7" Compact Plenum Exhaust Silencer

This pre-crimped ductwork fitting install between your fan blower's exhaust and the filter plenum to dampen air vibrations and reduce total system noise output by 3-6 dBa. Designed for use with our older 1HP-3HP Component dust collection systems.

Reduce Your Dust Collector's Noise Even Further

While nearly every Oneida Air Systems® dust collector includes our patented Drop-In Filter Silencers, we offer these industrial Plenum Exhaust Silencers for customers looking to reduce their system's noise output even further. Constructed from heavy galvanized steel, these components use acoustic dampening foam (shielded by an internal metal screen) to absorb the vibrating air expelled from the fan blower.

Both ends of the silencer are pre-crimped to facilitate installation into existing piping. Square-to-round adapters may be needed for installation with some OAS dust collection systems. Square plenum extensions are also available by phone order.
