ABAC ABC7-2180VFF 7.5 HP Two-Stage Ironman Air Compressor - 80 Gallon Vertical Full Feature, 175 PSI, 21 CFM C1 Cast Iron Pump

The ABAC ABC7 Full Feature pairs the Ironman all cast iron two-stage pump with ABAC's FF protection package, so the machine looks after itself between shifts. A 7.5 HP motor drives the C1 cast iron pump to 21 CFM at a maximum 175 PSI on an 80 gallon vertical ASME tank. Choose 230V single-phase (ABC7-2180VFF), 230V three-phase (ABC7-2380VFF), 460V three-phase (ABC7-4380VFF), or 575V three-phase (ABC7-5380VFF).

What the Full Feature package adds

Three things, and all three are jobs a busy shop forgets or cannot do by hand at all. The automatic tank drain clears condensate on its own, so nobody has to remember the petcock at closing time and the bottom of the receiver does not quietly rust through. The low oil level automatic shutoff stops the motor before the pump runs dry, which is the failure that turns a pump rebuild into a pump replacement. The belt guard aftercooler is the one no habit can replace: it drops the discharge temperature before the air reaches the tank, so a large share of the moisture condenses in the receiver where the drain can get rid of it, rather than travelling down the pipe to your tools. If your crew is reliable about the first two chores and the air does not need to be dry, the standard ABC7-2180V is the same 21 CFM machine without the FF package.

What 21 CFM actually runs

Size on CFM, not on horsepower. Twenty one CFM at 175 PSI covers impact wrenches, air ratchets, hammers, blow guns, grinders and a spray gun, and holds pressure when a second tool joins in for a while. Below it, the ABC5 Full Feature at 16 CFM suits a one or two bay shop running tools one at a time. On this same 7.5 HP vertical platform the ABC7-2180V2FF steps up to the larger C2 pump for 24 CFM, which is the move if a continuous duty tool such as a dual action sander will run most of the day. For two operators on air at once, start instead at the 10 HP ABC10 Full Feature at 32 CFM on a 120 gallon receiver. Sustained work such as sandblasting belongs on a rotary screw, which is rated for 100 percent duty.

Typical applications

Auto repair and body shops, tire stores, woodworking shops, metal shops and light fabrication running air tools through the full workday: equipment operation, grinding, hammering, tire inflation, fastening, orbital sanding and spraying. The Full Feature build suits shops that would rather not rely on someone remembering to drain the tank or check the oil.

Power and air treatment

Take three-phase power if the panel has it, since a three-phase motor starts easier and runs cooler on a compressor that cycles all day, and the 460V build keeps the wire size down on a long run. On single-phase, give it a dedicated circuit sized to the motor nameplate and keep the wire run short. The belt guard aftercooler does real work on moisture, but it is not a dryer: if the air reaches paint, plasma, or pneumatic controls, add a refrigerated dryer rated above this compressor's 21 CFM output. The ABAC COOL 35 leaves headroom on a hot day. Browse all refrigerated air dryers.

Part of ABAC's Ironman cast iron range from the Atlas Copco group. The vertical 80 gallon footprint keeps floor space free while holding enough stored air to smooth out demand spikes, and the all cast iron two-stage pump is the part of this machine that decides how many years it lasts.
