Castair I7312HC2: 7.5 HP Three-Phase Industrial Air Compressor, 120-Gallon Horizontal Tank
The Castair I7312HC2 is a 7.5 horsepower, three-phase industrial reciprocating compressor on a 120-gallon horizontal ASME tank, C2 pump, without factory aftercooler. The aftercooler-equipped version is the I7312HC2-S.
The C2 pump runs at 585 RPM, delivering 35.0 CFM free air (28.1 CFM at 175 PSI). Three-phase motor operation provides more efficient, longer-lasting power delivery compared to single-phase equivalents. Unit weight is 820 lbs. Dimensions: 69x24x50 inches.

I7312HC2 vs. I7312HC2-S
The only difference is the aftercooler. The -S model includes the factory-mounted beltguard aftercooler (#BGAC1M, 35 CFM rated). If moisture control is needed, order the -S or add the aftercooler as a field-installed option. For general industrial applications where moisture handling is downstream, the base I7312HC2 is sufficient.
