Downdraft tables or downdraught benches are workbenches with built-in ventilation to capture dust, smoke, and fumes and draw them away from the material being worked on. They typically consist of a perforated surface whose underside is connected to a ventilation or dust collection system, to draw material through the holes and away from the work. portable downdraft operation table,grinding downdraft table,down draft table Botou Ever Lucky Environmental Protection Machinery Co., LTD , https://www.dustcontrolling.com
