This unit is designed for facilities that have a preferred starter supplier, are integrating this compressor into an existing control panel, or are purchasing for an installation where the electrical contractor will be supplying and sizing the starter separately. At $9,825.75, it occupies a practical middle position in the 25 HP tandem range between the single-voltage starter-included HC2-S and the 3-phase large-tank HC3-S.\u003c\/p\u003e\n\n\u003cp\u003e\u003cem\u003eNote: Manufacturer specifications for this model are pending — contact us at 866-217-0063 for confirmed CFM output, tank capacity, dimensions, and wiring requirements before ordering.

At 25 HP, a properly rated starter is mandatory — not optional — for safe and code-compliant operation.
