AirComParts K7V8 7.5 HP Two-Stage Air Compressor - 80 Gallon Vertical, 175 PSI, 23-25.5 CFM, 452 Kellogg-Equivalent Pump

The AirComParts K7V8 is a 7.5 HP two-stage reciprocating air compressor on an 80 gallon vertical ASME tank, driven by the 452 pump that cross-references to the Kellogg-American 452. The 452 is the larger of the two pump castings offered at 7.5 HP, and it is the same pump fitted to the 10 HP K10V12 and K10H12 units, so a shop standardising on one pump family across several machines can stock a single set of valves, rings and gaskets.

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 vertical tank puts 80 gallons of storage into roughly a quarter of the floor space a horizontal unit needs.

Key specifications

• Horsepower: 7.5 HP
• Pump: 452, two-stage, belt driven, Kellogg-American 452 equivalent
• Delivery: 23 CFM at 175 PSI on single phase, 25.5 CFM at 175 PSI on three phase
• Maximum pressure: 175 PSI
• Tank: 80 gallon vertical, ASME coded, made in the USA, supplied with safety valve and drain valve
• Weight: 825 lb. Add approximately 100 lb for crated shipping weight
• Available power: 230V single phase, or 208V, 230V and 460V three phase
• 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.

The aftercooler on the Package Unit cools the discharge air and removes roughly 75 percent of its moisture before it reaches the tank. The automatic tank drain discharges condensate on its own, protecting the tank and keeping full air storage available.

K7V8 or K7ZV8?

Both are 7.5 HP on an 80 gallon vertical tank. The K7V8 carries the 452 pump, delivers 23 CFM single phase or 25.5 CFM three phase, and weighs 825 lb. The K7ZV8 carries the Z332 pump, delivers 26 CFM, and weighs 639 lb. Pick the 452 unit if you want the larger pump casting or want to match an existing 452 machine; pick the Z332 unit if flow per pound and a lighter install matter more.

Why the three-phase Basic Unit covers two voltages

The 230V and 460V three-phase Basic Units share one part number, K1535, 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 three-phase Basic Unit, K15358, is a separate part number.

The AirComParts K7V8 pairs a 7.5 HP motor with a 175 PSI two-stage 452 pump and an 80 gallon vertical ASME tank, in Basic, With Starter and full Package configurations across 230V single-phase and 208/230/460V three-phase.
