Both the air-cooled and water-cooled units require cooling air as well as air to the compressor inlet. Proper
ventilation MUST be provided; hot air must be exhausted from the compressor operating area. A typical
inlet-outlet air flow arrangement is shown in Figure 2-1.

Air-Cooled Units
- A combination oil/aftercooler is supplied as standard equipment on all air-cooled units.
The air-cooled unit with the standard enclosure requires sufficient flow, Figure 2-2, for the compressor
oil/after cooling system and for electric motor cooling. Air is drawn into the unit at the motor side of the
enclosure and is exhausted at the oil cooler side. Do not block the air flow to and from the unit. Allow three
and one-half (3-1/2) feet (1.1 M) to the nearest obstruction on the starter end and control box end of the
unit. Allow three (3-1/2) feet (1.1 M) to the nearest obstruction above and on other sides of unit. For
continuous efficiency, oil cooler cores must be periodically cleaned with either vacuum or compressed air.
If wet cleaning is required, shield motor and spray on a mild soap solution and flush with clean water.
