Process air and gas silencers are used to help manage noise associated with air and gas movement in industrial process systems.
These silencers are typically associated with rotary blade and centrifugal blower applications where process airflow or gas movement can create elevated sound levels.
Available in application-dependent absorptive silencer designs, process air and gas silencers may be configured for different structural requirements, ranging from lighter welded construction to heavier welded construction where required by the project.

Depending on the acoustic requirements of the system, designs may include features such as an absorptive outer layer or a central acoustic pod. Certain configurations may also incorporate aerodynamic design elements to help manage system pressure loss.
Process Controls Corporation (PCC) can assist customers in evaluating process air and gas silencer requirements for industrial applications. Contact PCC for more information about available silencer options, application considerations, and product selection support.
