Thanks to a compact design and low operating cost, the HSF Suction Belt Filtration System has become a global market leader for gear grinding applications. Fitted with a custom-made continuous filter belt, the HSF is able to achieve a superior level of filtration while maintaining a steady supply of coolant to your machine tool.
During the filtration process, coolant is drawn through the filter belt. The particulates are captured on the surface of the filter belt while clean coolant is able to flow through the belt and into the clean tank, from where it is cycled back into the machine tool. The particulates form a filter cake, which is also an aid in the filtration process. After a defined differential pressure is reached, the filter automatically regenerates by briefly breaking the vacuum and advances the filter belt. The filter cake advances forward with the belt to the drying station before being discarded into the chip cart. A cleaning brush and rinsing system clean the belt at the discharge. The filtration capacity exceeds the required supply, which means the clean tank always has enough coolant to allow a continuous supply to the machine tool with no downtime.
