SU5 12″ Absorptive Blower Silencers
The SU5 series is the highest grade standard annular flow absorptive silencer. They are well suited for inlet service on small rotary positive displacement blowers (where discharge P < 15 psig) or the discharge of vacuum pumps.
The high length to diameter ratio provides better noise attenuation for high frequency noise sources. The U5 and SU5 series have similar attenuation characteristics:
This 12″ blower silencer is constructed from mild steel, with enamel paint. The design consists of two concentric perforated cylinders lined with acoustical pack, forming an annular flow path. This design features full blocked-line-of-sight, while providing full flow area for low resistance.

Absorptive Blower Silencers
The absorptive type silencer is the classic dissipative design, deriving its noise control properties from the basic fact that noise energy is effectively “absorbed” by various types of fibrous packing materials. More technically, as sound waves pass through the spaces between the tightly-packed small diameter fibers of the absorptive material, the resulting viscous friction dissipates the sound energy as small amounts of heat.
Absorptive silencers are very effective on high frequency noise (500-8,000 Hz). At frequencies above and below this range, attenuation performance progressively diminishes.
Since noise is absorbed by the packing media, absorptive silencers do not rely on internal baffles, tubes or other restrictive devices to achieve noise reduction. Consequently, absorptive silencers generally employ “straight-through” or similar internal designs which impose very little air flow restriction.
