Type CAK


TROX circular silencers type CAK made of PPs plastic, are intended for use in room air conditioning systems subject to aggressive media.

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.
