27 CFM (Rated for a 7.5 HP Compressor) Air-Cooled AfterCooler | VAN AIR AC-20-1

Air-Cooled Aftercoolers for your Compressed Air System

Compressed air discharged from an air compressor is hot and loaded with water vapor. An aftercooler reduces the amount of water in a compressed air system by lowering the temperature of the compressed air. The lower the compressed air temperature, the lower the amount of moisture it can hold.

In Van Air SystemsAC series air-cooled aftercoolers, hot compressed air is introduced to the core as ambient air is drawn across it, leaving the exiting air cooler. AC series after-coolers are normally sized for a 15°F (or less) approach to ambient air. For example, a compressor discharges 250°F air and the aftercooler is located in 80°F ambient conditions. With a 15°F approach, the air exiting the aftercooler will be 95°F and saturated, and the moisture created by cooling from 250°F to 95°F will condense.

Features and Benefits

• Horizontal or vertical flow directions
• Galvanized steel cabinet
• Open vented motor
• Pressure drop less than 3 psi at 80-125 psig

Sizing Instructions:

1.  Determine inlet temperature to aftercooler. 

2.  Determine desired outlet temperature. (Aftercooler outlet temperature = ambient temp. + approach)

3.  Determine needed approach. (Approach = desired outlet temp. - ambient temp.)

4.  Find flow (SCFM) under column of correct inlet and approach temperatures and read left for model number.
