The Castair I533HC2-S pairs the larger C2 horizontal tank with a 5HP three-phase motor and factory-mounted magnetic starter. In the three-phase horizontal lineup, this is the configuration for shops that need both the efficiency advantages of three-phase power and the extra stored air volume the larger tank provides. More stored volume means fewer compressor cycles during peak demand, which reduces wear on the motor and pump over time.

HC1 vs. HC2 on Three-Phase: Which Do You Need?
The HC1 and HC2 use the same 5HP three-phase motor and cast iron pump. The difference is receiver tank size. If your shop has enough compressor on time vs. air demand with an HC1, the HC1 is sufficient. If you find the compressor cycling too frequently or if you run multiple high-demand tools simultaneously, the HC2 tank gives you more buffer before the pressure drops enough to trigger another cycle.
What This Compressor Handles
- High-demand body and auto shops with three-phase power looking to minimize compressor cycling
- Multi-bay facilities running several air tools and spray equipment simultaneously
- Fleet service centers with sustained compressed air demand throughout the shift
