The GPU-406 Ground Power Unit features a compact design with a full-size performance which allows for easier handling and better mobility near aircraft. It features a brushless, high-efficiency generator running at an optimized 2000 RPM providing improved fuel efficiency and reduced sound level while ensuring rapid transient response and exceptional frequency regulation. Powder-coated aluminum and fiberglass panels surrounding a rugged galvanized steel chassis provide the longest-lasting finish. Mobility is enhanced by a rubber torsion axle, tight radius 5th wheel steering, simple direct-acting brakes, and a safe no-drop towbar. The GPU meets U.S. and EURO latest emissions standards. Other engines are available for all emissions-regulated locations.
