MAXIMUM CAPACITY (SCFM)
Rated capacities are based on the following conditions: Inlet and approach temperature at inlet pressures 80 to 125 PSIG.
Approach Temperature: The number of degrees above the temperature of the cooling medium (in this case ambient air) to
which the aftercooler reduces the compressed air. A higher approach does not mean better performance.
