Rectangular sound attenuators absorb fan and duct noise in HVAC systems.
Fit them near fans. Size to the duct and airflow.
What are rectangular sound attenuators?
Air distribution parts deliver air into rooms quietly and evenly. Linear slot diffusers spread air along ceilings, sound attenuators absorb fan noise in ducts, and round duct elbows and T joints route air to each outlet.
Good layout and sizing keep air velocity and noise low. Therefore, diffusers and attenuators are selected for airflow and room use.
