Axial Fans are installed with cylindrical silencers to reduce the sound to an acceptable level. Cylindrical silencers are commonly used as it can be connected directly to the round inlet or discharge side of a fan.

Rosenberg cylindrical silencers are available in two types:

• RS – open cylinder design;
• RSM – fitted with an concentric pod, producing better attenuation.

Three standard length of silencers are available:

• One diameter length: RSM-1D and RS-1D;
• One and half diameter length: RSM-1.5D and RS-1.5D
• Two diameter length: RSM-2D and RS-2D
