Tronair 10-6402-0010 Aircraft Lavatory Cart – 31-Gallon Fill, 68-Gallon Dump

Yes. The cart comes standard with the H-1416 flowmeter, which accurately measures the quantity of fluid transferred during servicing. This built-in counter enables ground crews to precisely monitor fill and dump operations, ensuring proper fluid management and compliance with aircraft lavatory servicing procedures.

This aircraft lavatory cart includes a 31-gallon fill tank and a 68-gallon dump tank, both made of durable, non-corroding HD polyethylene with UV protection. These tanks provide sufficient capacity for multiple lavatory servicing operations without frequent refilling or emptying. The materials and construction help maintain water purity while resisting chemical damage.

Waste fluid from the aircraft lavatory is collected through the cart’s dump system, which features a 4” aluminum tank flange and an 18” long, 3” I.D. dump hose for secure connections. The design features a gravity drain valve with a removable fitting, allowing for safe and spill-free emptying into approved disposal systems. This helps maintain clean ramp operations and reduces the risk of contamination.

The fill system uses a hand-operated pump capable of delivering one gallon of fluid for every six strokes. A ball valve allows technicians to control water flow for flushing operations and to drain the hose before disconnecting from the aircraft. This setup provides both precision and safety, ensuring proper pressure and preventing overfilling or leakage during service.

Yes. The 10-6402-0010 features a towbar for manual movement or vehicle towing, along with pneumatic tires and front wheel brakes for stability and control. Its compact frame design allows smooth towing up to 10 mph across ramp surfaces, making it suitable for use around various aircraft parking areas.

Routine maintenance includes lubricating wheel bearings and front swivel plates every six months, as well as inspecting all hose connections for leaks. Tanks and hoses should be washed regularly with mild detergent, following local environmental regulations. Tronair also recommends checking tire pressure (not exceeding 50 PSI) and ensuring that all bolts remain securely fastened.

The cart is constructed primarily from heavy-duty steel weldments and HD polyethylene tanks that resist corrosion and UV degradation. These materials ensure durability and long service life even under constant exposure to weather and chemicals commonly used in aircraft sanitation systems. The powder-coated finish adds additional protection and visual durability on the ramp.

Yes. Tronair offers several optional kits for the 10-6402-0010, including fill and dump connector kits (K-2410 and K-2412), a hose cap kit (K-3606), and a conversion kit (K-4456) that upgrades the cart to an electric fill pump system. These accessories enhance functionality and convenience, depending on the specific needs of your maintenance operation.

The cart uses pneumatic tires with semi-sealed bearings on the front and tapered roller bearings on the rear. The front tires (410/350 x 4) and rear tires (4.80/4.00 x 8) are designed for stable handling and durability, even on rough ramp surfaces. Proper tire inflation and maintenance help maintain smooth operation and minimize wear.

The lavatory cart includes a drain-back system on the fill hose to prevent spillage and a braking mechanism on the front tires to lock the cart in a static position. Additionally, the unit’s low towing speed rating (max. 10 mph) and sturdy frame design enhance safety during ground handling. These built-in features protect both equipment and personnel during aircraft servicing.
