Your days of messing around with clunky, unreliable pumps are over. The first thing you ll notice is how two durable hoist points allow you to transport your vacuum pump with ease. Simply attach the hilmor HVAC/R Carrying Strap, throw it over your shoulder and get to work. Several innovative features also help make changing oil easier. The front of the pump where the oil is stored is sloped downwards, creating a natural path for oil to drain faster. An oversized sight glass allows oil to be checked easier and an oversized oil fill port makes pouring in new oil easier. These vacuum pumps have been retooled to make evacuation as easy as possible.
