Coolant Filtration. Simplified.
The patented Chip Disc Filtration (CDF) technology achieves high levels of filtration without two separate belts. Our patented disc design provides a direct coolant flow path into the coolant reservoir and can filter a wide variety of materials, both in water and oil based coolant, down to 25 microns nominal.
This affordable, versatile approach to chip removal is Hennig designed and patent protected. It is the most simple approach to coolantfiltration in the market today. The Hennig CDF system is simple by design, and can be used with a scraper type belt or a hinge belt.
Cast Iron Filtration. Made Easy.
For the notoriously difficult cast iron applications, the addition of a solid rotating magnetic drum can be incorporated for efficient removal of floating chips, fines and sludge.

- Continuous Self-Cleaning Operation
- Continuous spraying of filtered coolant against the stainless steel media removes fines & chips. No outside source such as air or steam is used.
