ABAC AB5-2180VPFF 5 HP Two-Stage Air Compressor - 80 Gallon Vertical Premium, 175 PSI, 16.6 CFM T39 Pump

The ABAC AB5 VPFF series pairs the highest-output 5 HP pump in the 2-Stage Hybrid Pro range with ABAC's Full Feature protection package. The belt-driven T39 two-stage pump moves 16.6 CFM at a maximum 175 PSI, a full two CFM above the standard 5 HP build, and the FF specification adds a pressure-actuated automatic tank drain and a low oil level switch so the two maintenance steps most often skipped happen on their own. All three voltage options ride on the same 80 gallon vertical ASME tank: 230V single-phase (AB5-2180VPFF), 230V three-phase (AB5-2380VPFF), or 460V three-phase (AB5-4380VPFF).

How it compares

Two decisions separate the 80 gallon 5 HP builds, and the first is the pump. The AB5-2180V4FF runs the PAT 49 pump for 14.6 CFM; the VPFF steps up to the T39 for 16.6 CFM on the same tank at the same 175 PSI, which is the margin that keeps a second air tool from pulling the line down. The second decision is the Full Feature package itself. The AB5-2180VP is the same T39 machine without the automatic drain and the low oil level switch, so it suits a shop where somebody checks the compressor daily, and the VPFF suits one where nobody is assigned to it. If the tool list already outruns 16.6 CFM, the 7.5 HP AB7-2180VFF delivers 22.2 CFM on the identical 80 gallon vertical footprint.

Typical applications

Collision centers, dealership service departments, production fabrication shops and busy maintenance bays: impact wrenching, DA sanding, grinding, fastening, and air and water spraying across a full shift. Two-stage compression with cast iron cylinders is built for that duty cycle, and the 80 gallon vertical receiver absorbs the surges so the pump is not restarting every time a trigger is pulled. Where the panel offers it, one of the three-phase builds is the better long term choice, because a three-phase motor draws less current per leg and runs cooler under a hard duty cycle.

A two-stage compressor pushes warm, wet air into the line, so most shops pair one with a refrigerated dryer rated above the compressor's output. The ABAC COOL 25 covers 16.6 CFM with headroom to spare. Part of ABAC's 2-Stage Hybrid Pro range from the Atlas Copco group.
