INSTRUMENT QUALITY AIR – Oil Free is Preferred
The Instrument Society of America
definition of "Instrument Quality" Air is:
-
A maximum oil content of less than one
part per million (by weight);
-
The particle size in the air stream
must be less than 40 microns; and
-
The dew point must be 18ºF below the
minimum temperature to which the air is exposed
AirNow oil free centrifugal compressors
supplied with an associated refrigerated or desiccant
dryer is an excellent choice for supplemental or
temporary source of clean dry instrument quality
compressed air. It should be noted that +40 degree
dewpoint refrigerated dryers can be employed where
ambient conditions are expected to be above 60 degrees
F. Where ambient temperatures are expected below 60
degrees F, – 40 degree desiccant dryer can be utilized
to ensure air being supplied meets or exceeds Instrument
Air standard in low ambient operating conditions.
Instrument air quality is required in
pneumatic process control systems, laboratories, powder
coating, spray painting, packaging machines, automated
production equipment ect.
PLANT
AIR
The
extensive use of compressed air in industry is second
only to the use of water. This air is used for tools,
forges, hoists, conveyors, instruments and a host of
other uses in the 100-125 PSIG range. Needless to say,
the loss of a plant’s compressed air supply can put a
manufacturing facility completely out of production.
This is where the AirNow Fleet of Oil-Free high capacity
rental compressors takes over. AirNow only rents the
inherently oil-free Ingersoll-Rand CENTAC centrifugal
plant air compressors, sizes ranging from 1,800 to over
21,000 CFM. We can normally have the equipment on the
way within 24 hours of a call. Our skid mounted units
require only power hook-up, cooling water, a small
amount of control air to start, and a discharge line to
carry the compressed air to the plant system.
For
example, a large Midwest foundry experienced a major
explosion in their plant air system severely damaging
the compressor house and shutting down the foundry. The
AirNow Compressor Fleet received the call at 4 p.m. for
five (5) C-25’s. The first two compressors arrived the
next day. Twenty-four hours after the call all five
Centacs were on site and one was running! Of course,
AirNow cannot always promise this rapid service, but it
is a good example of the effort we put into serving our
customers’ needs in times of emergency.
AirNow
Compression Services has supplied plant air to
refineries, glass plants, automobile assembly plants,
appliance manufacturers and electric utilities just to
name a few.
WIND
TUNNEL & JET ENGINE TEST STAND
Throughout the U.S.A., there are large numbers of wind
tunnel facilities operated by universities, aircraft,
missile, and spacecraft manufacturers and by various
Government and private research companies. Wind tunnels
are either the blown down or continuous blow type. They
are sub-sonic, super-sonic, tri-sonic, etc. tunnels that
can vary flow or velocity, temperature, humidity, and
altitude to simulate various test conditions. Jet
engine test stands similarly can be computer programmed
to simulate varying speeds, ambient conditions,
altitude, etc., and record the data. Most wind tunnels
have large trains of centrifugal or axial compressor
installations, usually motor-gear driven.
There
are times that these compressor facilities have
breakdowns or short term special test requirements
emerge that AirNow Fleet of Oil-Free rental compressors
can be a quick and economical source of temporary or
supplemental compressed air.
