Bell 412: Aircraft Oxygen & Nitrogen Servicing Equipment

Aircraft oxygen servicing equipment is used to refill and maintain onboard oxygen systems for both crew and passengers. This includes supplying oxygen to masks, emergency oxygen bottles, and medical oxygen systems, ensuring they are fully operational before each flight. Proper oxygen servicing is essential for meeting regulatory requirements and maintaining safety in case of cabin depressurization or other in-flight emergencies.

Aircraft nitrogen servicing equipment is designed to fill and maintain nitrogen-based systems on aircraft, including tires, landing gear struts, and accumulators. Nitrogen helps maintain consistent pressure, reduces the risk of oxidation, and performs reliably under extreme temperatures. This equipment ensures optimal performance, extending component life and improving safety during ground operations and flight.

Nitrogen is used instead of regular compressed air in aircraft tires and struts because it is inert, dry, and stable under temperature and pressure fluctuations. This reduces the risk of oxidation, corrosion, and moisture-related damage within the system. Using nitrogen also minimizes pressure loss over time, ensuring consistent performance and reducing the need for frequent servicing.

PJi offers a complete range of oxygen servicing tools, including oxygen bottle carts, regulators, and boosters. These products are available in multiple configurations – such as 2-bottle, 3-bottle, and 4-bottle carts – to meet different aircraft and maintenance facility requirements. Each option is built for durability and ease of use, ensuring efficient oxygen replenishment for various aviation applications.

Our nitrogen servicing selection includes nitrogen carts, nitrogen boosters, nitrogen regulators, tire and strut service tools, and tire inflation/deflation tools. These solutions are available in multiple cart configurations and sizes to accommodate both small general aviation aircraft and large commercial fleets. Each tool is designed for reliability, ease of handling, and safe operation.

The right cart size depends on your maintenance volume, aircraft type, and facility requirements. Smaller 2-bottle carts are ideal for light-duty operations or tight spaces, while 3-bottle and 4-bottle carts provide extended servicing capacity for larger fleets or high-demand environments. Our specialists can recommend the best option based on your usage patterns and operational needs.

Yes, many oxygen and nitrogen carts are portable and designed for use in both hangar and ramp environments, including remote locations. Their wheeled designs and durable construction make them easy to move and operate in various ground conditions. This flexibility ensures essential servicing capabilities wherever your aircraft are located.

Servicing intervals depend on aircraft usage, environmental conditions, and manufacturer recommendations. Regular checks before scheduled flights, after extended downtime, or following system repairs help ensure safety and performance. Using high-quality servicing equipment allows for consistent, accurate refills that meet operational and regulatory standards.
