The Atlas Air Force AF14G is a gas-powered, two-stage air compressor combining a 14 HP Kohler CH440 electric-start engine, a 2-cylinder pump, and a 30-gallon horizontal steel tank made in the USA. It delivers 25 CFM at 90 PSI and 19 CFM at 175 PSI, with a working pressure range of 145–175 PSI. Because it runs on gasoline rather than requiring a 240V electrical connection, it can supply compressed air on service trucks, at jobsites, and in work areas without access to shop power.

A pneumatic throttle control adjusts engine speed in response to air demand, reducing the need to run at full throttle between tool uses. Head unloaders relieve pressure on the engine during restart, helping the electric-start system turn the engine over more easily. The engine’s charging system replenishes the starter battery while the compressor operates. For mobile installations, vibro-isolation pads help dampen vibration when the unit is mounted on a truck bed or trailer. The tank’s finned inlet tube also helps limit condensate buildup during operation, while the 3/4-inch NPT outlet accommodates high-flow air connections.

The AF14G is suited to mobile mechanics, field-service crews, and jobsite operators who need substantial airflow away from a fixed compressor or dedicated electrical supply. Its output can support demanding pneumatic tools, including large impact wrenches used for stubborn lug nuts during roadside or on-site service. The horizontal tank and gas engine make it a practical option for service vehicles and trailers equipped to carry a 30-gallon compressor.
