The Atlas Air Force AF9P is a 7.5 HP, two-stage air compressor with an 80-gallon vertical steel tank, built for automotive shops that rely on compressed air throughout the workday. Its three-cylinder, belt-driven pump runs at a low 1,740 RPM and delivers 23 CFM at 90 PSI and 20 CFM at 175 PSI, with a 145–175 PSI working range. The USA-made tank uses a vertical design measuring 40" × 24" × 71", making it practical when floor space is limited and the compressor needs to fit into a corner of the shop.
Atlas includes the Plus Package to address three common concerns in a frequently used compressor. An automatic low-oil monitor shuts the unit down if oil levels become too low, helping protect the pump from oil starvation. The automatic tank drain removes accumulated condensation on a schedule rather than relying on manual draining, while the air-cooled aftercooler lowers compressed-air temperature before it reaches the tank, helping reduce moisture carried into the air system. The AF9P also includes an Eaton magnetic starter and industrial Hubbell pressure switch, along with a finned tank inlet tube designed to reduce water accumulation inside the tank.
With its 23 CFM output and 80-gallon air reserve, the AF9P is suited to multi-bay automotive shops running lifts, tire equipment, and air tools, as well as smaller professional shops preparing for higher air demand. Vibro-isolation pads help reduce transmitted vibration, while the heavy-duty metal belt guard encloses the drive components. Drain extension tubes also make routine oil and tank service more accessible.

FAQ
What electrical service does the AF9P require?
The AF9P requires 220V single-phase power, a dedicated 40A breaker and #8 wire. The magnetic starter is included, so no separate starter is required. Have a qualified electrician confirm the circuit requirements for your installation.
Is the AF9P quiet enough for a working bay?
Atlas describes the AF9P as extremely quiet for its class. Its 1,740 RPM motor and two-stage pump use a lower-speed design than many higher-RPM compressors. The included vibration-isolation pads also help reduce vibration transmitted to the floor. Normal shop-level operating noise should still be expected.
What does the Plus Package do?
The Plus Package includes three features:
-
Automatic low-oil monitor: Shuts the pump down if oil levels become too low.
-
Automatic tank drain: Removes accumulated condensate without relying on manual draining.
-
Air-cooled aftercooler: Cools compressed air before it reaches the tank, helping reduce moisture in the downstream air system.
Why choose two-stage compression?
The AF9P uses two-stage compression and operates up to 175 PSI. Air is compressed in two stages rather than one, making this configuration suited to shop applications requiring higher pressure and sustained air demand.
Is the tank really made in the USA?
Yes. Atlas specifies the 80-gallon vertical steel tank as made in the USA. The pump, motor and electrical components are sourced separately and assembled into the complete unit.
