QF Silencer With Baffle

QF silencers with baffle cut airflow and fan noise in the larger Nordfab QuickFit duct sizes. The internal baffle (pod) gives extra attenuation over a plain-bore silencer, making these the choice for bigger extraction systems where fan noise carries into working areas or outside.

Galvanised steel with QuickFit rolled ends, each silencer clips straight into the duct run with Quick Clips. Available diameters run from 300mm to 710mm (300, 315, 350, 400, 450, 500, 560, 630 and 710mm), with a choice of casing lengths — 0.5m or 2m in most sizes (0.5m or 1m at 710mm); the longer body gives greater attenuation.

For smaller ducts, or where an unobstructed bore is required, see the QF silencers without baffle (100–710mm).
