Lube Oil Contamination in Compressors

Blowby,a term refering to compress gasses/air, force passed piston rings, contain moisture which condense into, and water-log the oil. Solution: 1-Install a ventilation tube/system to work in such a way as to flush a gallon of moisture laden air out of the crankcase every minute. 2-Add an oil heating element to the crankcase. This spark plug size device would heat the oil driving off moisture.3-Add Mega Power Oil Treatment to reduce blowby,avoid oil breakdown. http://www.megapowerinc.com/

The auto drains you mention are generally after the fact. Your problem is in the Air intake. High humidity in your location? Refrigeration dehumidication is my vocation. Your compressors may be getting a little tired if blow-by is excessive. You also will see some oil carry-over, you didn't mention that. You may be able to design an air scrubber to dehumidify the inlet air. A lot depends on location, location. Del www.co-engineering.net

I agree with the comment about drying your air intake. Also, since you state that you are running three compressors in parallel, if you do not use check valves on each output and/or individual reservoirs (each with its own check valve) on the outputs, you could be blowing wet compressed air back into the compressors, unless you have managed to synchronize the pistons somehow (very unlikely). While one compressor is on its compression stroke the other(s) might be taking in air. If only one check valve is used on a central reservoir the three compressors feed each other where they are tied together.

Of course, I could be all wet on this! (grin)
