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.
