AirDog 2-4G Fuel Air Separation Systems

PureFlow AirDog® II-4G Fuel Preporator

The AirDog II-4G Fuel Air Separation System is a 4th Generation Fuel System for high performance fuel delivery.

The PureFlow AirDog® II-4G lift pump provides superior diesel fuel flow and pressure for optimal engine performance. The AirDog 2 4G fuel pump intakes your diesel fuel with contaminants. The AirDog II 4G Fuel preporator supplies pressurized diesel fuel to a fuel water separator filter. The AirDog II 4G Water Separator Filter separates the large suspended contaminates that could damage or jam the gear rotor fuel pump. Once the Diesel Fuel has had the large particles and water removed it then passes into the Diesel Fuel Filter. These Diesel Fuel Filters on the Lift pump then begins the filtration process using Fourth Generation Diesel Fuel Pump to remove:

  • Entrained Air
  • Vapor
  • Dirt
  • Sediment
  • Debris
  • Emulsified Water
  • Entrained Water

The now purified diesel fuel is then passed through the fuel pump where it is pressurized and sent to your engine's fuel injection system.

The fuel, now under positive pressure flow, enters the fuel filter. As the fuel passes through the filter media and the remaining particulate contaminants 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 Discharge Port.

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.

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 contaminants 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 Discharge Port.

PureFlow 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 contaminants 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 Discharge Port.
