Description

Back Draft Damper to reduce linear backward air flow. 

Nordfab QF In Line Back Draft Damper used to reduce backward air flow in ducting lines. The standard model is designed particularly for use in a horizontal line. Back Draft Dampers for vertical operation are also available above. 

This is NOT an explosion isolation device. 

Quick-Fit ducting has been used in a wide variety of applications, wherever dust collection or fine particulate transfer is required. Its QF rolled ends for use with QF clamps, allow quick assembly, disassembly and relocation. It clamps together in seconds without welds, bolts, screws, flanges, special tools, precise measurements or specialized skills. So, it cuts installation – and ducting related downtime – by more than 40% over traditional ductwork. See more benefits below.
