Air-cooled compressed air after-coolers, available as electrically or pneumatically operated models, cool the compressed air with atmospheric air.
The compressed air is cooled to approximately 90 C above the ambeint temperature. This causes the oil and water vapour to condense which is then removed by the seperator. Water cooled after coolers are also available.
After coolers of various capacities from 1M3/min to 25 M3/min are available. The recommended aftercooler to be used on 750cfm compressor will be the 25 M3/min
