The Educt-O-Matic is the compact hand-portable closed-circuit blast tool, which can be transported everywhere and required just 2.5m3/min of air at 6bar. Blasting and media recovery are controlled just with one trigger. Media recovery is initiated by slightly pulling the trigger, while pulling the trigger fully starts the suction blast system. Abrasive is stored in a compact conical hopper fromwhere it is metered into the blast apparatus. Abrasive is drawn into the mixing chamber of the Educt-O-Matic by the high speed airstream, where it is mixed with air, and is then propelled out of the nozzle. The blast head is adjustable and swivels to allows blasting at any angle. Abrasive and dust are captured in the rubber attachment. Reusable abrasive is drawn back to the hopper, whereas broken abrasive and dust are directed to the dust bag. An area about 30mm wide can easily be cleaned with an Educt-O-Matic. When finished with blasting, just release the trigger to half-way for two to three seconds, and the vacuum recovers the remaining dust and abrasive Blast System: Suction Blast 1-1/2 cups capacity Closed-circuit Blast Head: Rubber containment with 3/8-inch suction blast nozzle and 3/16-inch suction jet Construction: Steel and aluminum body Power Requirements Electrical Air Consumption: No electric required 90 cfm @ 90 psi Dimensions: 26" h X 12" w X 11" d Shipping Weight: 12 lbs (1 cardboard carton) I sent a pdf that of a Educt-O-Matic of another ind.
