The DD 3'x4" downdraft table offers an automatic reverse pulse self cleaning system which will reduce maintenance and replacement filter cost. The system works by blowing compressed air through the filter in the reverse direction, dislodging smoke and dust from the filter. The solid pollutants are then collected in the dust drawer and must be emptied periodically. The self cleaning system is automatically activated each time the table is turned off. This downdraft table is suitable for collection of smoke and dust and comes complete with motor starter, cleaning controls, and silencer.
