Silencing HVAC Fan Noise
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 to occupied spaces. This can often result in annoying or intolerable noise levels in offices, conference rooms, classrooms and auditoriums, etc.
one solution is place one or more rectangular or round air duct noise silencers between the fan and the occupied spaces. while reducing objectionable fan noise, duct sound attenuators can also reduce cross-talk transmitted from one space to another through the ducts to insure office privacy.
silent-mod duct sound attenuators are available in a wide assortment of geometries, models, and lengths. this choice in duct mufflers is to accommodate shape, pressure drop vs. airflow and noise reduction.
silent-mod hvac 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 vent noise silencer material that vibrates in the airstream.
