Atlas Air Force AF13G Gas-Powered Air Compressor for Mobile Service
Mobile service trucks and remote job sites need real shop-grade air on demand. Battery-powered impacts have their place, but for BUDD wheel nuts, tire-changer duty, and any sustained pneumatic work, you need 145+ PSI and 25+ CFM. Most portable gas compressors top out around 8 CFM — fine for nailers, useless for impact wrenches.
The Atlas Air Force AF13G runs a Honda GX390 13 HP electric-start gas engine on a 2-stage 2-cylinder Atlas pump and a 30-gallon horizontal tank made in the USA. Output is 145–175 PSI and 25 CFM at 90 PSI / 19 CFM at 175 PSI. That's enough air to run 1 in impact wrenches all day from a service truck, not just a nail gun.

Features
-
Honda GX390 13 HP electric-start engine — push-button start, the gold-standard reliability for commercial-grade portable equipment.
-
2-stage, 2-cylinder pump — 145–175 PSI output, runs heavy impacts and tire-changer work.
-
25 CFM @ 90 PSI / 19 CFM @ 175 PSI — covers most professional pneumatic tools sustained.
-
30-gallon horizontal USA-made tank — fits in a service-truck bed, holds enough air for cycle-heavy work.
-
Pneumatic throttle control — engine idles between cycles, saves fuel and reduces noise.
-
Head unloaders — pump starts unloaded, easier on the engine and pump bearings.
-
Vibro-isolation pads — quieter operation, less stress on the tank welds.
-
Finned tank inlet tube — air cools before entering the tank, less water accumulation.
-
Heavy-duty metal belt guard — operator protection, OSHA-compliant.
-
EPA/CARB emission compliant — legal to operate in California and federal job sites.
2-Stage Pumping Is What Makes Real Pneumatic Work Possible
A 1-stage compressor maxes out around 125 PSI and 18 CFM — fine for finish nailers, framing guns, and air ratchets. Real impact wrenches start needing 150+ PSI and 20+ CFM the moment they're under load on a stubborn nut. A 1-stage pump can't keep up — the pressure drops, the tool stalls, and the operator either waits or downsizes to a smaller impact.
The AF13G's 2-stage 2-cylinder pump compresses air twice — first stage to ~80 PSI, second stage to 175 PSI. That delivers usable pressure under sustained tool load. On a service-truck cycle running BUDD wheel nuts, the AF13G delivers full impact torque on every fastener, not just the first few.
Honda GX390 With Electric Start Is the Difference Between a Tool and a Toy
Most portable gas compressors ship with a rope-start clone engine that gets one season of cold-weather service before a sticky carb or fouled plug turns it into a parts donor. The AF13G runs the Honda GX390, the same 13 HP commercial OHV engine used on pressure washers, generators, and ride-on equipment that lives outdoors year-round. Honda's commercial network means parts are stocked at any equipment dealer in North America, not back-ordered from overseas.
Push-button electric start matters when the unit is bolted into a service-truck bed. There's no clearance to swing a recoil rope, and a tech in winter gear can't grip a pull handle through three layers of glove. The 12V starter solves both. The engine is also EPA/CARB emission compliant, so the AF13G is legal on California job sites and federal contracts where uncertified engines aren't.
The Right Compressor for Your Service Truck
The Atlas Air Force AF13G is what real mobile commercial pneumatic work looks like. Honda reliability, 2-stage power, USA-made tank, and the CFM to run impacts all day.
