Duct Silencers
Duct silencer are acoustical products that can go inline at either the supply or return ends of a NVAC system to reduce the amount of noise emitted from the system. These silencers are custom made to make sure the CFM is assured to keep the safe and quiet HVAC system.
Noise S.T.O.P.™ Silent-Mod DuctSilencers™
Silencing HVAC Fan Noise and Other Unwanted Noises Through Ductwork
Rectangular Silencers
Circular Silencers
Industrial Fan Silencers
Elbow Silencers
Custom Size Module Silencers

The fans that move air through modern HVAC systems are noise generators. The ductwork carrying conditioned air to occupied spaces throughout the building can often act similar to the old fashion “speaking tubes” that can conduct intrusive and annoying fan noise, cross talk and other noises to and from occupied spaces. This can often result in annoying or intolerable noise levels in offices, conference rooms, classrooms, auditoriums, or anywhere ductwork is present.

Silent-Mod DuctSilencers™ are available in a wide assortment of geometries, models, and sizes to accommodate duct shape.

Silent-Mod DuctSilencers™ shells are fabricated from 22-18 gauge galvanized steel for superior strength and maximum sound transmission reduction through side walls. No flimsy 26 or 24 gauge material that vibrates in the airstream.

Noise S.T.O.P Quiet Duct Wrap™ is also available for additional noise and thermal control.
