SPCDD
PDC-XP2000 Downdraft Table

HEPA Downdraft Tables and Fume Extractors. Made in the USA, PDC Portable Downdraft Benches are engineered for effective, economical control of dry dusts, fume and smoke that is generated from sanding, polishing, grinding and more. 

Spare parts and replacement filters are easy to order. 

Ideal for light to moderate concentrations of dry contaminants, the Downdraft Benches draw fumes, vapors, smoke and particulate down and back-away from the operator’s breathing zone. 

Elimination of Hexavalent Chromium from Stainless Dust

Highly efficient cartridge filters trap particulate down to .5 microns, while pulse-jet compressed air blasts keep filters clear and operating at optimum efficiency. The HEPA after-filter is efficient to .3 micron @99.97%. 

74 dBA noise level at 2 meters. 

Stainless can off-gas a carcinogenic dust in the form of hexavalent chromium

Stainless can off-gas a carcinogenic dust in the form of hexavalent chromium.  The compact Downdraft and Backdraft feature a 24" x 24" x 12" HEPA filter, and a primary filtering cartridge of up to 295 sq ft of filter surface area.

There is an Optional Carbon Cell for VOC

There is an optional carbon cell for VOC. It is a 24" x 24" x 12" stack that bolts on to the exhaust. It can take a pair of 28 lb cells containing a range of 4mm absorption medias, from activated carbon, the Alhhasorb8, and others. 

Hinged side panels and adjustable slots are standard. The Backdraft Hood is 36" Wide. 

Enclosed Hood for Better Source-Capture

Enclosed Hood for better Source-Capture is very important if you have a lot of cross airflow from fans or other equipment.  This enclosure means you can capture more particulate by creating a dedicated capture zone. The sides are hinged for easy access when working on larger pieces.
