• Various technologies for sound level reduction
  • Accommodation of a broad frequency range through a combination of different methods
  • Steel or stainless steel models
  • Horizontal or vertical mounting
  • Customised solutions available

Absorptive silencers

  • Usually cylindrical bodies lined with a porous attenuation material
  • Conversion of sound into thermal energy based on friction losses
  • Particularly suitable for the reduction of mid-range and high frequencies
  • Average insertion loss of 30 dB(A)
  • Special solutions available

Reflective silencers

  • Use of the sound reflection and expansion principles
  • Reflection and expansion by means of baffle walls, cross-sectional expansions and contractions
  • Increased exhaust gas back pressure, depending on the design 
  • Mainly attenuation of the low frequencies
  • Average insertion loss of 25 dB(A)
  • Special solutions available

Combined silencers

  • Combination of absorptive and reflective silencers
  • Mean insertion loss across the entire frequency range: > 40 dB(A)
  • Special solutions available
