Industrial Silencers for Blowers, Fans and Vents

Rotary positive displacement blowers take in and discharge air in large pulses. Centrifugal blowers and fans create high frequency noise from blades spinning at high speed. Compressor bypass vents and relief valves release high pressure air or steam to atmosphere. All of them create noise that spreads through a plant and beyond.

Intake silencers reduce pulses and smooth airflow into the blower for better operation and a quieter surrounding. Discharge silencers smooth out the pulses going into the piping, protecting downstream equipment.

For centrifugal blowers, silencers absorb noise with acoustic material. For fans, the challenge is controlling noise without creating back pressure that lowers fan efficiency.

Vent silencers handle compressor bypass venting and safety relief and control valves, where venting at high pressure creates noise that can travel great distances.

Vacuum pump silencers cover dry vacuum pumps, including the jet port, and wet vacuum pumps, where separator silencers remove water from the air as well as noise.

Filters and filter silencers protect blowers with inline air filters, intake filters and intake filter silencers.
