2003 Cat C15 After running another product and not seeing any improvement, I found out about the AirDog. I could not believe the difference and how advanced the product was. Power and longevity of the engine was more important to me than the .3 mpg increase, but the fuel savings is great. Aaron B. Texarkana, TX

1997 Cat 3406E When pulling the hills in Missouri, I had always thought this Pete could beat anyone to the top, but after the AirDog, there is no doubt it will be the first! Shane H. Owensville, MO

Cat C15 I purchased the AirDog in hopes to increase my fuel mileage; with little to no increase at first and became skeptical right away. After speaking with their tech support, we worked back through the installation to find the issues and now I have gained performance and a 0.5 mpg that the truck never had! James G. Erie, PA

The City of Huntington Beach Fire Department has installed six AirDog units onto our Pierce Arrow XT engines with Cat C13 power plants. We were having problems with fuel injectors failing due the amount of heat and significant fuel aeration in the fuel delivery system. Much of the problem was determined to be caused due to the distance between the fuel tank and the transfer pump. We reached out to PureFlow Technologies to see if they had a transfer pump that could be incorporated into the existing system near the fuel tank. They advised me about their AirDog system designed for our exact problem. Since we have installed the AirDog systems, we have had no signs of injector seal issues and no injector failures. In addition to having a quality product, the staff at PureFlow Technologies have been very supportive and are very knowledgeable about today’s fuel delivery systems and their inherent problems with aeration. Thanks to PureFlow Technologies and the AirDog, we feel that we have taken a step in the right direction to solve what has been an industry wide problem that is costing fleets a lot of money and making OEMs null about the issues.

Cat C15 with Regen My truck performs like never before since installing the AirDog system. Now I have plenty of power and I am able to pull my oversized loads during regen cycle with ease. The AirDog system does exactly what they told me it would! My truck and typical load is 50 meter blade grossing just under 95,000 lbs. Alex D. Chapin, SC

I installed the AirDog and right away the engine [Cat C15] was smoother. My fuel mileage went from 5 to 5.8 mpg. I run the same route every day, so there aren’t any other factors that would have affected the fuel mileage. I am very pleased with the quality of the AirDog system. Best of all, it’s made in the USA. Jason H. Wooster, OH
