Jet Ex 6D – Hobart Ground Power Unit – 28.5V DC, 2,000 amp

JetEx 6D by Hobart offers the best combination of user friendly design, superior performance, and proven reliability to provide the best value to our customers.

Jet Ex 6D

The new JetEx®6D operates at 1800 RPM giving a much quieter and more fuel efficient power delivery system. The low profile design, combined with our rugged 5th wheel steering, provides superior visibility and maneuverability in today’s congested ramp areas. The reduced fuel consumption rate provides fuel cost savings and reduces engine emissions, which support the “Going Green” initiatives of the GSE industry.

The Hobart JetEx 6D features the Cummins “QSB” series electronic diesel engine and the Hobart designed and manufactured generator. Integrating customer influenced design, innovative technology, and Hobart’s years of engineering expertise maximizes the GPU performance and maintains the traditional Hobart standard of durability and reliability.

Hobart Ground Power is the name you can trust to meet your aircraft’s needs for reliable 28.5 VDC power.
