11–336 kW16 modelsdiesel
Why buyers choose Airman
0.001% warranty claim rate — documented 46,851-hour unit on original components
110% fluid containment standard on ALL units — critical for California environmental compliance
63-68 dB operation with 24-32 hour runtimes — best in class
Oversized generator ends run cooler and last longer than standard-fit competitors
Who Airman is for
Rental fleets buying on total cost of ownership, environmentally sensitive California sites where built-in containment is required, and ultra-high-reliability applications.
What to consider before specifying Airman
*ANA Corp is the sole US distributor — very thin service network
*Japan-sourced parts take 4+ weeks to arrive
*Higher upfront cost — value is in TCO, not purchase price
*Near-zero online user community
