The Atlas Air Force AF9G is a gas-powered 9 HP two-stage air compressor designed for mobile service trucks and field mechanics who need compressed air without dependable electrical power. Its Honda GX270 electric-start engine drives a three-cylinder, two-stage pump connected to a 30-gallon USA-made horizontal steel tank. The compressor operates at 145–175 PSI and delivers 18 CFM at 90 PSI and 14.5 CFM at 175 PSI, providing the output needed for demanding pneumatic work, including large impact wrenches used on BUDD wheel lug nuts. The Honda engine is EPA/CARB compliant for operation in California and other CARB-regulated states.

The AF9G combines several features specifically suited to mobile operation. Pneumatic throttle control and head unloaders help manage compressor loading and provide unloaded starts as air demand changes. An integrated charging system helps keep the service-truck battery maintained while the compressor runs. The finned tank-inlet tube helps reduce moisture accumulation inside the tank, while the heavy-duty metal belt guard covers the belt-drive components. Included vibration-isolation pads help stabilize the unit on truck beds and uneven surfaces, and the 3/4" NPT outlet provides the connection point for the air system.

The AF9G is suited to mobile mechanics, roadside service operators, field-service technicians, and truck-based maintenance crews that need substantial compressed-air capacity away from a permanent shop. Its gas-powered configuration eliminates the need for shore power, while the 30-gallon tank provides stored air for demanding tools. The combination of electric starting, battery charging, and load-management controls makes it well suited to service vehicles where the compressor needs to function as part of a self-contained mobile setup.
