How do I remove moisture, dirt and oil from compressed air?
A. All compressed air systems will have condensed water, rust (scale) and dirt in the lines. To remove this contamination from the compressed air, a 5-micron filter separator with an automatic drain is provided with all Vortex A/C and Vortex Cooler systems. Properly maintained, these filters will ensure that only clean and dry, refrigerated air will enter the enclosure. A dryer usually is not required for proper operation, except when the normal relative humidity level is very high. A desiccant or refrigerated type dryer can be used in the inlet line to eliminate water vapor in the supply. The dryer should be rated to produce an atmospheric dew point lower than the output temperature of enclosure cooler. If upon start up of the compressor every day, large amounts of water are produced, a bulk water removal filter should be used upstream of the 5-micron filter. It is not necessary to supply lubricated air to a Vortex Cooler; in fact, excess oil and oil aerosols must be removed from the
