Backed by the PRAB Difference

 
 

Significantly Lower Your Operational Costs

Operation:

The coolant is pumped from the machining center or grinder to the center of the drum via a distribution trough. The drum is lined with a non-woven filter media. The liquid then flows through the media, removing particles in suspension, and discharges through the bottom of the unit into a sump or tank. As the media blinds off and the coolant level rises to a predetermined level in the drum, a sensor activates the media advance mechanism, rotating the drum and exposing new media.
