The Castair I1033HC2 is a 10-horsepower, 3-phase industrial air compressor on a 30-gallon horizontal tank with the C2 pump configuration — without the factory-mounted magnetic motor starter. This is the non-starter variant of the I1033HC2-S, intended for installations where the motor starter is being sourced and installed separately, or where the electrical installation includes a remote starter panel. The 30-gallon horizontal tank makes this the most compact option in the 10HP 3-phase horizontal lineup, suited for tight spaces, service vehicles, or supplemental duty alongside a larger storage tank.
When to Choose This Version vs the -S Model
If your electrical installation already includes a properly rated magnetic motor starter for a 10HP 3-phase motor, or if your electrician is mounting a remote starter as part of the overall panel work, the non-starter version is the correct choice and avoids paying for a starter you already have. If you do not have a starter and your electrician is not supplying one, order the I1033HC2-S instead — running a 3-phase motor without a magnetic starter and overload protection is not safe and voids the warranty.
Pump Features
- All cast iron construction — cylinders, heads, crankcase. Castair builds their pumps to handle commercial daily-use loads for years.
- Slow RPM design — Castair industrial pumps run between 420 and 995 RPM depending on configuration. Lower RPM means lower operating temperatures and longer pump life.
- Tapered roller bearings at both ends of the crankshaft — handles thrust and radial loads correctly for long service life.
- Steel connecting rods with automotive-type insert bearings — at crankshaft and wrist pin. Insert bearings are replaceable for long-term serviceability.
- Disc and spring valves — reliable and serviceable in the field.
- 4-ring pistons — better sealing and less oil carry-over than 2-ring designs.
- Centrifugal unloader — motor starts under no load on every cycle.
Tank and Motor
- 30-gallon horizontal ASME-certified tank — powder coated with channel base.
- ASME safety valve — code compliant.
- 1725 RPM industrial motor — 15% service factor minimum.
- Totally enclosed metal belt guard.
- Copper discharge tube or stainless-steel braided flex line.
- Magnetic starter: NOT included — must be sourced and installed separately before operation.
