Compressed Air Challenge
Compressed air is considered industry's fourth utility, but is seldom considered as a contributing cost of production. Instead, compressed air costs are typically blended into overhead and often thought of as "free." Such ambiguity can hide cost savings that can positively impact your bottom-line and affect your ability to account for production costs. Do you know your actual cost for producing compressed air?

Formula to calculate the cost of compressed air:
BHP x .746 x hours x electric rate/Motor Efficiency
Conversion of scfm to acfm:
Where:
Ps = Standard pressure, psia (CAGI & ISO use 14.5 psia)
Pa = Atmospheric pressure, psia
ppm = Partial pressure of moisture at atmospheric temperature
RH = Relative humidity
Ta = Atmospheric Temperature, °F
Ts = Standard Temperature, °F (CAGI and ISO use 68 °F)
(CAGI and ISO standard is at zero RH)
Compressed Air and Gas Institute (CAGI)
Since 1915, the Compressed Air and Gas Institute (CAGI) has been the leading organization representing manufacturers of compressed air system equipment, including air compressors, blowers, pneumatic tools and air and gas drying and filtration equipment. For over 80 years, the Institute has been working to improve production, proper use and increased distribution of equipment used in compressed air and gas systems. Read More...

Benefits and Applications of Compressed Air
Compressed air is a safe and reliable power source that is widely used throughout industry. In fact, approximately 70% of all companies use compressed air for some aspect of their operations. Unlike the other utilities, compressed air is generated on-site, giving users much more control over usage and air quality. Read More...
