Robinair 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 CLOSED 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.
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.
The intake filter prevents foreign matter from entering the pumping
chamber, and an internal exhaust filter separates oil vapor from the
exhaust flow.
Exhaust is expelled through the handle to direct it away from the service
technician.
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.
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.
The pump measures 40 centimeters long, while aluminum housing and
offset rotary vanes keep the pump weight low, making it easy to carry.
