AirComParts K15H123 15 HP Two-Stage Air Compressor - 120 Gallon Horizontal, 175 PSI, 55 CFM, 462 Kellogg-Equivalent Pump, 3-Phase

The AirComParts K15H123 is a 15 HP three-phase two-stage reciprocating air compressor on a 120 gallon horizontal ASME tank, driven by the 462 pump that cross-references to the Kellogg-American 462. At 55 CFM delivered at 175 PSI it is a plant-air machine, sized for continuous production rather than intermittent shop work: multiple blast cabinets, pneumatic presses, automated lines and large paint operations.

Two-stage compression squeezes the air twice, with an intercooler between the low-pressure and high-pressure cylinders, so the pump reaches a full 175 PSI without the heat and wear a single-stage pump takes to get there. The horizontal tank keeps overall height down under a mezzanine or an overhead crane.

Key specifications

• Horsepower: 15 HP
• Pump: 462, two-stage, belt driven, Kellogg-American 462 equivalent
• Delivery: 55 CFM at 175 PSI
• Maximum pressure: 175 PSI
• Tank: 120 gallon horizontal, ASME coded, made in the USA, supplied with safety valve and drain valve
• Weight: 1,677 lb. Add approximately 200 lb for crated shipping weight
• Available power: 208V, 230V or 460V, three phase only
• Low oil switch: included as standard on every 15 to 25 HP K-Series unit
• 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 15 HP a machine pushing 55 CFM also pushes a great deal of water into the system. The aftercooler on the Package Unit cools the discharge air and removes roughly 75 percent of its moisture before it reaches the tank, and the automatic tank drain clears the condensate that does collect without anyone having to remember to crack the drain valve. If you are feeding a refrigerated dryer downstream, the aftercooler is what keeps the dryer inside its rated inlet temperature.

Low oil protection

Every 15 to 25 HP K-Series unit carries a low oil switch as standard equipment. On a pump this size a dry crankcase is a scrapped pump, so the switch is the single most valuable piece of protection on the machine.

Why the three-phase Basic Unit covers two voltages

The 230V and 460V Basic Units share one part number, K2014, because the motor is dual-voltage 230/460V and the starter, which fixes the supply voltage, is not part of a Basic Unit. The 208V Basic Unit, K20148, 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.

The AirComParts K15H123 pairs a 15 HP three-phase motor with a 175 PSI two-stage 462 pump and a 120 gallon horizontal ASME tank, in Basic, With Starter and full Package configurations at 208V, 230V and 460V.
