The atmospheric air that surrounds us is contaminated with varying concentrations of hydrocarbons, solid particles and water vapor. When compressed to a working pressure of 100 PSIG, the concentration of these contaminants is increased by a factor of 8:1 (eight to one). If these contaminants are not removed prior to entering a process distribution system they will damage air operated equipment, slow down or stop production, corrode the inside of pipes, spoil product, ruin processes, and drive up energy costs.

There are three major contaminants

Moisture is a serious problem in compressed air systems. Since atmospheric air always contains some amount of moisture, measured in terms of relative humidity, it will enter the intake of a compressor and at 100 psig, the concentration will be increased by a ratio of 8 to 1.

Particulate matter consists of atmospheric particles that are drawn into a plant piping system through the air compressor intake. Some air system components, along with scale build-up in piping, may introduce additional particulate matter.  Particulates traveling through the air system will cause pressure drop to increase, valves and orifices to clog, and product to be spoiled.

Airborne hydrocarbons, compressor oils and lubricants are harmful to all downstream equipment and processes. Today’s high performance compressor lubricants can cause additional problems, and need to be removed before they cause irreversible damage. They will cause valve and gasket materials to fail, and wreak havoc on processing equipment.
