Downdraft Tables - Denray Machine, Inc.


Denray downdraft tables are ideal to help protect workers from hazardous smoke, fumes and particles generated during grinding, welding or sanding operations.  They are designed to pass the pollutants and sparks over water pans to protect the filters and reduce any fire risk.   Flame-retardant cartridge filters are standard. They are made of 100% spunbond polyester and remove particulate down to 0.5 micron with a 99.95% efficiency rate. Denray's "Jet Pulse" system cleans the filters using compressed air, dislodging the particles from the filters and into the collection drawer. The frequency of the cleaning can be controlled with the Jet Pulse's push button cleaning feature or an optional automatic timer. Other bag or cartridge filter systems are also available.   

The standard table top is a 1/4" steel plate. Strategically placed holes around the top's perimeter create a higher air flow near the spark shield and operator work area. A fiberglass grating is offered or rubber matting can be supplied for protecting polished products.   Denray Downdraft Tables are available from a 26" X 35" size, for small or single work cells, to their large 48" X 96" table. Additional options include mufflers, casters, auto-timers, HEPA and carbon filters.
