CIRCULAR SILENCERS

Absorptive Circular Silencers

CM, CH (Medium and High Velocity Designs)
Price Absorptive Circular Silencers provide in duct noise attenuation for circular duct work while eliminating the need for circular to rectangular transitions.

CM, CH Series

Absorptive Circular Extended Casing Silencers

CMX, CHX (Medium and High Velocity Designs)
Price Absorptive Circular Extended Casing Silencers are designed with an expanded outer shell for applications where higher insertion losses are required at lower frequencies, while eliminating the need for round to rectangular transitions.

CMX, CHX Series

Absorptive Circular Film Lined Silencers

CMT, CHT (Medium and High Velocity Designs)
Price Absorptive Circular Film Lined Silencers provide a solution to unwanted circular duct noise, with additional protection against airborne contaminates and high levels of moisture, while eliminating the need for circular to rectangular transitions. The internal acoustic media is protected by a thin layer of Tedlar film that is wrapped around the media.

CMT, CHT Series

Absorptive Circular Extended Casing Film Lined Silencers

CMTX, CHTX (Medium and High Velocity Designs)
Price Absorptive Circular Extended Casing Film Lined Silencers have the improved insertion loss performance in the lower frequencies with additional protection against high levels of airborne contaminants and moisture. This is accomplished by increasing baffle thickness and wrapping the internal acoustic media with a thin layer of Tedlar.
