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 air compressors supplied with an associated refrigerated or desiccant dryer is an excellent choice for supplemental or temporary source of clean and 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 to be below 60 degrees F, – 40 degree desiccant dryer can be utilized to ensure the 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.


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. 


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 requiements emerge that AirNow Fleet of Oil-Free rental compressors can be a quick and economical source of temporary or supplemental compressed air.
