AirDog® II-4G Bracket & Spacer
AirDog® II-4G Fuel Air Separation
System featuring Demand Flow Technology and Enhanced Features
AirDog® II-4G is designed to operate at
flows and pressures beyond the maximum requirements of the
engine. It receives fuel under vacuum from the fuel tank containing
entrained air/vapor, particulate contaminates and unknown
quantities of water.
The fuel passes through the water separator
which removes the large particulate contaminates that could
damage or jam the gear rotor fuel pump. The fuel, with only
entrained air/vapor and tiny particulate contaminates remaining
enters the fuel pump.
The fuel, now under positive pressure flow,
enters the fuel filter. As the fuel passes through the filter
media and the remaining particulate contaminates are caught
and contained, the entrained air/vapor is also separated.
Through the positive fuel air separation features of the patented
AirDog® II-4G the separated air/vapor is discharged from
the filter and back to the fuel tank through the Primary Air/Vapor
The fuel passing through the filter media
is now free of contaminates and power robbing air/vapor. At
pressures and flows able to meet the needs of the engine,
it exits the fuel filter through two passageways. First, the
fuel for the engine passes into the fuel pickup tube and on
to the engine. Then, the excess fuel not needed by the engine
recycles internally through the pressure regulator back to
the water separator.
