<p>PURPOSE:To attain dried compressed air by a method wherein the primary passage of an after-warmer is conduced to the lubrication oil piping system between the receiver tank and oil cooler and the secondary passage of the after- warmer, is conduced to the compressed air piping system after passing through the after-cooler. CONSTITUTION:To obtain dried compression air by communicating the primary flow path of an after-warmer 6 to a lubricant pipe system between a receiver tank 3 and an oil cooler 7 while communicating the secondary flow path of after warmer 6 to the piping system of compressed air after passing the aftercooler 6. Consequently compressed air saturated when passing through the aftercooler 7 is heatexchanged with waste heat of lubricant to produce dry compressed air. Since the lubricant piping system between the receiver tank 3 and oil cooler 7 and compression piping system after passing through the aftercooler 6 are arranged heat exchangably, the delivery air temperature will never drop in the receiver tank 3 to produce dry compressed air without causing emulsification of lubricant in said tank 3.</p> |
