Liquid Water in Compressed Air
Service Line Water Vapor Condensation From
Cooling and Compression Occurs
Naturally Remove the water vapor from compressed air
prior to distribution through the air system.
Check operation of aftercooler and moisture
separator. Install a compressed air dryer sized
for the flow and dryness level required. (Note:
Filters may also be required to remove
particulates, liquid oil aerosols or for oil vapor
removal. Change cartridges as recommended
by the filter manufacturer.) Check all drain
traps routinely to insure their proper operation.
Maintain them regularly.
