Compressed Air AOL

The AOL Series utilizes forced ambient air to cool compressor lube oil and is an excellent choice for demanding oil cooler requirements or for converting medium to large volume water cooled compressors to air cooled.  The design features rugged brazed aluminum bar and plate construction with detachable legs for ease of mounting in alternate locations.  This cooler is ideal for rotary screw, compressor lube or gear box oils.  The series includes nine models with oil flow capacities from 15-120 GPM (57-454 LPM) to be used on compressors from 35-400 HP (26.1-298.3 KW).
