Fan sound levels can often be reduced to required criteria by fitting of acoustic attenuators, these silencers are for use in all air movement applications and especially for both “on fan” and “in duct” application.

Two types are available – CA which is a “straight through” design and CPA – which is with additional concentric pod for higher noise attenuation.

Standard short length silencers are coded CA-1D and CPA-1D. Double length silencers, CA-2D and CPA-2D, give increased attenuation at all frequencies or for low air velocities. Both types are available in a wide range of sizes and flanged for direct attachment with our ventilation fans.
