Now available from Vollmer is the new VFS 400 filtration system, which simultaneously enables the ultra-fine filtration of cooling oil or dielectric fluid from up to two of the company’s sharpening machines for circular saws, or to a VHybrid 260 grinding and erosion machine.

The purity of cooling oil or dielectric fluid is critical in the manufacture of cutting tools. It enhances the sharpness of the cutting edges on drills, milling cutters and reamers, while improving precision and surface finish. Furthermore, well-maintained fluid quality prolongs the service life of the machine and its peripheral equipment.

The VFS 400 can filter out particles up to 5 µm in size. It pumps contaminated cooling oil or dielectric fluid out of the sharpening machine before feeding into the dirt tank via a pre-filter. The reusable pre-filter ensures the main filter enjoys an especially long operating life. A filter pump feeds the cooling oil from the dirt tank to the ultra-fine filtration system. Solids are separated from the liquid in two or optionally four filter units with small filter elements, where each element has a waste capacity of around 3.5 kg.

The clean tank can optionally feature a cooling system to set the oil or dielectric fluid to the optimal operating temperature. The filtration capacity when running with two filters is 50 l/min, while with four filters it is 100 l/min. VFS 400 systems have a drainage outlet opening and a fill level indicator with automatic fill level monitoring that simplifies maintenance. In addition, the flow rate indicator reports any necessary filter changes are reported to the user.
