Type CA

For the reduction of noise in circular ducts, galvanised sheet steel construction

Circular silencers Type CA for the reduction of noise in the circular ducts of air conditioning systems

  • Absorption material is non-combustible mineral wool with RAL quality mark, biosoluble and hence hygienically safe according to the German TRGS 905 (Technical Rules for Hazardous Substances) and EU directive 97/69/EC
  • Mineral wool faced with non-woven glass fibre as protection against erosion due to airflow velocities up to 20 m/s
  • Casing and perforated inner duct are galvanised sheet steel
  • Variant with spigot has a groove for a lip seal, suitable for circular connecting ducts to EN 1506 or EN 13180
  • Insertion loss measured according to ISO 7235
  • Casing air leakage to EN 15727, class B

Optional equipment and accessories

  • With flanges on both ends
  • With lip seals on both ends
