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

The ABAC AB7 vertical series steps the 2-Stage Hybrid Pro platform up to 7.5 HP, pushing 22.2 CFM at a maximum 175 PSI: enough continuous air for multiple technicians running impact tools, sanders and spray guns at once. The belt-driven T39 two-stage pump pairs an aluminum block with cast iron cylinders and inner cooling technology on an 80 gallon vertical ASME tank, so the air reaching the receiver is already cooled rather than carrying the full heat of compression. Choose 230V single-phase (AB7-2180V), 230V three-phase (AB7-2380VS) or 460V three-phase (AB7-4380VS); all three deliver identical airflow and share the same chassis.

How it compares

Every 80 gallon AB7 runs the same T39 pump and the same 22.2 CFM at 175 PSI, so the decision is footprint and fitted equipment, not output. This standard vertical build is the baseline. The AB7-2180VFF Full Feature vertical adds a pressure-actuated automatic tank drain and a low oil level switch, which is worth the step up in a shop where nobody is assigned to the compressor. The AB7-2180HS horizontal puts the same machine on a 25 x 71 x 48 in footprint for shops without 75 inches of ceiling, and the AB7-2180HFF is that horizontal in Full Feature trim. If 22.2 CFM is more than the shop draws, the 5 HP AB5-2180VP delivers 16.6 CFM on the same 80 gallon vertical tank. If you want a fully cast iron pump instead of the aluminum and cast iron hybrid, the Ironman ABC7-2180V gives 21 CFM from a C1 cast iron pump, and where noise is the constraint the AB7-2180VQP Quiet Power holds 22.3 CFM at 69 dBA.

Typical applications

Multi-bay auto repair and body shops, tire stores, welding and fabrication bays, woodworking shops and farm buildings: impact wrenching, grinding, orbital sanding, fastening, and air or water spraying where tools run through most of the shift. A two-stage pump recovers faster than a single-stage machine of the same horsepower, so two or three technicians can stay on tools without waiting on pressure. The 80 gallon receiver keeps the pump from short cycling between tool triggers, and the vertical tank holds that full reserve on a 25 by 34 inch floor footprint.

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 normally wants a dedicated circuit sized to the motor nameplate; the 230V and 460V three-phase versions suit shops already running three-phase service. Plan for 75 inches of clear height plus room above for the discharge line, leave service clearance at the drain and the belt guard, and keep the intake away from paint fumes and sanding dust. Belts, filters and oil are the routine service items on this range, so keep a set on the shelf.

A two-stage pump still pushes warm, wet air into the line, so size a refrigerated dryer above the 22.2 CFM output, such as the ABAC COOL 35, before the air reaches paint, tires or pneumatic controls.
