Selecting the Right Size Pump
The more air a pump moves, the faster
it can reach an acceptable vacuum.
A smaller pump takes more time to
evacuate a system than one that’s the
correct size for the job.
Robinair pumps weigh less!
You’ll appreciate the difference a few
pounds make when you’re carrying
the pump up a ladder or through an
access hatch.
Robinair pumps use less oil!
Smaller oil capacity means that your
maintenance costs will be lower over
the life of the pump.

Premium High Vacuum
Pump Oil
The performance of your pump
depends largely on the quality and
purity of the vacuum pump oil.
Robinair’s oil is engineered to maintain
maximum viscosity at high running
temperatures and to improve cold
weather starts.
To keep the pump operating at peak
efficiency, change the oil frequently.
Moisture and other contaminants can
quickly deteriorate the purity of the
oil, thinning the oil, and reducing
the pump’s ability to reach deep
vacuum conditions.
Thermally Stable
Laboratory tests prove that Robinair oil
is more thermally stable in comparison
to other leading brands, which means
it resists breaking down due to heat
for a longer period of time.
Lower Moisture Content
Robinair oil has a lower moisture
content than other oils, thanks to
our special packaging and handling
procedures. Moisture degrades the
oil’s purity, thinning it, and reducing
the pump’s ability to reach a
deep vacuum.

Change Your Vacuum Pump
Oil Frequently
Clean oil is important for peak vacuum
pump performance. When the oil is
contaminated, it reduces your pump’s
ability to remove moisture from a
system. You should change the pump
oil frequently, and especially in the
following situations:
• You have just evacuated a system
that you suspect was overly
moisture-laden.
• You have just evacuated a system
with a compressor burnout.
• The pump oil looks cloudy or milky.
• The pump will not pull to factory
specifications when blanked off to an
electronic thermistor vacuum gauge.
• Every 10 hours of operation.

Iso-Valve™ – Isolates the pump from
the system with just a quarter-turn.
Gas Ballast – Moisture laden air
passing through the pump mixes with
relatively dry air so compression does
not cause condensation.
Two-stage Design – Cleans the
system more thoroughly than a single-
stage pump; the second stage starts
pumping at a lower pressure so you
can pull a deeper, ultimate vacuum.
Oil Drain Valve – Positioned at the
bottom of the oil reservoir and angled
for faster, more complete draining.

Oil Fill Port – Makes adding oil simple
since the port is accessible from the
front or either side. The sight glass on
the front of the pump shows you when
enough oil has been added.
Heavy-Duty Motor – High torque
design for easy startup and efficient
operation.
Offset Rotary Vanes – Our proven
design builds a powerful compression
within the pumping chamber to
reduce system pressure and vaporize
moisture so it can be exhausted along
with air.
Molded Base – Durable polycarbonate
base improves pump balance and
minimizes vibration during operation.
Die-Cast Aluminum Housing – Cast
aluminum housings make the pumps
lightweight but durable.
The Importance of
Measuring Vacuum
Moisture in an A/C system is a serious
problem for the technician – it causes
freeze-ups and corrosion, seriously damaging
the A/C system. The most effective way to
eliminate moisture is to create a vacuum
deep enough
to boil it away. For that, you need a high
vacuum pump, and a tool to tell you when
the vacuum is deep enough to adequately
dehydrate the system.
Without a means of measurement, evacuation
time is based on guesswork. The length
of time required for thorough dehydration
will vary from system to system because
of several factors – so using a clock isn’t
foolproof. You risk not removing all the
moisture – or wasting time by running the
pump long after evacuation is complete.
Many service technicians rely on the
compound gauge of the manifold to read
vacuum. While the manifold is good for gross
measurements, it’s simply not accurate
enough to determine exact vacuum levels.
It’s designed to read low pressures in inches
of mercury, but there’s no way to read exact
levels when you’re pulling the last, most
critical inch of vacuum.
If you look at the compound gauge face,
you can see that it’s not possible to clearly
differentiate between 29" Hg and 29.9" Hg,
for example. But in microns – the precise
measurements for the last inch of vacuum –
that’s the difference between roughly 23,000
and 250 microns.
A closed-end, U-tube, mercury manometer is
capable of reading to 500 microns. However,
it’s a delicate instrument, more suited to a
laboratory or controlled environment.
The most economical, effective, and easy-
to-use option is an electronic thermistor
vacuum gauge. It eliminates the guesswork
by measuring the vacuum to precise micron
levels, ensuring the system is leak-free,
moisture-free, and ready to be recharged.
Although originally developed as a laboratory
instrument, today’s thermistor vacuum
gauges are rugged enough – and reliable
enough – for field service work.
Tests done under the same laboratory
conditions confirm that Robinair
vacuum pumps consistently out
perform other major brands. Our
Model 15600 reaches a vacuum of
600 microns in just 60 minutes, while
the competition’s pumps took more
than two hours to reach the same
micron level.
