PureFlow AirDog® manufactures and supplies AirDog® Fuel Air Separation Systems and high performance lift pumps for diesel pick-up trucks. AirDog® works by using the Fuel Preporator®. The system can improve diesel engine performance by separating the entrained air from the fuel, also improving fuel economy through improved injection timing, increased power and better fuel burn. The effectiveness has been proved over millions of miles and verified by the EPA and CARB Certified Olsen Ecological Laboratory testing under ISO 8178 8 Mode Test criterion. An engine equipped with the Fuel Preporator® has consistently shown a timely injection and will perform at peak power output and efficiency regardless of the fuel filter condition.
