Tronair 07-3000-0922 Aircraft Defueler Cart with Totalizer (Gallons)

The Tronair 07-3000-0922 defueler cart provides a safe and efficient way to defuel aircraft, transferring fuel while filtering out contaminants and removing water. It’s ideal for maintenance operations that require cleaning, storage, or transfer of fuel between tanks. The unit’s integrated totalizer allows technicians to accurately track the volume of fuel removed during service.

This defueler is designed for use with a wide range of general aviation, business, and commercial aircraft equipped with compatible fuel fittings. It can safely defuel both piston- and turbine-powered aircraft. Always refer to your aircraft maintenance manual to verify compatibility with the Tronair system before use.

The totalizer measures and displays the exact number of gallons pumped, helping technicians maintain accurate fuel quantity records during servicing. It’s fully resettable and designed for precision, making it easy to verify the amount of fuel recovered or transferred between tanks.

The defueler cart operates using a clean, dry air source regulated to a maximum pressure of 50 PSI (3.45 bar). Excess air pressure can damage the diaphragm pump or affect fuel flow control. A built-in pressure regulator and safety valve protect the system during operation.

The defueler features a 1/2-micron fuel filter with 98% particle removal efficiency, ensuring that fuel is thoroughly cleaned during the defueling process. This protects both the aircraft and storage tanks from contamination by dirt or water. When a noticeable drop in flow occurs, the filter should be replaced to restore proper operation.

Yes. The air-operated diaphragm pump on the Tronair 07-3000-0922 can safely run “dry” without damage. This allows technicians to purge the system of residual fuel after defueling is complete, thereby minimizing fuel loss and reducing the risk of contamination.

Before defueling, connect the static discharge cables from the cart to both the aircraft and the receiving fuel tank ground points. Proper grounding prevents static buildup and potential sparks that could ignite fuel vapors. Never operate the defueler without verifying that all grounding connections are secure and intact.

Fuel flow can be controlled through two main points: the air control valve for primary regulation and the aircraft fueling nozzle for secondary flow control. This dual-control setup provides smooth, adjustable transfer and helps prevent overfilling or fuel spillage during defueling.

Routine maintenance includes inspecting hoses and fittings for leaks, replacing filter elements when restricted, and checking air supply lines for wear. Periodically clean or replace the diaphragm and valve seals using Tronair’s recommended pump diaphragm kit (K-3181) to maintain system integrity. Always use OEM parts to ensure compliance and performance.

Store the defueler in a dry, covered environment to protect hoses, reels, and gauges from moisture and UV exposure. Disconnect the air supply and release any residual fuel from the hoses before storage. For long-term storage, drain the system completely to prevent degradation of the pump diaphragms and seals.

Tronair offers a one-year limited warranty that covers manufacturing and material defects, along with a 90-day warranty on replacement parts. The warranty excludes consumable items, routine maintenance components, and damage caused by misuse, unauthorized modification, or other similar causes. Customers should contact PJi with the unit’s model and serial number for warranty service.
