Non-Return Damper 315 mm

Aluminum Non-Return Damper 315 mm.

The Non-Return Damper 315 mm. works as a one-way valve in high-flow ventilation networks. When the extractor pushes in the correct direction, the blades open with minimal resistance; when the flow stops or reverses, the closing springs seal the duct and prevent re-entry through inactive branches or from outside.

The aluminum body combines lightness, precise fit, and good mechanical strength, integrating into Ø315 mm sections with flexible or rigid ducts using metal clamps. This component helps maintain stable negative pressure, increases the airtightness of the circuit, reduces condensation during shutdowns, and protects carbon filters against reverse currents that carry dust or moisture.

In installations with several fans, “Y” branches, and cannabis cultivation accessories (silencers, controllers, intake fans), a well-oriented damper prevents a fan from pushing air into another line, stabilizes the microclimate, and improves energy efficiency.
