I love my AirDog systems, have them installed in two Volvo truck engines and they’re a night and day difference compared to the factory installed water separator units. Smoother engine, more pulling power at low RPM and a slight but noticeable fuel mileage increase. And to top all that, great customer service from the guys at PureFlow.

My system was installed on August 26th, 2022 and it seems to be doing great! All is well with about 25,000 miles of the system being on the truck! I have noticed a smoother idle and showing a minimal gain in MPGs, but seems to have helped on the low end with horsepower and torque! I have a downsped Volvo D13TC motor, so my RPMs stay really low (850-1100 RPMs), so the help on the low end is a great payoff! Jerry Rone J&A Trucking, LLC
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. Altair7 Transport LLC Roberto Morelli San Miguel, CA
AirDog is an amazing addition to my 2009 Volvo VNL D13. Noticed immediately the throttle response is great! The throttle response is as good as it gets. My fuel mileage hasn't come up much, but hoping that will improve over time. I need to learn how the flow route works on that. The engine idle is smooth and it's noticeably quieter. I'm wanting to buy the heater that goes along with it. I’m extremely happy that I made this purchase of the AirDog and would do it again. Thank you. William Padilla Monticello, IL
I am very happy with the product. I completed the installation myself - it was a very simple install. I have noticed an improvement in throttle response and smoother engine idle. I track fuel and DEF with fuel gauges and DEF mileage did increase. Ian Kirk Sweet Grass, MT & Crossfield, Canada
2016 Volvo DD13 I want to thank you for your product. Engine is smoother, better throttle response, fuel economy increase is about 1/2 mpg, and thanks for helping with install questions. Howie Crawford Trucking Inc. Lancaster, NY
Great install manual. Looking forward to seeing how my old girl does with the AirDog unit. Great customer service! Hansum Haulers Jeff Hansum Canada
The AirDog with the Champ II provides the low-end torque that enabled me to properly re-ratio my rear-ends to leverage the engine's downspeeding capability, giving me almost one mile per gallon fuel efficiency gain. My truck originally came from the factory at 500hp/1650 torque. Now, with the AirDog and Champ II, I have more of each, even with the engine set at 425hp/1550 torque plus re-ratioing the rears to 2.47. More low-end power, increased productivity, more enjoyable to drive, and one mile per gallon fuel savings. The AirDog was the key to putting this truck in its best form ever!

I was pretty skeptical that adding the AirDog to my D11 powered Volvo VNR would increase low RPM pulling power to the degree it has. Adding the AirDog has resulted in fewer downshifts and improved fuel efficiency. Travis Lauer Ploger Transportation
Now after I installed my AirDog, my last 800 mile fill, I got 7.4 mpg. Current fuel mileage is up .4 mpg and shifting much less now with the AirDog installed. When the truck was in a Volvo shop, the shop service manager commented about how smooth the engine sounded. He was quite impressed. Lonnie B. Bartlett, IL
