Atlas® AF14G — 14 HP (Kohler CH440, Electric Start) Air Compressor
A gas-powered compressor is the difference between running full shop air at a job site with no power hookup and having to schedule around whatever electrical access happens to be available that day.
The Atlas® AF14G is a gas-powered 2-stage reciprocating compressor rated for 14 HP (Kohler CH440, Electric Start) with a 30 gallon horizontal tank, built for shops and commercial operations that need compressed air on tap all day without paying for accessories they don’t need.
Who the AF14G Is Built For
- ✅ Construction sites, agricultural operations, and remote job locations where electrical power isn't available and reliability matters most
- ✅ Service trucks and mobile technicians who need dependable air for large impact wrenches and pneumatic tools away from the shop
- ✅ Buyers who prefer Kohler engine architecture over Honda for parts availability, dealer network, or personal brand preference
- ✅ Fleet operations already running Kohler-powered equipment who want to standardize on one engine platform for easier maintenance
- ✅ Field-service techs who need slightly more horsepower headroom than the 13HP AF13G offers for the same tank size and CFM class
- ✅ Operations that need a portable, horizontal-tank compressor that mounts easily on a truck bed or trailer
What the AF14G Is NOT Built For
- ❌ Shop-based operations with standard electrical service already available — an electric AF-series unit (like the AF9) delivers more CFM per dollar when gas portability isn't needed
- ❌ Indoor, enclosed-space use — like any gas engine, the AF14G needs ventilation and should not run in an unventilated shop bay
- ❌ Buyers who specifically want Honda engine architecture — see the AF13G instead
What Makes the AF14G Different
Commercial 2-Stage Pump
The AF14G uses a 2-Cylinder, 2-Stage pump built for daily, all-day duty cycles — not a hobby-grade single-stage unit that struggles under continuous shop use.
CFM & Pressure Output
Delivers 25 CFM @ 90 PSI and holds pressure across a 145–175 PSI range, enough headroom to run impact wrenches, tire equipment, and paint tools without the tank running dry.
Plus Package Upgrades
gas-powered unit, no electrical Plus Package accessories.
Power Requirements
gas-powered, no electrical hookup required.
- Construction/agricultural/remote job sites
- Kohler engine preference
- No electrical hookup available
- Shop-based use with power already available
- Buyers preferring Honda engines — see AF13G
