SPU300 Auxiliary Power Unit

The SPU300 is a state-of-the-art electric and pneumatic power source designed for long range, high performance business jets.

Best in class power-to-weight ratio

Leading edge control system (FADEC)

Health monitoring capability

Its unequalled power-to-weight ratio is the best in its class. The APU is able to operate unattended on the ground and in-flight. The SPU300's ability to provide power and main engine starting (MES) up to the aircraft's operating ceiling at over 50,000 ft. allows operators to maintain altitude, while other APUs require a drop in altitude of up to 20,000 ft.

The SPU300 is equipped with a leading edge control system, integrated with the aircraft systems so the aircraft can provide live feedback, enabling live troubleshooting and monitoring of key operating characteristics for preventive maintenance.
