Noise Control Air Filtration Filtration Dictionary Universal Silencer Products for Air Moving Equipment Universal Silencer offers several absorptive silencer designs for air moving equipment, such as compressors, centrifugal blowers, and fans . As the 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. At frequencies above and below this range, attenuation performance progressively diminishes. Since the noise is absorbed by the packing media, the absorptive silencer does 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 that impose very little restriction to air flow.
All units are mild steel construction with primer-coated exterior.
The U5 Series is a premium, straight-through, absorptive silencer. It is especially well suited for inlet service on small rotary positive or centrifugal blowers or the discharge of vacuum pumps. The U5 is constructed of mild steel and has an enamel finish. The U2 Series is an economical straight-through silencer. The SU5 Series is our highest grade standard absorptive silencer.
