Down Draft Tables. Sometimes the best solution for extracting welding fumes is right on the table.This is generally referred to as a Down Draft Table. The Downdraft Table serves as both a workbench and an air cleaner.
A rigid grill supports the product, while an air cleaner below draws smoke and fumes down and away from the worker's breathing zone. A worker can weld, grind, and cut on the surface of the table while dust and fumes get sucked away from breathing air space
Some important points to consider when purchasing:
What is the velocity or the air required to pull the fumes and dust downward into the table (Capture Velocity)? (Add up the CFM for all of the inlets that will run at once)
What is velocity at the Table surface required to achieve the appropriate Capture velocity (Face velocity)?
Do I have enough filter media (Air to cloth ratio) in the collector?
Will it stand up to the working environment (Eg: is it made from Plastic or Steel?)
Filter cleaning: Does the filter cleaning system really work in your application?
What will be my filter, maintenance and energy costs per year?
Are there any tertiary risks such as fire, explosion, etc, that I need to consider?

pre-engineered downdraft table complete with 1 Clean 2® 150 ft2 cartridge filter, integrated fan with TEFC direct drive class II motor and external dust tray generating 800 CFM with 150 FPM downdraft velocity. The DTH-800 draws contaminants away from workers’ breathing zone without hindering movement making these tables an ideal solutions for most welding and light dust/smoke applications.
The DTH-1700 is a Self-Contained pre-engineered Down Draft table comes complete with an integrated Fan and filtration system in addition to it's 24"D X 48"W work surface and 18" tall removable side & back shields generating 1400 CFM with 208 FPM downdraft velocity. The DTH-1700 draws contaminants away from workers’ breathing zone without hindering movement; large work area meets range of applications. Its use of (2) CLEAN-2 cartridge filters and the manual VIBRA-PULSE filter cleaning system makes this unit the ideal solution for most welding and light dust/smoke applications.
The DT3000 is a completely self-contained pre-engineered Downdraft table. Comes complete with an integrated 3HP or 5HP energy saving blower, high efficiency cartridge filters and automatic self-cleaning system. Available in 2 standard sizes: 66" X 42" or 96 X 42" work surfaces at heights of 33".
The DT3000 draws contaminants away from workers’ breathing zone without hindering movement; and allowing the workers to work/walk around all sides of the table. The DT-3000 uses (6) CLEAN-2 ULTRA high efficiency cartridge filters (150 SQ. FT. of media each / 900 SQ. FT. total) and the VIBRA-PULSE filter cleaning system allows those filters to be cleaned in place when they become saturated. All you have to do is activated the cleaning system and empty the tray.
One of 2 powerful fan/motor combinations generate between 3000 and 4500 CFM.
This solution is ideal for most welding, Grinding and cutting applications.
Downdraft table that Meets NFPA 651 for processing and finishing aluminum when properly used and maintained.
Integral Collection Area and Work Surface Draws contaminants away from workers' breathing zone without hindering movement, open work area meets range of applications
