WeCooper Non-Return Valve DN 150 mm - Ventilation Flap Insert

Easy Installation: The duct damper opens and closes automatically and allows airflow in only one direction. The blades only open in the direction of the outgoing air when the damper is installed. The 150 mm duct damper is best installed horizontally and fully inserted into the duct. This also applies to vertical installation.

【HOME IMPROVEMENT】 Perfect for use in AC, tumble dryer ventilation, heating ducts, cooker hoods, or range hoods. Particularly suitable for use with an exhaust fan, bathroom fan, or attic fan.

High-Quality Materials: The damper housing is made of galvanized sheet steel. The dryer vent blades are made of aluminum. The shaft and spring are made of stainless steel.

The valve can withstand temperatures up to 140°C. Ideal for home use: the foam rubber seal on the flap reduces operating noise and provides an extra airtight seal. The check valve can be inserted directly into a non-flexible metal or plastic pipe, but for flexible pipes, you must use hose clamps to secure the check valve.
