Tronair 10-6401-0010 Aircraft Lavatory Cart with Manual Fill Pump

The Tronair 10-6401-0010 lavatory service unit provides a clean, sanitary method for servicing aircraft lavatory systems and for transporting waste fluid to an approved disposal station. It supports both fresh-flush solution delivery and waste removal in a single mobile unit. This dual-system design improves efficiency during routine aircraft ground servicing operations.

This aircraft lavatory cart features a 68-gallon fresh (fill) tank and a 136-gallon waste (dump) tank. The larger waste tank capacity helps accommodate multiple servicing cycles before disposal is required. Both tanks are constructed from non-corroding HD polyethylene for durability and long service life.

Both the fill and dump tanks are made from high-density polyethylene (HDPE) with a UV inhibitor. This corrosion-resistant material helps withstand harsh ramp environments and exposure to chemicals and sunlight. Durable tank construction supports long-term reliability in aircraft ground support operations.

The manual fill pump delivers approximately one gallon of fluid per six strokes. It operates at a maximum pressure of 20 PSI, helping prevent overpressurization of the aircraft lavatory system. This controlled pumping rate supports accurate fluid transfer and safe servicing procedures.

The unit is equipped with a manual diaphragm dump pump rated at approximately 30 gallons per minute. This pump efficiently evacuates lavatory waste into an approved disposal system. A manual diaphragm design reduces reliance on powered systems while maintaining dependable performance.

Yes. The unit includes a drain-back system on the fill hose to help reduce fluid spillage after servicing. After filling, positioning the ball valve correctly allows the hose to partially drain before disconnecting. This design supports cleaner operations and reduces ramp contamination.

The cart is equipped with pneumatic tires and a steering front axle assembly with tapered roller bearings. This configuration supports smooth movement across ramp surfaces and improved control during positioning. The maximum recommended towing speed is 10 mph to help ensure safe transport on the airfield.

Wheel bearings and caster swivel plate bearings should be lubricated with multi-purpose grease at least every six months. Operators should also periodically inspect hose connections for leaks and wash tanks and hoses in accordance with local procedures. Routine preventive maintenance helps extend service life and ensure sanitary operation.

Yes. The manual lists replacement kits for both the fill pump (K-1730) and discharge pump (K-4290), along with additional kits for drain valves, connectors, and tank components. Using OEM replacement parts helps maintain proper performance and preserve warranty coverage. Always reference the model and serial number when ordering parts.

Yes. The Tronair 10-6401-0010 aircraft lavatory cart with manual fill pump includes a built-in flowmeter (H-1416). This integrated fluid quantity counter helps ground crews accurately monitor the amount of lavatory fluid dispensed during servicing. Accurate measurement supports efficient aircraft lavatory maintenance and reduces the risk of overfilling or fluid waste.
