Return Air Vent Silencer

Air duct silencer reduces air noise traveling through hvac duct work and air ventilation systems.

Return air vent silencer. Air duct silencer reduces air noise traveling through hvac duct work and air ventilation systems. Model ra silencers are fabricated with a 4 102 thickness for installation in wall cavities or other applications where noise control is required in a low profile. Round 2 wire spring return 3 wire power open power close zone dampers. Closing supply vents actually puts undue stress on your hvac equipment.

Positioned directly above return grilles the rac prevents the transfer of occupant noise into the plenum above and prevents mechanical noise in the plenum from flanking through return grilles or open vents into the occupied space below. One closed damper probably won t make much difference but closing several dampers at once might make your system noisier. The compact design of the return air silencer ras provides an innovative solution for reducing plenum noise entering occupied spaces through return air openings and mechanical equipment noise transmission through transfer grilles. 24 and 36.

The ts 4 grille silencer is only 4 deep and is ideal for installation behind return transfer air grilles to reduce the transmission of sound into the duct chase or plenum. If the air moving through your system makes a lot of noise the first things to check on are. Duct silencer length open area and configuration are all determined by the noise control requirements and the design of the duct system. Let our engineering department help you with your air duct noise reduction needs.

Silencers are constructed with a 22ga galvanized steel outer casing and 22ga perforated galvanized steel baffles filled with inorganic glass fiber. Pottorff model ra silencer is designed for return air transfer openings or return air grilles between adjacent spaces. Silent mod hvac are fabricated from 22 18 gauge galvanized steel for superior strength and maximum sound transmission reduction through side walls. 24 and 36 lengths price.
