Technical Specs
The Airman SDG25LX takes everything that makes the base model SDG25S great and turns it up a notch. Built in Japan with Airman’s renowned precision and reliability, this 22 kVA diesel generator combines heavy-duty site durability with advanced control and extended runtime.
The Japanese engineering powerhouse perfected the formula for reliable no-nonsense generators back in the late 80’s and they haven’t changed much since then, in the best way possible. It’s why we love them, you’re investing in a generator, that truly is simply the best product on the market.
Powered by the proven Kubota V2403-K3A engine, the LX series features an ultra-long-range 180 L double-bunded fuel tank, providing up to 45 hours of runtime at 75 % load, perfect for remote worksites, rental fleets, and automatic standby systems.
At the heart of the system is the Deep Sea DSE7310 MKII controller, enabling automatic start/stop, comprehensive system protection, and optional remote monitoring via DSE WebNet. This makes it equally at home in a construction yard, agricultural setup, or critical-power standby installation.
Quiet, efficient, and built to last, the SDG25LX is a genuine Japanese workhorse engineered for maximum uptime and minimal fuss.
