Product Details

Product Description

Round Ducting Silencers for round ducts with connections in accordance with spiral duct standards. The silencers are effective in reducing noise in the duct, external cover made from circular duct with a 50mm glass fiberglass wool attenuating layer. In installations where noise reduction is particularly important, two silencers can be used together.

This is very effective for the most efficient noise reduction and the silencer should be placed immediately behind the fan or elbow. The silencer should be used in conjunction with an insulated fan, as noise reduction is required in both the duct and the surroundings.
