Downdraft Tables are dual-purpose workbenches and extraction units, designed for the collection and purification of smoke fume and dust at the source. Power extraction motor offering 3300CFM air volume for 20% backdraft extraction and 80% downdraft. It is a great solution for welding, grinding, and plasma cutting for small to medium size parts.
The worker has free, open operation over the worktable surface, and gravity works with the blower to pull contaminants into the bottom dust collection drawer, away from the breathing zone. Benches are used for composite dust, fiberglass dust, marble dust, metal particulates, and welding smoke.

1. Intelligent control and backflush control system, efficient and safe.
2. The text display screen intuitively shows the operating status.
3. Button operation, simple and convenient.
4. Fault alarm function.
Fully automatic pulse jet cleaning (0.1~0.3s) using compressed air. The air enters the filter cartridge and expands rapidly, causing impact vibration to shake dust into the collection bin.
1. Flame-retardant PTFE coated polyester fiber filter element with 0.3-micron accuracy.
2. Filtration efficiency over 99.9%.
3. Service life: 3000~4000 hours.
Replaceable surfaces for carbon steel, stainless steel, brass, nylon, etc. Optional rotating table and combined downdraft + side draft function.
Aluminum alloy housing and explosion-proof glass for safety. Cold light source prevents stroboscopic radiation and reduces visual fatigue.
Standard pin-hinged foldable wings help direct airflow efficiently and accommodate parts of varying sizes.
