Section II. EQUIPMENT DESCRIPTION
1.8 CHARACTERISTICS, CAPABILITIES AND FEATURES.
The AAFARS, figure 1-1, is a modular, four man portable, four-point refueling system. AAFARS provides filtered fuel at
fifty-five
gallons per minute to each of the four nozzles 100 feet (30.5 meters) apart. The system will operate satisfactorily
from 120*F (48.9*C) to -25*F (-31.7*C).
The basic components of the AAFARS are the pump-engine module; the liquid fuel filter-separator; the accessory module;
and the hoses, nozzles and fittings that deliver fuel from the fuel drums to the fueling points. The system allows a choice of
three recirculation setups to filter the fuel during operation. Fuel recirculation also prevents pump overheating due to static
pressure build.
All fuel delivery components (hoses, pump, filter, wyes, tees, elbows, nozzles, etc.) feature unisex dry-break couplings, with
the exception of the valved camlock elbow couplings that connect the fuel hoses to the fuel drums. Valved unisex couplings
are dry break fittings. They can be connected or disconnected only when the valves are closed. This allows components to be
separated without spilling fuel. When connected (with valves open) the unisex couplings are locked together, preventing
accidental separation.
The AAFARS is designed to operate normally from four 500-gallon fuel drums. The system includes an adapter kit that
allows the AAFARS to be connected to any source which can be accessed through two-inch, three-inch, or four-inch camlock
couplings. The adapters also allow connection of AAFARS components to any other fuel system components that use
standard two-inch, three-inch, or four-inch camlock couplings.
A twenty-four VDC auxiliary pump is provided to defuel the system after a mission or operation. The auxiliary pump is also
useful for pumping down a component before or after removal from the system due to operational reconfiguration or
maintenance action.
