AIR-IN® NOISE REDUCTION CARTRIDGES

The Air-in® noise reduction cartridges have been designed to reduce noise in the exhaust and supply air ducts. Proven by tests, the noise reduction capacity of our cartridge is one of the best in the market (VTT).

The Air-In® noise reduction cartridge is the only noise reduction cartridge on the market that has been tested according to the noise requirements between flats by VTT Technical Research Centre of Finland.

Features

  • The Air-In® noise reduction cartridges are very easy to install and keep clean.
  • The Air-In® noise reduction cartridge is attached using the mounting ring at the end of the chain and pushed into the duct.
  • The Air-In® noise reduction cartridges fit supply and exhaust air ducts with a diameter of 100, 125 and 160 mm.
  • The cartridges do not cause pressure loss, so no changes are needed in the air conditioning of the flat.
