POOL: Type CS


TROX circular silencers type CS are intended for use in room air conditioning systems.

In air distribution systems they can be used to attenuate fan noise and to reduce the air-regenerated noise of air terminal units.

To avoid sound transmission through ventilation ducting between adjacent rooms they can be integrated into the duct system as so called cross talk silencers.

  • Circular silencer in rigid construction
  • Outer casing and perforated inner duct are aluminium
  • Lining is mineral wool conforming to DIN 4102, fire rating class A2, with RAL quality mark RAL-GZ 388
  • Mineral wool faced with fibreglass as protection against erosion suitable for air velocities up to 20 m/s
  • Insertion loss tested according to DIN EN ISO 7235

The outer casing and perforated inner duct of circular silencers Type CS are aluminium.
The non-combustible acoustic material is available in insulation thicknesses of 25 mm or 50 mm.
