Rectangular silencers are shipped as individual modules. However, they can be arranged in banks in any combination of sizes to meet the attenuation, air flow and pressure drop requirements and still fit the available installation space.

Materials:
The casing is constructed of 22 gauge galvanized steel. The baffles are made of 22 gauge perforated galvanized steel filled with an inorganic sound absorption material that is resistant to vermin and moisture.

Circular silencers are designed especially for direct installation in round duct where airborne noise from fans, or other sources, must be attenuated.

For maximum attenuation, the silencers are built with a square, insulated outer casing. This square configuration allows the packing of an unusually large amount of sound absorbing fill material into the casing. The result is that these models are among the most effective in the industry, with an overall length that is only twice the duct diameter in most sizes - a real advantage in tight spaces.

Professional CAD System Design can meet all engineering design and specifications.

Available in H.T.L. type 1, 2, 3 - 2” panel OR type 4, 5, 6 - 4” panel.

Class 1 Construction - medium, low pressure
Class 2 Construction - high pressure
