ABAC AB5-2180V4FF 5 HP Two-Stage Air Compressor - 80 Gallon Vertical Premium, 175 PSI, 14.6 CFM, 230V Single-Phase

The ABAC AB5-2180V4FF is the Full Feature build of the 80 gallon vertical AB5 platform. The two-stage PAT 49 pump pairs an aluminum head and aftercooler with cast iron cylinders, so heat and moisture are pulled out of the air before it reaches the tank, and the FF specification adds a pressure-actuated automatic tank drain and a low oil level switch. It delivers 14.6 CFM at a maximum 175 PSI on 230V single-phase power.

How it compares

The three 80 gallon AB5 models all deliver the same 14.6 CFM at 175 PSI, so the decision is about what comes fitted. The AB5-2180V4NS ships without a magnetic starter, the AB5-2180V4 includes one, and this FF build is specified with the automatic tank drain and the low oil level switch. Where floor space matters more than stored air, the 60 gallon AB5-2160V4 runs the same pump on a smaller footprint.

Typical applications

Body shops, woodworking shops, farm and agricultural buildings, and general maintenance bays: air and water spraying, impact wrenching, screwing, sanding and air tool duty where the compressor is called on through most of the shift. The automatic drain and the oil level switch remove the two maintenance steps most often skipped, which is what earns the step up in a shop with nobody assigned to daily compressor checks.

Two-stage compressors push warm, wet air into the line, so most shops add a refrigerated dryer rated above the compressor's 14.6 CFM output, such as the ABAC COOL 25. Browse the rest of our piston air compressors and our compressed air dryers.
