SAVD • Sound attenuation volume dampers

  • Regulating damper
  • Sound attenuating

Sound attenuating volume control dampers in polyurethane foam

Application

  • For air regulation and acoustic attenuation in ventilation and airconditioning systems
  • To be inserted easily into round ducts with low sound generation even at large pressure drops
  • Pressure and airflow are easily adjustable by varying the number of open holes of the damper
  • Multiple dampers can be used to obtain higher acoustic attenuation

Material

  • Damper mainly made out of flexible polyurethane foam with very good damping abilities and flameresistance tested according FMVSS-302, the fabric flammability standard, wich is also the standard used in e.g. the automotive industry. Fire resistance class B (Equivalent to M1)
  • Cut-out holes with parts that can easily be taken out to adjust air volumes
  • Anti-bacterial anti-fungus foam mousse
  • Rot-free

Colour

  • Black coverage at one end and mixed-colored polyurethane foam

Mounting

  • To be inserted in circular ducts of Ø80, Ø100, Ø125, Ø160, Ø200, Ø250 and Ø315
  • Dampers for ducts in Ø315 available upon request
  • To be mounted at at least 50-350 mm distance A between the duct opening and first SAVD damper when used in air supply
  • To be mounted at at least 0-50 mm distance A between the duct opening and the first SAVD damper when used for exhaust of air
  • To be mounted at a minimum distance B in between 2 dampers at at least 250 mm in air supply and 150 mm in air exhaust when multiple dampers are mounted
