Backdraft Damper 150 mm

Buy 150 mm Non-Return Damper for indoor growing

In professional indoor ventilation systems, the 150 mm Non-Return Damper acts as a one-way valve: it allows flow to pass when the extractor pushes in the correct direction and closes automatically when the flow stops or reverses.

Made of aluminum, it combines lightness and mechanical strength, integrating into Ø150 mm networks with flexible or rigid ducts using clamps. This piece stabilizes negative pressure, improves circuit tightness, reduces condensation during stops, and protects activated carbon filters.

In environments with cannabis growing accessories (extractors, intractors, silencers, “Y” branches), a non-return damper prevents unwanted re-entries, leaks through undesired lines, and external contamination from dust or insects.

The operation is automatic and does not require electrical power or complex maintenance: just respect the installation direction and periodically check the cleanliness of the mechanism.

In the Hydroponics Blanes catalog, Grow Shop in Spain and trusted Grow Shop, there are compatibilities, technical advice, and discreet shipping, along with options in cheap indoor grow tents to complete the installation.

Indoor Growing 150 mm Non-Return Damper

The 150 mm Non-Return Damper is essential to maintain a defined flow direction in Indoor growing. By preventing return, the circuit maintains tightness, odor control becomes more effective, and the microclimate shows fewer temperature and humidity peaks between light and dark cycles.

What is the 150 mm Non-Return Damper for?

It serves to block air backflow and allow circulation in only one direction. It benefits stable negative pressure, makes it harder for pests and dust to enter through the duct, and prevents air from returning to the extractor or escaping through the intractor when the system is stopped.

Indoor growing accessory 150 mm Non-Return Damper

As an indoor growing accessory, it stands out for its easy installation, compatibility with standard sizes, and spring closure that responds immediately. It fits in medium tents and rooms, and works with filters, extractors, and insulated ducts for consistent and efficient ventilation.

What is the 150 mm Non-Return Damper used for?

It is used in extraction and intake lines where backflow needs to be prevented: tents, drying areas, technical rooms, and rooms with several branches. Useful when several lines share an outlet to the facade or roof, preventing a fan from “pushing” air into another inactive line.

Instructions for use 150 mm Non-Return Damper
