1.Connect the plenum to the fan / blower outlet with the bolts provided. Band clamp tube filters to the Ring Thimbles on the bottom of the plenum and to the tops of the 5 gal. buckets.

(Check mounting height - Match to bag heights)

Build your own plenum

Plenum box can be constructed of plywood or metal. Oneida Air Systems sells 22 gauge galv. plenum boxes. The filter medium is a 16 ounce polyester felt which has been singed inside to help release caked dust.

For the tube style filters, a 12” dia. ring thimble (Part # FAZ000000) is needed for each filter. The plenum box and the ring thimbles are suspended above the floor at a height that will allow for a 5 gallon plastic bucket and tube filter to fit properly underneath.

A well sealed plywood box will make a good plenum for air distribution through the tube filters. Use plywood for the plenums. Cut 12” dia. holes in the bottom of the box (spaced 2 - 3” apart), so that the ring thimbles fit snugly. The rings should not be able to slide through the holes. Bend Ring Thimble tabs then apply duct sealant or caulk around the edge of the ring thimble. Use sheet metal screws to secure. Be sure to remove any sharp edges from the bucket or ring thimble that may abrade the filter. Slide the filter over the thimble past the raised bead. Secure with a band clamp. Slide the bottom of the filter over a five gallon plastic bucket. Secure with a band clamp or strong bungee (shock cord). Be sure filter is not loose or moving around when the system

is on. This could lead to wear on the filter.

With the use of a cyclone pre-separator, the buckets will not need emptying very often, but do need to be checked occasionally. Simply lift the bucket, the weight will indicate how full the bucket has become.

Note: Plenum hole configuration varies. The number of holes matches the number of filters.

5 & 7.5 HP Direct Drive Cyclonic Dust Collectors specifications

Oneida Air Systems is a recognized leader in the field of dust collection technology, offering a range of powerful solutions for both professional woodworkers and serious DIY enthusiasts. Among their impressive lineup, the 5 HP and 7.5 HP Direct Drive Cyclonic Dust Collectors stand out for their exceptional performance and engineering.

These dust collectors are designed to efficiently capture and remove airborne dust and debris generated during woodworking and industrial processes, promoting a cleaner and safer work environment. One of the primary features of these units is their direct drive motor system. Unlike traditional belt-driven models, the direct drive technology provides a more compact design with fewer moving parts, resulting in increased reliability and reduced maintenance.

Another key characteristic of the Oneida 5 HP and 7.5 HP models is their cyclonic separation design. This innovative technology allows for the effective separation of fine dust particles from larger debris. The cyclonic action creates a vortex that forces heavier particles downward into a collection drum, preventing clogging in the filter system. This not only enhances the efficiency of the dust collection process but also extends the lifespan of the filter by significantly reducing the amount of dust that reaches it.

Both models are equipped with powerful industrial-grade motors that deliver impressive airflow capabilities. The 5 HP unit provides approximately 1,800 CFM, while the 7.5 HP model exceeds 2,700 CFM, making them ideal for handling multiple machines connected via ductwork. Furthermore, these collectors feature dynamic impeller designs that maximize suction while minimizing noise levels, making them suitable for use in a variety of workshop environments.

User-friendly features such as quick-release collection containers and integrated caster wheels for easy mobility add to the practicality of these systems. The Oneida Air Systems dust collectors also come with a range of accessories, including ducting, blast gates, and HEPA filter options, allowing users to customize their setup according to their specific needs.

In summary, Oneida Air Systems’ 5 HP and 7.5 HP Direct Drive Cyclonic Dust Collectors offer unparalleled performance, innovative technology, and user-centric design. They are engineered to meet the demands of serious woodworkers and industrial applications, ensuring a cleaner workshop and a safer working environment. With their robust construction and efficient dust collection capabilities, these models are an investment in quality that pays off in both productivity and health.
