high performance
vacuum pumps
Congratulations on purchasing one of Robinair’s
top quality vacuum pumps. Your pump has been
engineered specifically for air conditioning and
refrigeration service, and is built with Robinair’s
proven offset rotary vane for fast, thorough
evacuation.
You’ll appreciate these key features . . .
Iso-Valve
TM
Allows the pump to be shut off while still connected to
the A/C-R system, which is handy for checking rate
of rise. With the valve handle in the OPEN position,
the pump is open to the system being evacuated.
In the CLOSE position, the pump is isolated from
the system. This minimizes pump oil pulled into
the pumping module, making start-up easier and
reducing wear and tear on the pump components.
High vacuum rating
The two-stage, offset rotary vane design provides
powerful, quiet, high vacuum capability and ensures
moisture removal, while the high pumping capacity
reduces evacuation time.
Lifetime filtration
The intake filter prevents foreign matter from entering
the pumping chamber, and an internal exhaust filter
separates oil vapor from the exhaust flow.
Directed exhaust
The exhaust is expelled through the handle to direct it
away from the service technician.
Gas ballast
A precise amount of atmospheric air is introduced
into the pump, preventing condensation of moisture
vapor and helping maintain the purity of the pump oil.
By using the gas ballast, the pump operates more
efficiently and pump life is extended.
Sure-grip handle
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.
Compact design
The pump measures approximately 40 cm long, while
aluminum housing and offset rotary vanes keep the
pump weight low, making it easy to carry.
For use on A/C-R systems
using CFCs, HCFCs and HFCs
in conjunction with mineral oil,
ester oil, alkylbenzene oil and
PAG oil as lubricants. Not for
use with ammonia or lithium
bromide systems. Not for use
with flammable refrigerants.
