Our 3-Bottle Aircraft Oxygen System Service Cart comes complete with a booster and regulator system, and is designed for remote (ramp) and/or in-hangar use. This cart uses N2 to drive the O2 booster, or shop air if used in hangar (100 psi input). The tilting bottle rack allows for easy loading and unloading of bottles. The 5th-wheel steering provides optimal in-hangar maneuverability by hand, while the heavy-duty running gear and towbar allow for unlimited vehicle towing across the ramp or airfield.
