Technical Specs
The Airman SDG45LX is built for serious work. Designed and manufactured in Japan, this 40 kVA diesel generator combines precision engineering, rugged build quality, and exceptional runtime for demanding applications.
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 a turbocharged Kubota V3600-T-K3A engine and paired with an Airman AVR brushless alternator, the SDG45LX delivers smooth, stable power output for both continuous and standby operation. Its 355 L double-bunded fuel tank provides up to 51 hours of runtime at 75 % load, making it ideal for long duration site power, backup systems, and remote operations.
Equipped with the Deep Sea DSE7310 MKII controller, this model supports auto-start functionality and remote monitoring, offering complete integration for hybrid or standby setups. With a noise level of just 57 dB(A) at 7 m and Airman’s renowned build quality, the SDG45LX sets the benchmark for dependable, quiet, and efficient site power.
