Castair I71CUC2-S: 7.5 HP Single-Phase Industrial Compressor, Cube Pump, 35 CFM at 585 RPM
The Castair I71CUC2-S is a 7.5 horsepower, single-phase industrial reciprocating compressor with the cube pump (CUC) C2 configuration, running at 585 RPM and delivering 35.0 CFM free air. This is the higher-output, slower-speed cube pump option in the 7.5 HP single-phase lineup — delivering the same CFM output as the standard I718VC2-S and HC2-S models but in the cube pump physical format.
The 585 RPM pump speed makes this one of the quieter industrial compressors in the 7.5 HP class. Manufacturer specifications for the exact tank size, dimensions, and weight are not published on the Castair public product page for this specific model — contact us for confirmed specifications before ordering.
C2 Cube Pump Advantages
- Pump speed: 585 RPM — significantly quieter than the 895 RPM C1

- All cast iron construction: Long service life, heat-resistant, rebuildable
- Tapered roller bearings: Both ends of crankshaft
- Precision steel connecting rods: Automotive-type insert bearings
- Disc and spring valves: Efficient and serviceable
- 4-ring pistons: Better sealing, less oil carryover
- Centrifugal unloader: Loadless startup every cycle

I71CUC2-S vs. Standard I718VC2-S
Both units are 7.5 HP single-phase, C2 pump, 585 RPM, 35.0 CFM. The cube pump (CUC) format has a different pump head geometry than the standard cylindrical pump in the VC2 models. The I718VC2-S ships on an 80-gallon vertical ASME tank at 40x24x74 inches and 760 lbs. Call us to confirm the current tank and footprint configuration for the I71CUC2-S before ordering.
