The compressed air industry is taking a step that will clear the air about the performance of its equipment. For the first time, many compressed air equipment manufacturers will submit their 50 hp to 200 hp lubricated rotary-screw compressors and 200 cfm to 1,000 cfm refrigerated air dryers to an independent laboratory for performance testing.
Carefully managing compressed air can save money. Compressed air is often overlooked in energy studies because many people do not fully understand compressed air equipment, their own system, or what it costs to produce compressed air power.

Chemical processors face significant challenges in controlling fugitive emissions. The emissions escape from valves, compressors, pumps, piping components, etc. It is a difficult task, but necessary to avoid penalties and other liability.
Anywhere compressed air can be eliminated represents an opportunity to reduce system operating expenses. Often, this reduction means fewer compressors must operate to meet the plant's air requirements.

Electric variable-speed drives on lubricant-cooled and lubricant-free rotary air compressors are not a cure-all for system woes -- chemical plants must implement them correctly and at the right time to achieve maximum energy savings
