All access fine-finishing Downdraft Table

We have a wide variety of Downdraft Booths and Tables for grinding, sanding and fine finishing.

Tube Filtration

Model 2872

Tube filters are ideal for applications involving finishes and fine sanding dust. Life expectancy of the tube filters is between 1-2 years with average use. The dust is captured inside the tube and falls from the filters into the dust drawer below, when the machine is turned off.

A soft bristled brush (furnished with all tube filtration models) is used to run inside the filters, offering a deep cleaning procedure for the filters if needed. The tube filters clean at a 99% capture rate at 1 micron, creating a much superior filtration than any pleated filters.


Ideal for small shops and labs. With complete access to the work surface from all 4 sides and built in power supplies for 110V hand tools. Filters are usually good for up to two years and can be reordered by simply giving us a call. All models are available in 110V or 230/460 three-phase. Available up to 48"x96”. Made entirely in the USA.
