Proven to Improve Surface Finish by an Average of 27%
Small-Footprint Solution for Solids Filtration
PRAB Drum-Type Filters occupy one-third of the floor space of a traditional paper bed filter, saving valuable work space in your facility. Filtered fluid can be reused, lowering your operational costs.
Top Features & Benefits:
Can be used for both ferrous and non-ferrous metals
Disposable paper filter media is available in a variety of grades to meet your specific requirements
Filter media surface is automatically indexed only when needed
Automatic self-cleaning and self-monitoring system
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.
