The DV-CM4 Chip-Master Vacuums are a powerful addtion to serious machine shops. These units can gulp up and separate chips from coolant, then pump filtered coolant back into your machine tools or coolant storage. Each unit features an internal chip collection basket to trap metal shavings down to 0.05" (1.3mm). A second filtration through the polypropylene filter will trap metal fines down to 300 microns. The built-in transfer pump can then be used to return the filtered coolant to the machine tool or into collection drums.
