This pre-separator can triple the lifetime of the filters because it captures 80-90% of dust. It also prevents reduction in the suction performance of the dust collector. The Blastrac BPS-LP-0021 is equipped with a Longopac bagging system, which is easy to mount and handle. Thanks to this system, the operators have no more contact with the dust in their direct vicinity. The BPS-LP-0021 is ideally suited for use with medium shot blasting, grinding, polishing and scarifying machines.
