Hilmor 1947970 3 CFM Vacuum Pump

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.

  • Hands-Free Carry – Two durable hoist points make transporting the vacuum pump easier. Compatible with the hilmor HVAC/R Carrying Strap.
  • Drains Oil Quickly – A sloped and channeled housing helps drain oil fast.
  • Quick, Easy Access – Easy access to a large oil fill port.
  • Easy To Check Oil – Quickly identify oil level and detect oil contamination through a large sight glass.
  • Extra Confidence – A blank-off valve isolates the pump from the system for accurate vacuum readings and easy oil change without losing a vacuum.
  • Prolong Oil Life – Gas ballast removes excess moisture extending the life of the oil.
