## Description

Backdraft Shutter Damper

Review: good spring , no draft . - very good , works as it should without backdraft . far better than manrose with the week spring that might as well not be there.
Review: Solid kit. - Well made.

## Features

- HOME IMPROVEMENT: Pipe cover flap, butterfly valve. Especially suitable for inserting into 150mm round pipe or flexible hose. Perfect for use in Tumble Dryer, bathrooms, garages ,air conditioners, extractor fan, extractor hoods, Hydroponics, In-Line Extract Fans, and ventilation systems
- EASY INSTALLATION: The duct damper opens and closes automatically, allowing only one-directional airflow. The damper blades open only in the outflowing air direction when the shutter is installed. The duct valve for 6-inch duct best installed in a horizontal position and inserted fully into the duct. This also applies to vertical installation
- HIGH-QUALITY MATERIALS: The casing of the shutter is made of galvanized steel sheet. The dryer vent valve blades are made of aluminium. The shaft and spring are made of stainless steel. The shutter is able to withstand temperatures up to 140°F
- GREAT FOR HOME USE: The foam rubber sealing on the damper reduces operation noise and provides extra air tightness. The back draught valve can be inserted into a non-flexible metal or plastic duct directly, but for flexible duct you need to use steel duct clamps to secure the backdraft damper
- WARM PROMPT: Please kindly confirm the size you need before ordering to make sure a fit
