Metal Ducting Backdraft Connector - 100mm - 315mm
These metal ducting backdraft connectors allow for easy installation in any ducting run.
Made from steel and available in 4"/100mm, 5"/125mm, 6"/150mm, 8"/200mm, 10"/250mm and 12"/315mm.
Each Backdraft connector has 2 sprung openings which spring shut when no air is passing through. the one way valves allows air to leave the grow room, but stops cold air from outside being blown back through the ducting. This helps to keep an even temperature in your grow room, and eliminates backdrafts causing positive pressure in your grow space.
Position the backdraft connector in the ducting run where required, cut ducting, insert and connect with clips or clamps.
