ABAC AB5-2180V4 5 HP Two-Stage Air Compressor - 80 Gallon Vertical, 175 PSI, 14.6 CFM, 230V with Magnetic Starter

The ABAC AB5-2180V4 is the 80 gallon vertical AB5 built with motor protection fitted from the factory. A heavy-duty 184T frame motor and a magnetic starter shield the motor and the pressure switch from the over-amping damage that comes of starting hard and often, which matters in a shop where the compressor cycles all day rather than once an hour. The two-stage PAT 49 pump, aluminum with cast iron cylinders, delivers 14.6 CFM at a maximum 175 PSI on 230V single-phase power.

How it compares

The three 80 gallon AB5 V4 builds run the same pump and deliver the same 14.6 CFM at 175 PSI, so the choice is about what comes fitted. The AB5-2180V4NS is the bare build and ships without a magnetic starter, which suits a shop that already has starter and disconnect gear on the wall. This AB5-2180V4 includes the starter. The AB5-2180V4FF Full Feature build adds a pressure-actuated automatic tank drain and a low oil level switch. Where floor space matters more than stored air, the 60 gallon AB5-2160V4 runs the same pump at 301 lbs in a 22 x 27 x 69 in footprint. For more air on the same 80 gallon tank, the AB5-2180VP steps up to the T39 pump and 16.6 CFM.

Typical applications

ABAC lists this two-stage belt drive range for automotive, industrial, agriculture and farm, and food and beverage work. In practice that means body and repair shops running impact wrenches, DA sanders and grinders, production woodworking, metal fabrication, and farm buildings where the compressor is called on through most of the shift. The magnetic starter earns its place anywhere the unit starts and stops dozens of times a day, since it is the repeated inrush current that takes out an unprotected motor and pressure switch first.

A two-stage compressor pushes warm, wet air down the line, so most shops pair one with a refrigerated dryer rated above the compressor's 14.6 CFM output, such as the ABAC COOL 25.
