Coolant filter delivers extra-fine filtration

The patented STAR Filter® from Eriez⪚ HydroFlow® uses a centrifugal pump to draw liquid through a permanent media element with an optional feed of cellulose filter-aid for extra-fine filtration. It typically is installed as a central system with flow rates of more than 250 GPM and filtration to 1 micron.

Each interchangeable element can be removed for inspection and reinstalled without concern for misalignment or improper sealing. Individual panels are positioned to provide a vertical drop to dislodge the filter cake, which allows a gentle yet thorough settling of the vacuum-compressed filter cake.

The element’s star shape and the filter panel’s compact rectangular design maintain structural integrity after removal from the filter. With the end caps removed, cleaning on both sides of the filter panels is simplified.
