ERMT = Elbow Film Lined Medium Velocity

Price Absorptive Film Lined Elbow Silencers are designed to provide a solution to undesirable noise in short runs of ductwork, with the added protection of a polymer film liner that encapsulates the acoustic media. This film liner protects the acoustic media from any moisture and airborne contaminants in the duct system. Price ERMT silencers are designed for a large range of velocity applications (2500 fpm or less). This configuration provides high levels of insertion loss across the full range of frequencies, and the sloped tail provides static regain for reduced pressure drop. These features, combined with Price’s ability to build each silencer to match the ductwork design, offer excellent flexibility to suit any application.

  • Polymer film liner encapsulates the acoustic media.
  • Acoustic stand-off separates the film liner from perforated metal to optimize insertion loss.
  • Improved mid-frequency performance.
  • The same engineered internal geometries used in the standard absorptive silencers that maximize insertion loss with reduced pressure drop.
