The Airman SDG25 Series Diesel Driven Portable Generator is powered by a Isuzu 4LE2T Diesel engine and provides exceptional performance with over 32 hours of runtime at full load. Delivering 20 kW / 25 kVA of prime power, this generator features auto start as a standard option. The SDG25 includes automatic voltage regulation (+/- 0.5%) and an exterior potentiometer for precise voltage selection.
Available in a Variable Frequency Drive (VFD) model, the VFD allows the 20kW generator to start a 20 HP pump or motor that would typically require a 50 to 55 kW generator, offering significant efficiency and cost savings. The VFD also provides precise control over motor and pump speeds, ensuring versatility while addressing potential light loading issues.
