BTH-B2E • Rectangular sound attenuators express

  • Rectangular
  • Galvanised steel
  • Mineral wool + resonance plates
  • Delivery within a week

Standard rectangular sound attenuators with a fixed length of 1000 mm.

Delivery possible within a week.

Application

  • BTH-B2E silencers are designed to reduce sound generated from fans and airconditioning devices with maximum sound attenuation in the 250Hz octave band. The sound attenuation performance of the BTH-B2 silencers with build-in B2 attenuation splitters are superior to classical absorption attenuators on frequencies of 63 to 500 Hz with equal length and width of splitters and equal splitter pattern pitch. In other frequency bands the BTH-B2 silencers are also well adapted to ventilation and air-conditioning system acoustic requirements

  • Silencers with Splitter thickness d=100mm is suitable for smaller air flow rates as well as in the case where high degree attenuation is required in the high frequency range.
  • Standard version silencers with cellulose foil or galvanized steel sheet plates are suitable for velocities up to 20m/s between the splitters

Composition

  • The attenuation housing is made of galvanized sheet steel which complies with air tightness class C (ATC3)
  • Splitters with frames of galvanized steel and fillings with highly efficient absorption material are build into the housing
  • Filling exposed surface is protected with cellulose foil
  • They are designed to be incombustible class A1, Euroclass DIN EN 13501-1
  • B2 splitters are partly covered with galvanized steel strips
  • Strips of galvanized sheet steel or cellulose foil run along the splitter length L
  • The B2 splitter height en length are not interchangeable. The splitter L dimension shall always run in the direction of the propagation of sound
