them, and select the one that best suits your needs:

CLAR, back draft shutters for circular conductor

The CLAR range of circular duct check valves are designed to prevent air from entering when fans are not in operation. The working positions of these fans can be: horizontal flow or vertical flow upwards, provided that the air velocity is higher than 11 m/s.

CAR, metal back draft shutter

The CAR range's back draft shutters prevent odours, drafts and draughts from entering and prevent heating leaks when the exhaust fan is not working. These non-return gates are installed between the exhaust and duct.

CM 130 - plastic back draft shutter

The plastic back draft shutters of the CM-130 range prevent odours and draughts from entering, and prevent ventilation leaks when the exhaust fan is not working. These non-return gates are installed between the extractor and the duct.
