ABAC ABC10-2312HP 10 HP Two-Stage Ironman Air Compressor - 120 Gallon Horizontal, 175 PSI, 32 CFM C2 Cast Iron Pump

The ABAC ABC10-2312HP pairs a 10 HP motor with the C2 two-stage cast iron pump on a 120 gallon horizontal ASME tank, delivering 32 CFM at a maximum 175 PSI. The horizontal layout sits low and long, 74 in end to end but only 50 in tall, which suits shops that would rather run the compressor along a wall or under a mezzanine than give up vertical footprint. This is a three-phase machine only. Choose 230V three-phase (ABC10-2312HP) or 460V three-phase (ABC10-43120HP).

Why a two-stage cast iron pump

The C2 is the cast iron pump ABAC builds the Ironman range around, and the second stage is what carries the air up to 175 PSI rather than the 125 to 135 PSI a shop is used to seeing from a lighter single-stage machine. Compressing in two steps with cooling in between means lower discharge temperatures per stage, and cast iron cylinders shed that heat and wear slowly instead of glazing. The practical result is a pump rated for heavy daily duty that can be serviced and rebuilt rather than replaced, which is the difference between a shop compressor and a consumable one.

What the 120 gallon horizontal tank changes

Storage is what keeps line pressure flat when several tools draw at once. A 120 gallon receiver gives the motor far fewer starts than an 80 gallon build on the same 32 CFM pump, and fewer starts means less heat, less contactor wear and steadier pressure at the drop. The horizontal layout spends that capacity on length instead of height: 74 in of wall and 50 in of clearance, against the 74 in of height a 120 gallon vertical needs. Plan for 728 lbs on the floor and check your door and ceiling clearance before delivery day.

How it compares

Same pump, same 32 CFM, different footprint. The ABC10-2312VP vertical build stands 74 in tall on a 30 x 41 in base and weighs 765 lbs, trading floor space for height. This horizontal unit runs 74 in long and only 50 in tall at 728 lbs, which is the one to pick under a mezzanine or a low ceiling. If you want the automatic tank drain, low oil level shut off and belt guard aftercooler fitted at the factory, the ABC10-23120HFF full feature horizontal is the same machine with the protection package already on it. If 32 CFM is already marginal, the ABC10-2312DHP duplex puts two 10 HP pumps on one 120 gallon tank for 64 CFM and lets you service one side while the other keeps air on the line.

Typical applications

Production shops, fabrication and welding bays, truck and fleet maintenance, tire shops running multiple lifts, and any operation where several air tools or a plasma cutter draw at the same time and the compressor needs to hold pressure through the shift rather than recover between jobs. ABAC rates the Ironman range for professional heavy duty work: hammering, grinding, orbital sanding, fastening, spraying, tire inflation and general equipment operation. At 32 CFM it will carry a pair of busy sanders or ratchets, a plasma cutter, or a blast cabinet in short sessions.

Installation and air treatment

Plan on a three-phase circuit sized to the motor nameplate and a disconnect within sight of the machine; there is no single-phase option in this frame size. Leave clearance around the flywheel and belt guard for cooling air and for belt service, and pipe the discharge with a flexible connector so vibration does not load the shop line. Oil, the air filter element and the belts are the routine service items. Where the air feeds paint, plasma or pneumatic controls, add a refrigerated dryer rated above the compressor's 32 CFM: the ABAC COOL 50 is rated 50 CFM and runs on standard 115V single-phase power, so it sits beside the compressor without new wiring. A coalescing filter downstream protects finishing work, and a condensate drain keeps the water the tank collects off your floor.

The 120 gallon reservoir cuts motor starts and holds a steadier line pressure than an 80 gallon build, while the horizontal tank keeps overall height down where ceiling clearance is tight.
