Aero WC270-RJ3E


Designed for Major and Regional airlines and busy FBOs, the WC270-RJ3E is the “Large” in AERO’s Small-Medium-Large “RJ-Series” water carts. Like the RJ and RJ2 Series, the RJ3 Series carts are built to exceed commercial airlines’ rigorous standards for ramp equipment durability. The RJ-Series carts set the standard for quality in aircraft ground support equipment.


As stand-alone units bolted into a trailer, the electric-powered WC270-RJ3E is the industry’s only convertible” potable water cart: it can be inserted into a 3/4-ton pickup truck to change the carts from towable to drivable. The 46-inch (116.8cm) deck height (made of grip-strut and diamond-plate steel) is low enough for servicing regional jets but provides plenty of height for servicing larger jets.


The WC270-RJ3E Electric Potable Water Service Cart utilizes AERO’s popular stand-alone WC270-Insert tank system. The FDA-approved 270-gallon (1,022 liter) water tank includes an immersion heater to keep the water from freezing. The pump and fill hose sit in the insulated and heated, split-lid rear compartment.



The WC270-RJ3E – like all of AERO Specialties’ lav and water carts – comes complete with all required hoses, couplers, and fittings.
