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-21 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-21 is ideally suited for use with medium shot blasting, grinding, polishing and scarifying machines. For a safe, dust free and perfectly clean jobsite Blastrac has designed a full range of consumables and optional items to get the best possible results out of your dust collector and pre-separator.



Easy to manoeuvre and transport due to the robust wheels with brake systems. User friendly design, just connect the hose to the dust collector and you are ready to go.



Every Blastrac machine should be connected to a Blastrac industrial dust collector. This means that you are able to work dust free, creating a safe working environment.



Depending on the type of projects you are working on, you want to use a pre-separator that is most cost effective in the long term. Ask us for advice!



Limited downtime is essential for any successful job. Due to the special designs our medium dust collection systems allows you to change the bag quickly for limited downtime.



Our pre-separator, like any other Blastrac machine, do not use any chemicals or waste valuable drinking water. The pre-separator uses no electricity.



The up & down system makes it possible to lower the pres-separator so it will take up less space and fit into the back of a van.
