AIR COMPRESSOR GUIDE
Available from Kaeser Compressors, Inc., a guide to understanding and measuring the complete cost of generating compressed air, often referred to as "the fourth utility." The guide demonstrates that in 125 hp applications, the annual cost of electrical power to drive compressors can be twice the cost of the compressor unit. Over a typical 10-year period, a compressor that cost $40,000 can accumulate up to $800,000 in electrical power costs. The guide explains the various factors that affect efficiency in the compressed air system, and outlines easy steps to dramatically increase the efficiency of existing systems.
