This product is designed for use with Oneida Air dust collectors with an external 18" diameter cartridge filter that is attached via J-Bolts to the plenum elbow; this includes all Super Dust Gorilla, Pro Series, Dust Gorilla Pro, and Direct Drive dust collectors manufactured after 2012. If you have an older system with a filter that is secured to the plenum via a threaded rod running through the center of the filter stack, you will need to purchase an additional 17" threaded rod length and a coupler (available at any local hardware store) to provide enough room to attach the Stacking Sound Filter. Please Note: This item is not designed for our High Vacuum systems, items #XXK050133 and #XXK050333, as there is not enough room to attach the sound filter when the system is mounted to the standard leg kit. Please refer to the 18" compact sound filter instead (item #BSS181000).
Yes; If you have room underneath the filter assembly (varies by model) then you can stack multiple sound filters, however, the resulting noise reduction per filter is not linear (additive) and is subject to diminishing returns. For example: 1 Sound Filter = 6-7 dBA total reduction 2 Sound Filters = ~9 dBA total reduction 3 Sound Filters = ~10 dBA total reduction 4+ Sound Filters = ~10 dBA total reduction
Both the Stacking Sound Filter and the Exhaust Silencer offer similar performance in terms of noise reduction, but exhaust silencers must be installed into the plenum assembly and will increase the overall footprint of the system by 12" to 36" and will require additional components (hangers, square to rounds, etc.). Exhaust Silencers are intended for installation into long transitional ducting such as when the filter is located far from the collector - typical of industrial systems such as the Direct Drive. Comparatively, the Stacking Sound Filters can be installed quickly and easily, requiring no additional components.
