Made in Mount Vernon, MO.  Denray produces a series of all metal dust control solutions from downdraft tables, to sanding booths, to overhead ambient air scrubbers. Denray’s self-powered down draft table and dust booths are an industry standard. The many models available range from a tube filtration system which cleans with a 99% capture rate at 1 micron to cartridge filters and jet pulse cleaning capable of capturing particles as small as .5 microns at 99.95% rate. Specialty tables equipped with optional HEPA filters for control of toxic dust, fumes or smoke, charcoal filters for odors, chimneys and mufflers for controlling and lowering decibel level of exhaust air
