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.
