Aerox High Pressure Filler Valve / Recharger - MS22035-1 - 5450

The Aerox 5450 is designed to safely and efficiently refill aviation oxygen systems from a high-pressure oxygen source. It acts as a regulated interface between oxygen cylinders and portable or built-in aircraft oxygen systems, ensuring controlled oxygen transfer. The assembly’s robust brass and stainless-steel construction makes it ideal for both FBO and private aircraft servicing operations.

This valve is compatible with most aviation-grade oxygen cylinders and portable oxygen systems that conform to CGA-540 fittings, including Aerox, Avox, and Scott systems. It can also be used with military and corporate aircraft setups that meet MS22035-1 specifications. Users should always confirm connector compatibility and oxygen pressure limits before use.

The filler valve features precision machining and high-quality sealing components, minimizing leakage and preventing contamination during the filling process. Its durable high-pressure design and smooth valve operation allow for safe control of oxygen flow. Aerox also recommends purging lines before and after each use to maintain oxygen purity and system safety.

Routine maintenance involves inspecting seals, threads, and valve operation for wear or leaks. The unit should be kept free from oil, grease, and moisture since these contaminants can react violently with oxygen under pressure. Aerox recommends periodic testing and inspection by an authorized service facility to ensure the valve continues to meet FAA and MIL-spec safety standards.

Installation involves securely attaching the filler valve to the oxygen supply cylinder using a CGA-540 connection, then connecting the output line to the receiving aircraft oxygen system. The recharger’s design allows for smooth hand-tightening and controlled pressurization. Always follow Aerox’s oxygen transfer procedures to avoid rapid pressurization, which can cause overheating or oxygen loss.

Yes. The Aerox 5450 is versatile enough to support both portable oxygen setups and integrated aircraft oxygen systems. It provides a reliable interface for filling portable cylinders used in general aviation or servicing onboard systems at maintenance facilities, making it a valuable tool for both aircraft owners and FBO technicians.

The 5450 filler valve is designed for high-pressure oxygen systems, operating at pressures up to 3,000 PSI (approximately 207 bar), which covers most standard aviation oxygen cylinder ranges. This high-pressure capability ensures complete charging of modern DOT and TC-approved cylinders without compromising accuracy or safety.

Aerox manufactures the 5450 valve from corrosion-resistant brass and stainless steel, both of which are chosen for their strength and compatibility with high-purity oxygen environments. These materials prevent oxidation, leakage, and degradation of performance over time. The precision-machined components ensure durability even under repeated pressurization cycles.

By enabling quick, controlled refills directly from cascade or high-pressure tanks, the Aerox 5450 reduces turnaround time for oxygen servicing. Its reliability minimizes downtime and maintenance interruptions while maintaining oxygen quality standards. For FBOs that service multiple aircraft daily, this translates to smoother operations and improved safety compliance.

The Aerox 5450 conforms to MS22035-1 military specifications and is built under FAA-approved manufacturing standards for aviation oxygen equipment. It meets all applicable guidelines for high-pressure oxygen handling, ensuring safe operation across general, commercial, and military aviation environments. Using Aerox-certified components ensures traceability and compliance with regulations for oxygen servicing activities.
