Dual fuel generators are an ideal power source for small country houses, construction sites, and repair teams. The cost savings when operating a dual-fuel generator are between 50-65% compared to gasoline generators. The multifunction display shows all important operating parameters in real-time, such as voltage, frequency, and the number of operating hours. The GDA 3500DFE features a 12V battery and a built-in starter, allowing the generator to be easily started by turning the ignition key. An improved air filter system protects the engine from overheating, dust, and dirt. The generator is coated with a special corrosion- and chemical-resistant matte finish. Quality control at all stages of production is ensured by a unique serial number.
