ABAC AB7-2180HS 7.5 HP Two-Stage Air Compressor - 80 Gallon Horizontal, 175 PSI, 22.2 CFM T39 Pump

The ABAC AB7 horizontal series delivers the same 7.5 HP, 22.2 CFM two-stage performance as the AB7 vertical models, on a low-profile 80 gallon horizontal ASME tank that fits under benches, shelving, and low ceilings where a 75-inch vertical unit will not. The belt-driven T39 two-stage pump combines an aluminum block with cast iron cylinders and inner cooling technology for cool, continuous operation at a maximum 175 PSI. Choose 230V single-phase (AB7-2180HS), 230V three-phase (AB7-2380HS), or 460V three-phase (AB7-4380HS).

How it compares

Within the 2-Stage Hybrid Pro range the pump and motor are identical across tank formats, so the choice comes down to footprint and features. The AB7-2180V vertical puts the same 22.2 CFM on a 25 x 34 x 75 in footprint at 403 lbs, which saves floor space but needs ceiling height. The AB7-2180HFF Full Feature horizontal adds a pressure-actuated automatic tank drain and a low oil level switch on the same chassis. If you want a full cast iron pump rather than the aluminum and cast iron hybrid, the Ironman ABC7-2180V delivers 21 CFM from a C1 cast iron pump.

Typical applications

Shops with height restrictions or mezzanines, mobile service buildings, and installations where the compressor tucks under a workbench or against a knee wall. ABAC rates the Hybrid Pro range for air and water spraying, impact wrenching, and driving fasteners, so a single AB7 supports several technicians on impacts, sanders, and spray guns without the recovery lag of a smaller single-stage machine. The 80 gallon receiver keeps the pump from short cycling between tool triggers.

Installation notes

Specify the voltage and phase that matches your panel before ordering: the 230V single-phase version draws the highest current of the three and usually wants a dedicated circuit, while the 230V and 460V three-phase versions suit shops already running three-phase service. In the horizontal format the discharge and tank drain sit low, so leave service clearance on the drain side. Moisture carries over on any 175 PSI reciprocating compressor running hard, so pair the AB7 with an ABAC COOL refrigerated air dryer sized against your actual duty cycle if you are spraying finishes or feeding pneumatic controls.
