AirComParts EC10H12 10 HP Two-Stage Air Compressor - 120 Gallon Horizontal, 175 PSI, 33-35 CFM, EC10 Pump

The AirComParts EC10H12 is a 10 HP two-stage reciprocating air compressor on a 120 gallon horizontal ASME tank, built around the ACS EC10 cast iron pump. This is the size most shops land on when a 5 HP machine stops keeping up: sustained 175 PSI air for multiple bays, a plasma table, a sandblast cabinet, or a production line running more than one tool at a time.

Two-stage compression runs the air through a low-pressure cylinder, an intercooler and then a high-pressure cylinder, so the pump holds a full 175 PSI without the heat a single-stage pump builds getting there. The EC10 is a slow-speed pump at 700 RPM with steel rods and inserted bearings, which is what keeps a machine of this duty rebuildable rather than disposable.

Key specifications

• Horsepower: 10 HP
• Pump: EC10, two-stage, belt driven, cast iron, 700 RPM slow speed
• Delivery: 33.4 CFM at 175 PSI on single phase, 35 CFM at 175 PSI on three phase
• Maximum pressure: 175 PSI
• Tank: 120 gallon horizontal, ASME coded, made in the USA, supplied with safety valve and drain valve
• Weight: 1,090 lb. Add approximately 100 lb for crated shipping weight
• Available power: 230V single phase, or 208V, 230V and 460V three phase
• Motor frame: the EC10 pump is matched to a 215T frame motor
• Pump features: steel rods with inserts, positive ring-fed lubrication, centrifugal unloading
• Belt guard: all metal

Choosing your configuration

• Basic Unit includes the pump, belt guard, ASME tank and electric motor. It does not include the motor starter, which an industrial motor requires for proper cycling.
• With Starter Unit adds a motor starter, mounted and wired ready for use.
• Package Unit adds the mounted motor starter plus a beltguard-mounted aftercooler and an automatic tank drain.

At 10 HP the aftercooler stops being a nice-to-have. A machine moving 35 CFM pushes a lot of water into the tank and down the line, and the aftercooler on the Package Unit removes roughly 75 percent of that moisture before it ever reaches the tank. The automatic tank drain then discharges what does condense, which protects the tank and keeps full air storage available instead of slowly filling it with water.

Why the three-phase Basic Unit covers two voltages

The 230V and 460V three-phase Basic Units share one part number, E1014, because the motor is dual-voltage 230/460V and the starter, which is the component that fixes the supply voltage, is not part of a Basic Unit. The 208V three-phase Basic Unit, E10148, is a separate part number. On the With Starter and Package configurations every voltage has its own part number because the starter is matched to the supply.

A note on single phase at 10 HP

The 230V single-phase version is available and delivers 33.4 CFM, slightly under the three-phase figure. If you have three-phase service, use it: the motor is cheaper to run, the starting current is far lower, and at this horsepower single phase asks a lot of a typical shop service. If three phase is not available, the single-phase unit is a real option, but have an electrician confirm your service before ordering.

Typical applications

Multi-bay automotive and truck service, body and paint shops, plasma and laser cutting tables, sandblast cabinets, CNC machining, woodworking shops, tire service, and general plant air where a steady 175 PSI supply has to feed several tools at once.

Options we can add

Beltguard-mounted aftercoolers, special electrical enclosures, TEFC or explosion-proof motors, special voltages and starter configurations, a low-range 30 to 40 PSI pressure switch, and dryers, filters, regulators or coalescers. These units are built to order, so talk to us before you buy if you need the package configured a particular way.

The AirComParts EC10H12 pairs a 10 HP motor with a 175 PSI two-stage EC10 pump and a 120 gallon horizontal ASME tank, in Basic, With Starter and full Package configurations across 230V single-phase and 208/230/460V three-phase. Tell us your supply and the tools you are running and the Warthog Air Compressor Store team will size it with you.
