OUR VALUED CUSTOMER FROM ACROSS THE NATION

I ordered filters today and it was amazing customer service. I will most definitely be ordering more in the future. Thank you so much.

Thomas Hershberger

I installed the system on my 8.3 Cummins as soon as I got it [November 2020] – had an order to transport 174 car loads of BMWs, so I needed to hit the road. My truck has performed flawlessly, easier cold starting. Runs great and contrary to earlier assumption is definitely getting better fuel mileage. My 4th qtr IFTA return will tell the tale. Should have bought an AirDog years ago! Thanks

The team drivers left for California from Oklahoma City with a prior average fuel mileage of 6.8. After returning from CA, the new average was 7.8 – a new all-time high for this rig! We are also monitoring the DPF Regeneration and will have additional factual data in lowering the amount of cycles needed.

Before AirDog, there was constant reoccurring engine codes, fuel de-rating and low power. After the installation of the AirDog, none of these problems have reoccurred. The engine regained the power it was designed to have and picked up .2 to .3 mpg. Plus, it has completely eliminated any air locking during filter changes and has over 35,000 miles on the fuel filter.

Great service and support. Purchased the AirDog and Champ II systems for our 2017 Volvo VNL 780 semi truck. Products were excellently packaged, well documented and everything needed to do the job correctly. First time ever that a company followed up on the purchase and installation! Installation kit for a Volvo VNL D13 engine was perfect and correct.

The AirDog works fantastically. Of all the things I’ve added over the years to my trucks, the AirDog has been the largest improvement in performance and potential to increase economy. The very first improvement I’d make with a Volvo/Mack motor.

Finally had a chance to use the motorhome this weekend with the pump installed and WOW! What a difference. I really did see better throttle response and better pulling power! I was able to maintain cruise control speed on slight grades where I couldn’t before.

I put 2 AirDog units on our Krone 1000 with 2 MBE 4000 Mercedes 500hp engines. The AirDogs have made a big difference. We are saving 4 gallons per hour and the power is steady and smooth. The engine starts a lot nicer and runs smoother. These units have been trouble free and work awesome.

Understanding the Problem of Fuel Contamination

Fuel contamination is one of the most common and underestimated challenges facing vehicle owners, fleet managers, and mechanics today.
