Castair I713HC2: 7 HP Single-Phase Industrial Air Compressor, Horizontal Tank, C2 Pump
The Castair I713HC2 is a 7 horsepower, single-phase industrial reciprocating compressor on a horizontal ASME tank, equipped with the C2 pump configuration. The C2 designation in the Castair industrial series indicates a larger, slower-speed pump compared to the C1 — the C2 runs at lower RPM, which means quieter operation and longer pump life at the cost of a slightly larger footprint and higher unit weight.
This is the base horizontal C2 model without a factory-mounted starter. Like all Castair industrial units, the pump is all cast iron and designed for continuous shop service rather than the intermittent duty cycles that consumer and prosumer compressors are rated for.
C2 vs. C1 Pump: Why It Matters
In the Castair industrial lineup, the pump configuration number indicates the pump size and speed:
- C1 pump (I713HC1): Runs at higher RPM — lighter unit, smaller footprint, lower price point. Good for moderate-demand shops.
- C2 pump (I713HC2, this unit): Runs at lower RPM with a larger pump displacement. Quieter, runs cooler, tends to last longer under continuous load. Better for shops with higher duty cycles or where noise is a concern.
For reference, in the well-documented 7.5 HP lineup: the C1 runs at 895 RPM and delivers 32.4 CFM at 0 PSI, while the C2 runs at 585 RPM and delivers 35.0 CFM at 0 PSI despite the lower RPM — because the C2 pump has larger cylinder displacement.
