Type CAK

For the reduction of noise in plastic circular ducts for contaminated air

 

Plastic circular silencers for the reduction of noise in the circular ducts of extract air systems for aggressive media

  • 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/EG
  • 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 flame-resistant polypropylene (PPs) to DIN 4102, building class B1
  • Variant with spigot suitable for circular ducts according to DIN 8077 or DIN 8078
  • Insertion loss measured according to ISO 7235
  • Casing air leakage to EN 15727, class D


Optional equipment and accessories

  • With flanges on both ends
