ERMTX Silencers
Price ERMTX film lined absorptive extended casing silencers are designed for a large range of velocity applications. This medium velocity configuration provides high levels of insertion loss across the full range of frequencies, and the sloped tail arrangement allows for static regain for improved pressure drop. This configuration is best suited for applications with duct velocities of 2500 fpm or less.

Casing Medium Velocity


Price Absorptive Film Lined Elbow Silencers are designed with baffles that extend past the standard casing, and target low frequency noise. Similar to the ERMT, the extended model attenuates undesirable noise in short runs of ductwork, with the added protection of a thin polymer film liner that encapsulates the acoustic media. This film liner protects the acoustic media from moisture and airborne contaminants that may be present in the duct system. A minimal system pressure drop is maintained by utilizing the same internal design of the standard absorptive silencers. These features, combined with Price’s ability to build each silencer to match the ductwork design, offer excellent flexibility to suit any application.

  • A thin polymer film liner that encapsulates the acoustic media for added protection.
  • Acoustic standoff that separate the film liner from the perforated metal to ensure the highest levels of insertion loss.
  • Larger baffles that target difficult low frequency duct noise.
  • Improved mid frequency performance provided by a 90 degree bend.
  • The same engineered internal geometries that are used in the standard absorptive silencers to maximize insertion loss and minimize pressure drop.
