The Castair I518HC2-S is a 5HP single-phase industrial air compressor with the larger C2 horizontal tank and a factory-mounted magnetic starter. In the 18-series lineup, the HC2 gives you more stored air volume than the HC1 configuration — useful when your shop runs multiple air tools at the same time or when you need to minimize how often the compressor cycles. Single-phase power keeps it compatible with shops that have not upgraded to three-phase electrical service.
