AirDog® - Delivering Pure Fuel To Diesel Engines
JEFFERSON, MO… If you were to take a mason jar and fill it half way with diesel fuel, cap it and shake it for a little while, you would easily see the entrained air created by the movement. This is the same effect that diesel fuel experiences in a truck’s fuel tank while going doing the highway. Add in the cavitation created by the fuel pump, hotter temperatures and increased vacuum that comes with operating in higher altitudes and it becomes apparent that every diesel engine burns fuel that is mixed with entrained air.
So what is the big deal about air in the diesel fuel? Ever notice that your truck has a very slight “miss” when it is idling? This is the entrained air running through the injectors and being burned in the piston. Your truck will still run, just not at an optimum level. The air vapor running through the injectors will cause metal-on-metal wear as the injector is lubricated by the diesel fuel. It will also cause a poor spray pattern, resulting in inefficient combustion and last, but not least, it will wear out the injector’s plunger, causing premature failure. The entrained air is hard on the fuel pump, which is also lubricated by the fuel. Symptoms of the engine include: rough idle, reduced horsepower and torque, less throttle response, harder starts and increased emissions.
Most drivers shrug it off as the way things are – or many are not even aware of the problem. In the 1980s a man named Charlie Ekstam decided to go trucking and bought a truck with a Cummins 444 engine. Charlie noticed that his truck had a rough idle and began studying the problem. He soon discovered that his engine was not running as efficiently as it could due to air trapped in the fuel. A self-taught machinist, Charlie began developing a product in 1990 to remove the entrained air from the diesel fuel and in 1993 introduced “The Fuel Preparator®”. A few years later the product was patented and trademarked as the “AirDog®”. Charlie kept improving the AirDog® until his untimely death in February 2014, leaving a legacy to benefit the diesel engine for many years to come.
Today, PureFlow Technologies is proud to offer the next generation of the Fuel Preparator®, the AirDogII® and AirDog Champ® I and II.
The AirDogII® features a 4G HD industrial pump and fuel filter monitor. It has an electric motor and fuel pump mounted on a filter base and mounts in place of the trucks water separator. The AirDogII® removes water, solid particles and all entrained air from the fuel. Models are available for most diesel engines and it comes with a 5-year warranty.
The AirDog Champ I® mounts to the frame or firewall on the pressure side of the fuel pump. It is made for today’s high-pressure fuel rails. It uses the high pressure of modern fuel pumps to remove water, air and particulants and is warranted for 10 years.
The AirDog Champ II® fits popular Class 8 truck engines, including CAT and Detroit Series 60 with a spin on adaptor that attaches to the existing fuel filter housing, making a very quick and easy installation. It also removes water, air and particulants and comes with a 10-year warranty.
AirDog® models are also available for pick-up trucks through PureFlow AirDog at 877-421-3187 and feature a limited lifetime warranty.
All AirDog® products are made right here in the USA and have applications for nearly all diesel engines. From Class 8 trucks, pick-ups, off-road heavy equipment to marine and agriculture, AirDog will help your engine run better and increase horsepower.
Here are some testimonials from AirDog® customers:

ISX + Signature 600 - Since I have installed the AirDog® FPII-200 my engine is running smoother, pulling better, and I have had a .5mpg increase in fuel economy. I am a true believer in the AirDog® and even had an old Fuel Preporator®. I love the new design and performance it makes a huge difference. I have ordered 3 units and all have done great for me! - David Wesley, Onaga, KS
CAT - I love the AirDog® Champ II it does everything and more that I was promised out of the product. I have about a .5 MG increase, my fuel pressure has leveled off and I am seeing my engine running smoother and pulling better too. - Scott Penn, Fort Peirce, FL
550 ISX - The AirDog® FPII-200 for ISX + signature 600 is great I experience engine running smoother, pulling better, and have a .7 to 1 increase in MPG. I used to have an old Fuel Preporator starting out and I love the new 4G. I have no regrets and love that it is much smaller than the old Fuel Preporator® as well. - Manny Medeiros/ Medeiros Trucking, Hollister, CA
N14 - I installed the AirDog® FPII-200 on my Cummins N14, so far I have experienced engine running smoother, pulling better, and over a 1 mpg increase in fuel! It is everything I was promised and plan on buying more units at this year’s Mid-America Truck Show! - John Casey, Ashland, OH
CAT C15 - I tell all my friends about the AirDog® Champ II! Since I have had it I have experienced engine running smoother, pulling better, and a .5mpg difference in fuel economy. I can really tell a smoothness in the throttle as well! - Darrell Spencer, Georgetown, KY
