CMX Silencers
Price CMX silencers are designed for medium velocity applications. This medium velocity configuration provides high levels of insertion loss across the full range of frequencies, and the sleek curved inlet and outlet of the center pod reduce turbulence and allows for static regain for improved pressure drop. This configuration is best suited for applications with velocities of 4000 fpm or less.

CHX Silencers
Price CHX silencers are designed for high velocity applications. This high velocity configuration has no parts that enter the air stream to constrict the airflow. The design minimizes the pressure drop that can occur at higher velocities while still providing high levels of insertion loss across the full rang of frequencies. The Price CHX Silencer model is best suited for applications where low pressure drops are the priority or high air velocities can not be avoided.

PRICE Absorptive Circular Extended Casing Silencers are designed to provide a practical solution for controlling duct noise in circular ductwork systems where high insertion loss is required at lower frequencies. This is accomplished by extending the outer shell to hold additional acoustic media without requiring changes to the sleek internal geometry utilized in the standard circular silencers. The design ensures maximum acoustical performance while minimizing system pressure drops at duct velocities as high as 8000 fpm. Our available standard sizes offer excellent flexibility to ductwork designs, and because we do not limit our cataloged silencer offering to certain sizes, we have the ability to build each silencer to suit the ductwork and, in turn, the application.

  • Eliminate costly square to round transitions.
  • Smooth aerodynamic internal geometries that minimize pressure drop and turbulence.
  • Highest quality leak free construction.
  • Capable of velocities as high as 8000 fpm.
  • 2" slip connection on both ends.
