Blastrac 3-28DC dust collector has three motors and collects concrete dust in surface preperation jobs. Vacuum has resin-reinforced, pressure-molded plastic chassis and body. Motors and filter assembly are protected. Specially designed filter allows concrete dust to be dislodged by a manual shaker incorporated into the design. Pan capacity is 50 pounds, and a silencer keeps motor noise at 70 dBA.
