The Atlas Air Force AF7 is a commercial-grade, two-stage air compressor with a 5 HP single-phase motor, heavy-duty cast-iron three-cylinder pump, and an 80-gallon vertical tank made in the USA. It delivers 18.5 CFM at 145 PSI and 14.5 CFM at 175 PSI, giving shops useful airflow across its working pressure range. The vertical configuration keeps the footprint to approximately 36" × 24", while the included magnetic starter manages electrical input during repeated start-stop cycles. Power requirements are 220V single-phase with a 30-amp breaker and #10 wire.

The three-cylinder pump uses two low-pressure cylinders feeding one high-pressure cylinder, allowing the compressor to reach higher pressure through staged compression rather than forcing the entire workload through a single cylinder. The low-RPM motor works with the cast-iron pump to support the heavy-duty design, while vibro-isolation pads help control vibration and noise during operation. A finned tank inlet tube helps reduce moisture accumulation inside the receiver, and the hands-free drain extension makes routine condensate removal easier without reaching underneath the tank.

The AF7 is built for automotive repair shops, fabrication facilities, and serious home or professional workshops that need substantial compressed-air capacity from a single-phase system. Its 80-gallon vertical tank provides a large air reserve without taking up the floor space of a comparable horizontal compressor, making it practical where available shop space matters. The combination of 18.5 CFM at 145 PSI, two-stage cast-iron construction, and single-phase power makes it suited to demanding pneumatic tools and other applications requiring sustained air supply.
