These compact units offer stable pressure and high-precision filtration in tool-in-tool coolant applications. By providing the necessary pressure and filtration accuracy, they improve machining quality and extend tool life. Coolant, drawn from a central system or independent tanks, is passed through high pressure pumps and precision filtration units and delivered into the tool at the desired pressure. The filtration level is configured to protect sensitive such as the spindle and rotary joint, and the system operates fully automatically
