Each compressed air system is typically composed of one or more compressors with a power source, control system, intake air filter, after cooler and separator, air receiver, air dryer, interconnecting piping and a distribution system to deliver air to points of application. Because the air leaving the compressor is generally saturated, any reduction in temperature will cause water to begin condensing...

Compressed air is often referred to as the fourth utility, and yet for an upstart business or process there is no commercial infrastructure that provides a core supply as exists with gas, electricity and water. When a need for compressed air is identified in planning and feasibility studies, it is necessary for the owners of the process or business to develop and maintain their own systems. Often the...

Compressed air is your most expensive utility. This is a fact that has been documented time and time again. It takes 7 to 8 hp of electricity to produce 1 hp in an airtool. In many plants, the compressed air system is the largest user of electricity. Yet, despite rising utility rates, compressed-air-system efficiency is frequently misunderstood or too often overlooked. Every plant or processing facility...
