Quick-Fit (QF) Back Pressure Flap Valve

Nordfab's Quick-Fit (QF) Back Pressure Flap Valve is a non return air valve, designed to prevent air circulating. Its primary function is to prevent the reverse flow of air within ductwork system. These valves are typically installed in ducts where airflow needs to be unidirectional, such as exhaust vents or ventilation systems. By allowing air to flow in one direction only, non-return air valves help maintain the intended airflow pattern and prevent the backflow of air from entering unwanted areas or contaminating clean air spaces. Available in galvanised steel, ranging from 160 mm to 710 mm in diameter.
