7.5HP 80-Gallon 2-Stage Vertical Air Compressor
A multi-bay auto shop running impact guns, tire changers, and lifts on the same air system burns through CFM faster than a single-stage 5HP compressor can deliver. As soon as two bays pull air at once, pressure crashes and tools slow down. The fix is a 2-stage commercial compressor with enough storage and CFM to keep multiple bays running without pressure drops.
The Atlas Air Force AF9 is a 7.5HP 2-stage commercial air compressor with an 80-gallon USA-made vertical tank and a 3-cylinder pump that delivers 23 CFM at 90 PSI and 20 CFM at 175 PSI. A magnetic starter controls electrical input to extend motor life, and the 145-175 PSI pressure setting keeps a multi-bay shop above tool minimums.

- Restoration shops and serious home garages
Features
-
7.5HP commercial 2-stage pump — 3-cylinder, 2-stage pump delivers commercial-shop output without the CFM crash of a single-stage compressor
-
80-gallon USA-made vertical tank — large reservoir means longer time between motor cycles and steady pressure during peak air-tool demand
-
23 CFM at 90 PSI / 20 CFM at 175 PSI — keeps multiple bays running impact guns, tire changers, and lifts without pressure drop
-
145-175 PSI pressure setting — higher pressure ceiling than a typical 125 PSI compressor — feeds tools that need more pressure
-
Magnetic starter included — Eaton magnetic starter controls electrical input and extends motor life vs a direct-pressure-switch start
-
Industrial Hubbell pressure switch — commercial-grade pressure switch built for daily duty cycles
-
Hands-free tank drain extension — extension to the tank drain valve lets the operator clear condensate without crawling under the tank
-
Finned tank inlet tube — reduces water accumulation in the tank by cooling the air before it enters
2-Stage 3-Cylinder Pump and CFM Output
Single-stage compressors compress air from atmospheric pressure to working pressure in one cylinder pass. That's fine for a small home garage but it limits maximum pressure and reduces motor life under continuous duty. The AF9's 2-stage 3-cylinder pump compresses air in two passes — first to a lower intermediate pressure, then to final working pressure — which lets the compressor reach 175 PSI without overheating the cylinders.
CFM output measured at the working pressures tells you what the compressor can actually do: 23 CFM at 90 PSI for typical air tools and 20 CFM at 175 PSI for high-pressure applications. That's enough for multiple bays running impact guns and tire changers simultaneously without the pressure crash that turns a 5HP single-stage into a bottleneck.
80-Gallon USA-Made Tank with Magnetic Starter
The 80-gallon vertical tank is USA-made and built from steel — verified domestic manufacturing rather than imported tank assembly. The vertical orientation saves floor space in a working shop, and the finned tank inlet tube cools incoming compressed air before it hits the tank, reducing water accumulation that would otherwise need to be drained frequently.
The Eaton magnetic starter controls electrical input to the motor, so the pressure switch only triggers the starter — not the full motor load — which extends the motor's life considerably compared to direct-pressure-switch operation. The Hubbell industrial pressure switch is built for daily commercial duty cycles, the heavy-duty metal belt guard protects the drive belts, and a hands-free tank drain extension lets the operator clear condensate from a standing position.
The Right Commercial Air Compressor for Your Shop
At 7.5HP with a 2-stage 3-cylinder pump, 80-gallon USA-made tank, and 23 CFM at 90 PSI output, the AF9 sits in the sweet spot for commercial auto, body, and tire shops. The 145-175 PSI pressure ceiling and 80 gallons of storage keep multiple bays running simultaneously without pressure crashes.
Magnetic starter, industrial pressure switch, vibro-isolation pads, hands-free tank drain extension, compressor oil drain extension, finned tank inlet tube, and heavy-duty metal belt guard all ship with the unit. Overall dimensions of 40" L x 24" W x 71" H fit a working shop layout, and 220V single-phase operation on a 40 amp breaker with #8 wire keeps the electrical install standard.
