Circular silencers for the reduction of noise in circular ducts of ventilation and air conditioning systems

Circular silencer made of galvanised sheet steel or stainless steel

  • Attenuation effect due to absorption
  • The sound absorbing material is non-combustible mineral wool and non-hazardous to health according to the German TRGS 905 (Technical Rules for Hazardous Substances) and EU directive 97/69/EC
  • Acoustic data measured to ISO 7235
  • Leakage class C or D (depending on size) to EN 15727.
  • For use in areas with potentially explosive atmospheres (according to EC Directive 2014/34/EU (ATEX)), zones 1, 2, and zones 21 and 22 (outside) according to EC Directive 1999/92/EC

Optional equipment and accessories

  • Spigot with lip seal, for circular connecting ducts to EN 1506 or EN 13180
  • Socket-type spigot suitable for circular ducts to EN 1506 or EN 13180

General information

Application

  • Circular silencer for the reduction of noise
  • For the reduction of air-regenerated noise of air terminal units LVC, TVR, TVE and of mechanical self-powered controllers RN and VFC
  • For the reduction of fan noise
  • Can be used as cross talk silencer to reduce the transfer of noise through ducts between neighbouring rooms

Special features
