The Busch Mink MM Series vacuum pump is a newly designed, compact version of the proven Busch Mink MI pressure/vacuum pump. It is especially designed for all applications where dust particles may be present. Vacuum is provided by two non-contacting, claw-type rotors in an oil-free chamber. It is single-stage and reaches an end vacuum of 37.5 torr. Because of the noncontacting design, there is no wear in the pumping chamber, which results in very low maintenance. The high volumetric efficiency and no-friction pumping chamber creates significant savings in electrical power.
