Castair I713HC1: 7 HP Single-Phase Industrial Air Compressor, Horizontal Tank
The Castair I713HC1 is a 7 horsepower, single-phase industrial reciprocating air compressor on a horizontal ASME tank, C1 pump configuration, without the factory-mounted motor starter. This is the base configuration of the I713 horizontal series — the motor starter is field-installed separately, which gives your electrician full control over the starter specification and panel location.
The horizontal tank suits shops where ceiling clearance is limited or where a lower-profile unit integrates better into the shop layout. Like all Castair industrial series compressors, this unit is built around an all cast iron pump running at slow RPM — the design philosophy that separates industrial-grade equipment from the high-speed consumer units that wear out in a few years of shop service.
Who This Compressor Is For
- Shops with an electrician handling the motor starter installation separately
- Installations where the starter panel needs to be remote from the compressor
- Buyers who want industrial cast iron pump quality at the base price point
- Shops with horizontal layout requirements or limited ceiling height
Industrial Cast Iron Pump Construction
- All cast iron construction: Cylinder, head, and crankcase — cast iron throughout
- Slow pump RPM: Low RPM operation for quiet running and extended pump life
- Tapered roller bearings: Both ends of crankshaft for superior load support
- Precision steel connecting rods: Automotive-type rod insert bearings at crankshaft, bearings at wrist pin
- Disc and spring valves: More serviceable and reliable than reed valves under industrial duty cycles
- 4-ring pistons: Better sealing and reduced oil carryover compared to 2-ring designs
- Centrifugal unloader: Loadless start every cycle — protects motor and pump at startup
Tank, Motor, and Controls
- Tank type: Horizontal ASME-rated tank with channel base
- Powder-coated finish: Corrosion-resistant powder coat on tank
- Motor: 7 HP single-phase, 1725 RPM industrial motor, 15% service factor or higher
- Voltage: 230V single-phase
- Motor starter: Not included — field-installed separately (see I713HC1-S for factory starter version)
- ASME safety valve: Factory installed
- Belt guard: Metal, totally enclosed
I713HC1 vs. I713HC1-S: Which Do You Need?
The only difference between these two models is the motor starter:
- I713HC1 (this unit): No factory starter — you source and install the starter separately. Choose this if your electrician specifies the starter, if the starter is being mounted in a panel away from the compressor, or if you are replacing a compressor on an existing starter.
- I713HC1-S: Factory-mounted magnetic motor starter included and wired at the factory. Choose this for the fastest installation with a properly matched starter.
Available Configurations in the 7 HP Single-Phase Lineup
- I713HC1 (this unit) — 7 HP, 1-phase, horizontal tank, pump C1, no starter
- I713HC1-S — Same, with factory-mounted magnetic starter
- I713HC2 — 7 HP, 1-phase, horizontal tank, pump C2 configuration
- I713HC2-2 — 7 HP, 1-phase, horizontal tank, pump C2 variant
