Air Compressor Line Cooler

This fellow measured his compressor outlet.

Air compressor line cooler.

Aftercoolers reduce the amount of water vapor in a compressed air system by condensing the water vapor into liquid form. They use either air or water and are an effective means of removing moisture from compressed air. Removing the liquid requires a moisture separator and a drain valve. Low cost air dryer water separator.

In a reciprocating air compressor for example the air temperature will drop anywhere from 50 degrees fahrenheit to 75 degrees fahrenheit across the roughly six inches of travel between the discharge port and discharge line. Post cooling all that water is still in the air line. Aftercooler system consisting of a b m model 70266 11 x 8 x 1 tranmission engine oil cooler an ebm pabst model w2e250 hl06 01 230v ac fan 1160 cfm in open air wired in parallell with the motor so when the motor runs the fan runs and a wilkerson model x01 04 m00 automatic drain. The compressed air travels through either the spiral finned tube coil or a plate fin coil design of the aftercooler while ambient air is forced over the cooler by a motor driven fan.

Air cooled aftercoolers use ambient air to cool the hot compressed air. Cooling condenses lots of water. Make no mistake a cooler alone does not yield high quality compressed air. Aftercoolers are heat exchangers for cooling the discharge from a air compressor.

The compressed air enters the air cooled aftercooler.
