Easy to maneuver

The low-profile design, mounted on a towable trailer with fifth-wheel steering, makes this ultra-reliable engine-driven 400 Hz GPU easy to maneuver around the congested apron areas of modern airports.

Due to the low weight of the GPU, you can tow it around even with small towing equipment thus reducing the total cost of ownership.

Less fuel, fewer emissions

The low fuel consumption of the Hobart 4400 family results in big savings on your fuel costs as well as reducing harmful engine emissions.

Easy Access

The engine, alternator, controls, batteries and cables are all easily accessible but completely protected under a tough, corrosion-free canopy made of resilient medium-density Polyethylene. All maintenance points that need to be checked regularly (fuel, oil, water, etc.) are easy to access. The entire canopy can be removed by hand in less than two minutes – no hoists or cranes needed.

Power Two Aircraft

with one GPU?? YES

As one of the most advanced GPUs in the market, the 4400 is available in a dual voltage AC/DC version. This combo unit is capable of delivering 400 Hz and regulated 28.5 VDC power, simultaneously and independently! The 28.5 V Active Rectifier Unit (ARU) - available as a standard option - delivers superior voltage quality at the aircraft plug without jeopardising the 400 Hz voltage. It goes without saying that the ITW GSE 4400 will power your aircraft, whether a narrow body or a turbo prop, wherever you need it, whenever you need it!

Operator / Technician Friendly

The clear, icon-based user interface, shown on a high-res color screen is easy to operate and helps ensure correct operation. The display can be customized to suit most language requirements. Technicians can also use the control interface for monitoring operating data, maintenance and practical trouble-shooting.

NB: Display shows optional second 400 Hz outlet and optional 28 VDC outlet.
