Castair I1013HC2 — 10 HP Single-Phase Industrial Air Compressor, Horizontal Tank, C2 Pump
The Castair I1013HC2 is a 10 HP single-phase industrial air compressor with a horizontal ASME tank and Castair's two-stage cast iron C2 pump. This is the base configuration without a factory-mounted starter — your electrician supplies and installs the motor starter as part of the installation. The pump, tank, motor, belt guard, safety valve, pressure switch, and discharge tubing all ship factory-assembled.
Note on specifications: This model does not appear in Castair's standard published Industrial Series specification table. The exact tank capacity, pump RPM, CFM output, dimensions, and weight for this configuration were not confirmed at time of writing.

Cast Iron Pump Engineering — Why This Matters for Shop Longevity
Every Castair Industrial Series compressor is built around their oversized cast iron pump. Here is what separates these from lighter-duty machines:
- All cast iron construction — cylinder heads, crankcase, and cylinders are cast iron throughout. Cast iron manages heat better than aluminum and wears far more slowly under continuous load.
- Tapered roller bearings at both ends of the crankshaft — not ball bearings. Tapered rollers handle both radial and thrust loads simultaneously, which is exactly what a reciprocating pump crankshaft sees in operation.
- Precision steel connecting rods with automotive-type insert bearings — at both the crankshaft journal and the wrist pin. These are the same bearing design used in automotive engines. They are replaceable when worn — not a throwaway assembly.
- Disc and spring valves — simpler to service than reed valves, more efficient at high discharge pressures, and more reliable over years of cycling.
- 4-ring pistons — two extra rings versus typical 2-ring piston designs. Better compression sealing, significantly less oil carry-over into the air stream.
- Centrifugal unloader — the pump starts unloaded on every cycle without exception. This reduces motor starting current, reduces wear on the motor and belts, and eliminates the hard-start problem common in compressors that attempt to restart against pressure.
Tank, Motor, and Controls
- ASME-coded steel tank — powder-coated for corrosion resistance. ASME certification means the tank was designed and tested to a recognized pressure vessel standard, not just stamped with a number.
- ASME safety valve — factory-installed.
- Metal belt guard, totally enclosed — not a plastic cover.
- Copper discharge and unloader tubing or stainless-steel braided flex line — not plastic hose or rubber.
- Heavy-duty 1,725 RPM industrial motor with a minimum 15% service factor. This means the motor can sustain loads above its nameplate rating without tripping. In a shop where the compressor runs all day, the service factor is not a marketing number — it is the difference between a motor that lasts a decade and one that burns up in two years.
Who Buys the Non-Starter Version
- Facilities where the electrician prefers to source and install their own starter (matching existing panel brands, specific overload ratings)
- Shops adding this to an existing starter panel or motor control center
- Anyone who has a starter on hand from a previous installation
If you do not have a specific reason to skip the starter, order the I1013HC2-S (with mounted starter). Running a 10 HP motor without proper overload protection is how you destroy a motor.
