Compressor Short Cycling

Short cycling means the compressor starts and stops, or loads and unloads, much more often than it should. It wears out motors, starters, contactors, and valves, and it wastes power. The usual root cause is too little storage or a control band that is too tight.

High Discharge Temperature

A compressor that runs hot or trips on high temperature is telling you it cannot get rid of its heat. Remember that most of the electricity a compressor uses becomes heat. The Compressed Air Challenge puts it at as much as 80 to 93 percent. When that heat has nowhere to go, the machine shuts itself down, or the oil and parts break down early.

Oil Carryover

Oil showing up downstream is an expensive problem. It ruins paint jobs, contaminates product, swells some seals, and fouls dryers and filters. First find out where the oil is coming from. Sometimes it is the compressor. Sometimes it is a lubricator someone turned all the way up.

Wet Air in the Lines

Water in the air lines is the most common air-quality call you will get. Nine times out of ten the fix is something that drains or dries, and it is already installed. Start there before you quote a new dryer.
