The Robinair VacuMaster vacuum pump has an 8 cfm rating, which makes it ideal for work on larger capacity a/c systems, says the company. It features a 1-hp thermally protected motor, 18.6 oz. (550ml) oil capacity, and vacuum rating of 40 microns. The ergonomic handle grip with closed handle offers technicians balance and portability. Its inlet fitting allows maximum airflow while preventing oil backflow and its finned surfaces dissipate heat faster, keeping the pump cooler.
