​AirDog® - Delivering Pure Fuel To Diesel Engines

March 2017

JEFFERSON CITY, 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 down the highway. The average for entrained air in nearly any diesel engine is about 6-12%. 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? It has a negative effect on fuel mileage. Have you ever noticed that your truck has a very slight “miss” when it is idling? This is one of the effects of entrained air running through the injectors. 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 444 Cummins engine. Charlie noticed that his truck had a rough idle and began studying the problem. He soon realized 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 2016, leaving a lasting legacy that will benefit the diesel engine for many years to come.

Today, PureFlow Technologies is proud to offer the next generation of the Fuel Preparator®, the AirDog® FPII 4G and AirDog® Champ I and II.

The AirDog® FPII features a 4G HD industrial pump and fuel filter/low pressure indicator. It has an electric motor and gerotor fuel pump mounted on a filter base and typically mounts in place of the trucks water separator. The AirDog® FPII 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 systems. It uses the high pressure of modern fuel pumps to remove water, air and particulants and is warranted for 4 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.

The AirDog® Champ I & II are both designed to use the truck’s high pressure fuel system to push the fuel through the separator, eliminating the need for a separate motor pump and wiring. All AirDog® products not only remove entrained air from the diesel fuel, but also remove water and solid particulants. AirDog filters feature a 6-micron microglass filter with a service life of around 35,000 miles and beyond in some cases.

The AirDog® Champ II uses a CAT filter and will not void CAT Platinum Warranties on the engine and injectors. All AirDog® products are protected by worldwide patents as well as manufacturer warranties. Both the AirDog® Champ I and Champ II have become popular with owner-operators and fleets for their ease of installation and short return on investment, usually under 4 months. Most customers experience a fuel economy gain of .3 to .5 mpg or more.

New for 2017 from Pure Flow Technologies is a universal sandwich mounting bracket that works on most applications to effectively eliminate the need to drill the frame when mounting AirDog® products.

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 diesel engine run better and increase horsepower.
