Industrial Silencers for Blowers, Fans and Vents

Intake, discharge and vent silencers for rotary PD blowers, centrifugal blowers, industrial fans, compressors, relief valves and vacuum pumps.

Quieter Operation

Lower noise levels.

Smoother Airflow

Pulses reduced.

Protects Equipment

Downstream safety.

Filter Silencers

Protect the blower.

How It Works

Why Blowers and Vents Need Silencers

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.

Warning Signs

Signs You Need a Silencer

  • Noise complaints from staff or neighbors

  • Uneven airflow into piping

  • Failures in equipment after the blower

  • Loud venting from compressors or valves

  • Water carried over from wet vacuum pumps

Vent and Vacuum

Vent, Vacuum Pump and Filter Silencers

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.

Silencer Types

Silencers by Application

Silencers for every source of process noise.

Application What the Silencer Does
Rotary PD Blower Intake Reduces intake pulses and smooths airflow into the blower
Rotary PD Blower Discharge Smooths discharge pulses to protect downstream equipment
Centrifugal Blowers Absorbs high frequency blade noise with acoustic material
Industrial Fans Controls noise without unacceptable back pressure
Compressor Bypass Vents Quiets excess air vented to keep compressors out of surge
Relief and Control Valves Quiets high pressure gas and steam venting
Dry Vacuum Pumps Silences the discharge and the jet port, with volume for low frequency pulses
Wet Vacuum Pumps Separator silencers remove free water and reduce discharge noise
Inlet Filtration Inline air filters, intake filters and intake filter silencers

Silencer Questions

Rotary positive displacement blowers take in and discharge air in large pulses. Intake silencers smooth the airflow into the blower, and discharge silencers smooth the pulses going into the piping, protecting downstream equipment and quieting operation.

Centrifugal blowers create high frequency noise from spinning blades. Their silencers absorb this noise using suitable acoustic material.

Fan silencers must control noise without creating unacceptable back pressure, because high back pressure lowers the fan efficiency.

Yes. Dry vacuum pumps need silencers on the discharge and jet port, and wet vacuum pumps use separator silencers that remove water from the air as well as reduce noise.

Yes. Inline air filters, intake air filters and intake filter silencers help protect blowers.
