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.   

NUCLEAR DOME TESTING

An interesting application for the AirNow Compression Services C-18 Trailer Mounted Centac is nuclear power plant containment dome testing.  By Federal Regulation, all nuclear containment domes must be leak rate tested before commissioning and then three times during the next ten years.  This is accomplished by pressurizing the dome with oil free air to one half its rated pressures or 12-60 PSIG, depending upon design.  The Nuclear Regulatory Commission is currently trying to change the regulation to full pressure.  The decay of pressure is measured and the leak rate calculated.  The volume of the domes involved varies from 250,000 cubic feet for a boiling water reactor to 3 million cubic feet for a large pressurized water reactor.

Soot Blowing

Air soot blowing in coal fired power generating plants is an important application. In most cases the power plant is on the verge of shutdown if a failure of the permanent soot blowing compressors is experienced.  AirNow Compression Services have assisted many coal-fired power plants in such emergencies
