The Atlas Air Force AF9-120H is a 7.5 HP, two-stage air compressor built around a USA-made 120-gallon horizontal steel tank for large automotive shops and industrial operations with sustained air demand. Its two-cylinder, belt-driven pump runs at a low 1,750 RPM and delivers 23 CFM at 90 PSI and 22 CFM at 175 PSI, with a 145–175 PSI working range. The horizontal tank provides a substantial air reserve for demanding applications, while the compressor requires 220V single-phase power, a 40-amp breaker, and #8 wire.
The AF9-120H combines low-RPM operation with commercial controls and features designed to simplify routine maintenance. An Eaton magnetic starter manages electrical input to the motor, while the industrial Hubbell pressure switch controls compressor cycling. The finned tank inlet tube helps cool incoming air and reduce moisture accumulation inside the tank. A hands-free tank drain extension routes condensate to an accessible location, while the compressor oil drain extension tube makes scheduled oil changes easier to perform. The heavy-duty metal belt guard covers the drive components, and included vibro-isolation pads help reduce vibration transferred to the shop floor.
With its 120-gallon storage capacity and 22 CFM output at 175 PSI, the AF9-120H is suited to multi-bay automotive shops, industrial facilities, and other professional operations where compressed air is needed throughout the business day. The horizontal tank layout provides substantial storage without requiring a tall vertical installation, while the two-stage pump is designed for higher-pressure operation. The 3/4" NPT outlet provides the connection point for the shop's compressed-air system.
