If you get a compressor with a filtration system or add filtration to a compressor that was acquired with out it, there are some things you should know. Every compressor manufacturer that provides filtration with their machine, advertises a capacity for that filtration. There is also some FINE print that says something like "at standard inlet conditions". Standard Inlet Conditions refer to the gas temperature when it leaves the final separator. Generally, this inlet temperature for an air cooled, reciprocating compressor is 15 F above the ambient operating temperature. If a manufacturer uses an inlet temperature of 68 F when referring to the processing capacity of their filtration, this means that the ambient operating temperature would have to be 53 F to get the full rated capacity. Operating in temperatures above the "standard" reduces the processing capacity. Why, you may ask? The answer is that higher temperature air holds more moisture. The descecant chemical (usually a molecular seive) controls the life of the filtration (whether you use cartridges or repack). The greater the moisture content of the gas entering the filter, the faster the descecant is used up, resulting in shorter filter life.
