AirDog?? II Fuel Air Separation System featuring Demand Flow Technology
AirDog?? II 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 gerotor fuel pump. The fuel, with only entrained air/vapor and tiny particulate contaminates remaining, then 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 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.
How AirDog?? Works
All Diesel Engines Need a 'State of the Art' Fuel Filtration Delivery System!
The solution is Fuel Preporator?? ƒ?? the only filtration delivery system that separates air from the fuel, as well as water and particulates, and maintains the proper pressure flow to the transfer pump, eliminating cavitation and vapor. Fuel Preporator significantly improves diesel engine performance and is approved for sale and use in California by CARB.
Fuel Preporator's effectiveness has been proven over millions of truck miles and verified by EPA & CARB Certified Olsen Ecological Laboratory testing under ISO 8178 8 Mode Test criterion. Discover how patented Fuel Preporator technology can deliver for you:
Increase fuel economy. (Extend fuel filter life)
Increase torque output. (Enjoy a quieter engine)
Improve throttle response. (Enjoy a smoother idle)
Reduce exhaust emissions. (Optimize engine performance)

Engineers Have Long Known About Entrained Air In Diesel Fuel
Cummins?? Engine Co., Service Topic 5-135 states:
"Like water, fuel contains a certain amount of dissolved air depending upon the fuel temperature, pressure on the fuel, specific gravity and the amount of aeration to which the fuel has been subjected."
Caterpillar??, Special Instruction 651-1250 points out:
"Normally No. 2 Diesel Fuel contains about 10% air in solution, although the air is not visible."
Milwaukee School of Engineering, Handbook of Hydraulics agrees:
"Hydraulic oils also contain varying degrees of entrained air."
Parker - Racor Technical Support confirms:
"Fact ##1; There is Air entrained in diesel fuel."
"Damage can be caused by anything in your fuel system that should not be there, including particles, heat, water and air bubbles."
"Air becomes entrained in diesel fuel through agitation from pumping and sloshing in the tank. Additionally, the engine's transfer pump, operating under a vacuum, as with the conventional filter system, has a limited pressure flow available. This limited flow, which is insufficient to fully fill the pump mechanism at higher operating RPM's, results in pump cavitation and vapor. At higher altitudes, atmospheric pressure, the force that drives fuel from the tank, through the lines and filter, and into the transfer pump, decreases. This increases cavitation even more. Conventional fuel filter systems do nothing to relieve these conditions. In fact, as the filter becomes more restrictive to the fuel flow as it plugs with use, these conditions become much worse!"
University of Illinois Department of Mechanical & Industrial Engineering, College of Engineering's study of diesel fuel concludes:
"Diesel fuel is vaporized in a conventional filtering system and is allowed to pass on to the injector system."
"Air is also allowed to pass on to the injector system."
"These phenomena are undesirable because the two-phase flow from the conventional filtering system not only reduces the mass flow rate from the fuel pump but also leads to a lag in injector timing. This lag in the injection of the fuel can have a considerable negative effect on the performance of a diesel engine."
"Unlike the conventional filtering system, the Fuel Preporator?? does not allow vaporized diesel fuel to be created, nor does the Fuel Preporator?? allow entrained air to be passed on to the engine. The Fuel Preporator?? eliminates the inconsistency that is found in a conventional fuel filtering system."
