Sound Attenuators

Commercial Acoustics sound attenuators are manufactured in many varieties, module sizes and materials, including no-fill models and models that eliminate acoustical fill entrainment into the air stream. Our industrial silencers are engineered for HVAC noise control in commercial industrial and institutional applications, including hospital and clean room systems.

Rectangular

Commercial Acoustics rectangular sound attenuators are manufactured in many varieties, module sizes, and materials, including no-fill models and models that eliminate acoustical fill entrainment into the air stream. Engineered for commercial, industrial, and institutional applications, including hospital and clean room systems. Options include heavier gauges, flanges, custom sizes, and custom materials such as aluminum and stainless steel.

Axial Fan

Commercial Acoustics axial fan inlet and outlet silencers feature conical air passages for efficient aerodynamic intakes and static regain outlets. Engineered for commercial, industrial, and institutional applications, including hospital and clean room systems.

Industrial

Commercial Acoustics models CA3 through CASTP are absorptive type silencers which feature fibrous filled dissipative design. These silencers are highly effective in the mid to high frequency range of 500Hz to 800Hz. They also feature a “straight-through” air passage for minimal back pressure.

Commercial Acoustics models RP8, R, D, S, C and ST are used to silence inlet and discharge noise on rotary positive displacement blowers. These silencers feature rugged construction, tuned expansion chambers, and include an absorptive section (depending on model) for critical applications.
