Return Air Vent Silencer

If the air moving through your system makes a lot of noise the first things to check on are.

Return air vent silencer.

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. 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. One closed damper probably won t make much difference but closing several dampers at once might make your system noisier. Air duct silencer reduces air noise traveling through hvac duct work and air ventilation systems.

Pottorff model ra silencer is designed for return air transfer openings or return air grilles between adjacent spaces. Closing supply vents actually puts undue stress on your hvac equipment. 24 and 36. Round 2 wire spring return 3 wire power open power close zone dampers.

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. Duct silencer length open area and configuration are all determined by the noise control requirements and the design of the duct system. Air duct silencer reduces air noise traveling through hvac duct work and air ventilation systems. 24 and 36 lengths price.

Our team is experienced in evaluating factors such as air volume and velocity and will engineer duct silencer solutions to achieve all of the performance specifications on your project. 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. Let our engineering department help you with your air duct noise reduction needs. No flimsy 26 or 24 gauge vent noise silencer material that vibrates in the airstream.
