AIRMAN SDG Series Heavy-Duty Engine Generators
Every element of the Airman SDG Series is built to endure the roughest site environments while keeping toxic emissions and acoustics to a bare minimum.
Fully Bunded Oil Fence (Eco-Friendly)
No separate external fuel bund is required! The complete package contains an all-inclusive double-wall steel fuel tank and integrated fluid containment fence with up to 110% total capacity to protect against hazardous leaks.
Weatherproof Ingress Protection
Specially designed air inlet ports increase structural oxygen flow while drastically minimizing suction pressure. Premium automotive-grade insert type seals completely prevent rainwater infiltration.
Seamless Dual Voltage Selection
Easily switch three-phase voltage ranges back and forth from 200/220V to 400(380)/440V via short connecting plate adjustments in the control terminal. Instant indicator lamps confirm voltage live on the fly.
Super Silent Attenuation
Highly attenuated exhaust muffler structures are mounted on precision anti-vibration supports. Tight panel clearances and structured intake sound traps keep acoustics comfortable for urban locations.
Low Transient Reactance Alternator
Coupled with low transient reactance alternators and heavy reinforced damper coils, wave distortion is minimized. This safeguards precision industrial servers, computers, and medical equipment.
Automatic Fuel Air Bleeding
No more tedious manual priming. If the engine stops due to empty fuel, simply top off the tank, turn the starter key to the ON position, and the system automatically bleeds trapped air out of lines instantly.
