Allied Group manufacturers intake and discharge silencers and mufflers for blowers, compressors, engines, vacuum pumps, air motors, pneumatic equipment, fans and any other application that requires reduced noise level.We offer several absorptive silencer sizes for air moving equipment. These silencers contain fibrous packing materials that control noise by "absorbing" noise energy. 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.Absorptive silencers are highly effective on high-frequency noise (500-8000 Hz). 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.

We manufacture 2 types of mufflers; Sintered Mufflers/Silencers and Allied Witan Replacement Mufflers:
