Circular Duct Silencer
These easy to fit silencers for circular ducts, come with a spiral duct standard compliant connection. It effectively reduces noise in the duct.
Where noise reduction is a critical factor, two silencers can be used together.
For the most effective noise reduction, the silencer should be fitted immediately behind a fan or bend. But can be fitted either side of the fan to maximise the noise reduction inside and on breakout.
Manufactured from galvanised steel with a perforated inner liner 50mm of insulation and an outer skin of galvanised steel.
