The Emco Wheaton G457 Helicopter Refueling Nozzle was originally developed for military applications. This nozzle is designed to ensure that fuel cannot be accidentally delivered into the engine air intake during hot refueling. Commercial Helicopter operators will appreciate the significant cost advantages in terms of the reduction in turbine cold starts occurring from the ability to safely refuel with rotors turning.
The G457 Helicopter Fueling Nozzle may also be used for "Open Line" refueling of all types of aircraft. The nozzle is designed for a maximum inlet pressure of 110 psi (7.6 bar) and flow rates from 10 to 70 GPM (38 to 265 LPM).
