Windsor Industrial Products


We produce a comprehensive range of noise attenuators to established and proven performance specifications to suit rectangular and cylindrical duct installations.

We can provide light weight attenuators to SMACMA minimum standards for use in H&V applications or in any situation where cost is of prime consideration.

Types of Attenuators

Our range of industrial grade attenuators incorporates features such as rolled steel angle flanges and perforated galvanised steel facings to all linings. They can also be built in stainless steel or finished with special paint coatings.
All attenuators supplied by us use a permanent inert and flameproof acoustic absorption material and have a guaranteed performance.

Cylindrical attenuators are designed primarily for use with axial flow fans and circular ducts, and end flanges are provided with tapped holes to match standard fan drillings.


To complement the range of steel attenuators, we can also supply equipment in glass fibre reinforced plastic and PVC for fume cupboard and other corrosive applications. We can also manufacture special attenuation equipment to comply with unusual or difficult specifications.
Our range of Stainless Steel dairy exhaust attenuators feature easy access doors and removable splitters for cleaning and inspection.
