The aircraft nitrogen servicing cart is designed for mobile nitrogen service. It supplies high-purity dry nitrogen for charging, purging, and leak testing from low to high pressure, including aircraft landing-gear shock struts, door cylinders, hydraulic accumulators, and tires.
Aircraft Nitrogen Servicing Cart

· The four-wheel towable design enables easy movement on aprons, in the field, in hangars, and throughout maintenance areas.
· No electrical power is required; compressed air or nitrogen is used as the drive source.
· Automatic cylinder raising and tilting simplifies cylinder replacement and reduces manual handling.
· Oil-free design with self-lubricating seals prevents medium contamination.
· Automatic boosting with shutdown at the target pressure and overpressure protection.
· Charges aircraft tires with dry nitrogen to reduce combustion risk and stabilize tire pressure.
· Recharges landing-gear shock struts with nitrogen to maintain damping performance.
· Charges hydraulic accumulators to maintain energy storage and pressure stabilization.
· Provides inert-gas purging for fuel tanks, oxygen systems, and similar equipment to reduce combustion and explosion risk.
· Fills emergency-system storage cylinders with high-pressure nitrogen.
· Uses nitrogen in place of oxygen for leak testing of oxygen systems.
