High Performance Vacuum Pumps
Congratulations on purchasing one of Robinair’s top quality
VacuMaster
®
vacuum pumps. Your pump has been engineered
specically for air conditioning and refrigeration service, and is
built for fast, thorough evacuation.
You’ll appreciate these key features . . .
The two-stage rotary vane design provides powerful, quiet, high
vacuum capability and ensures moisture removal, while the high
pumping capacity reduces evacuation time.
The intake screen prevents foreign matter from entering the
pumping chamber, and an internal exhaust lter separates oil
vapor from the exhaust ow.
The one-piece, molded handle makes it easy to carry the pump to
and from job sites, and the handle stays cool to the touch during
operation.
Aluminum housing and rotary vanes keep the pump weight low,
making it easy to carry.
