Way Better Fuel Mileage
2005 Cat C15
I heard about your product through Tony Justice. After installing the AirDog, the engine idles smoother, acceleration is better, and fuel mileage is way better. I absolutely love the shipping and friendly service.
Peter Falk
Smooth As Butter
I’ve had the AirDog on since November and am extremely happy with it. Much better idle now, smooth as butter and starts better too. Throttle responds instantly and less black smoke when accelerating. Fuel mileage is hanging in at 6.5 mpg, which is good since it’s winter – normally it drops a half mpg, so I am hopeful I will see an increase this summer.
Definitely would buy another AirDog after running this one, even though it’s been a short time. First time I started the truck, I heard a change in the exhaust tone and knew this was going to be good.
Thanks for a great product and support.

Ecstatic About The Results
2005 Cat C15
Approximately 5 minutes after installation, I noticed a major difference with the engine and how smooth it now runs. The engine has never operated this good since I’ve owned the truck. I also shift less, indicating increased torque. The first full tank was .6-.7 mpg gain, the second tank was .9 mpg gain, and the 3rd tank was .2-.3 mpg gain. The first two tanks were consistent driving conditions and the third tank was at higher cruising speeds. I am ecstatic with the results and cannot stop telling everyone how great the product is. I was initially skeptical, but now am a believer and think the next few tanks will be +1 mpg gain.

Fuel Mileage Increase
AirDog was installed myself on 379 Peterbilt with Cat C15 engine. I have seen about .5 mpg increase in fuel mileage on the road.

Works Flawlessly
2002 Itasca Horizon RV with Cat 3126B Engine
All is great with the fuel system. I have not heard of many people installing the AirDog system on the diesel pusher RV units. However, I think it works flawlessly. I have not put an enormous amount of miles on my unit after installation, but a few thousands of miles I have. So far so good. I also installed a programmer for the Cat 3126B engine…. which is conjunction with the AirDog system has given me more power and ease of mind. I like the combination a lot.

30,000 Miles Out of a Fuel Filter
Cat 3406E
Idle quality is much smoother, plus the engine makes much more power from idle all the way to red line. The mileage has gone up .6 to .7 as an average and I see 30,000 miles out of a fuel filter. Love this product!

Everyone Needs To Know About This Product
1999 Cat 3406E
We have been taking my Cat to the dealer for years on a running issue and that entire time no one could fix it. Immediately after (the AirDog) installation, the motor idled better and was more responsive. The very first run I gained .8 mpg and the power gained was amazing. Plus the problem I put up with for years was cured! Everyone needs to know about this product.

Thank You AirDog
After some time of use, we noticed a loud growling sound that we thought was coming from the (AirDog) unit. We were advised to bypass the AirDog, then send it in for warranty. Immediately after removing it, we found out it was not the AirDog, but our factory Cat transfer pump that quit. Thank you AirDog for getting me home.

Done Wonders for Power and Fuel Economy
I pull big heavy loads, up to 120,000 pounds, with my Cat C15 Acert. Before AirDog, I was getting 2.3 MPG. With my new AirDog, I’m getting 5.5 MPG loaded heavy and 6.5+ MPG on (80,000 lb) light load. I drive easy, but AirDog has still done wonders for power and fuel economy for my Cat.

I’m Satisfied
Purchased Champ II in June 2020 and installed myself on 2002 T-800 Kenworth with Cat C15 engine. Have noticed better throttle response, especially once the fuel got lower in the tanks – it remains constant. After 6 months, I have seen 2/10 of a gallon increase or roughly 4% increase in fuel mileage. I also noticed quite an improvement in power. I’ve told a few of my friends about it and since I took so long to see just how much it changed, they tend to believe me. I’m satisfied.

I’m Impressed
2002 KW 6NZ Cat
Last month (July 2020), I got an increase of about 18% but that can be due to tailwinds, light loads, or a multitude of things, but since I keep good track of my mileage and like to average it over a six month period or so, I’ll let you know in December just how much it has changed. So far, I’m impressed.

Many Benefits Gained
1986 359 Pete with 1994 3406C Mechanical Cat
I usually drive about 125,000 miles annually and use about 29,761 gallons of fuel. After the AirDog was installed, my fuel use dropped to 24,038 gallons! My mpg pulling my Bull Rack before putting the AirDog on was 4.1-4.3, now I get 5.2 and have seen up to 5.7 with no wind and 70-75,000 lbs. Plus, my manifold pressure went from 27 to 33 psi and my exhaust temps dropped from 825 down to 650. The truck puts out less smoke and idles much smoother.

Makes Pulling A Heavy Load Feel Like A Light Load
2006 Kenworth Tractor with Cat C13
With the AirDog installed, the results in fuel savings are 10.70%. The driver stated the truck is quieter, starts easier, runs smoother and has more power. His quote, “it makes pulling a heavy load feel like a light load.”

Pays For Itself
Right after installing the AirDog on my 2005 Cat C15, I noticed the power difference compared to before, plus there was a gain of 0.5 mpg on my heavy loads and a full 1.0 mpg with lighter ones. My wife and I are really pleased with the AirDog as we waited a few months before buying it, but wished we would have bought it sooner. It just makes sense as it pays for itself in just a few months.

Performance and Ease Is Very Impressive
2007 Cat C15
After installing the AirDog on my C15, the last 7,022 mile trip was an average of 6.02 and I have seen 7.34 on a 3,601 mile run. Sometimes I think I should stop and pull the hood to see if it is really a Cat Bridge Engine in my KW! The performance and ease is very impressive when pulling the hills.

On My Trucks Since Early 1990s
I have had fuel preporators on my trucks since the early 1990’s. My 2003 C15 Cat went from 5.4 mpg to 6.2 mpg and with the 4G pump, it is holding at 6.5 mpg. Plus, I have over 50,000 miles on the AirDog microglass fuel filter and is still going.

You Gotta Own An AirDog
I put my first fuel preporator on my 1997 E Model Cat. It worked great, increased fuel mileage and great power. I got a new AirDog 4G system for my 2003 Cat C16. Love all the new features. Can’t believe 30,000 miles on a filter and a C16 getting 6.5+ mpg. You gotta own an AirDog to experience it.

Power and Longevity
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.

Tech Support
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!

Solved Injector Issues
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.

Pull Oversized Loads With Ease
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.

Very Pleased with the Quality
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.

About 0.5 MPG Increase
Installed on 4 Kenworth Trucks
We do all of our own installations at our shop in Kimbolton, Ohio. In terms of throttle response and engine idle, we have noticed better pick up and better pulls on the hills. We track fuel mileage and have had about 0.5 mpg increase. We have also noticed longer time period between filter changes and better start up in cold weather.

Quality Second to None
Installed an AirDog on my 2006 Single Turbocharged ACERT this week. -10° to 30° above zero had absolutely no effect on my typically finicky engine. Unbelievable improvement in all around performance. While I fully suggest keeping up on all bypasses and filters in a stock system for peak performance, this system is a no brainer for reliability and consistent performance from your Caterpillar engine. I’m beyond impressed with performance and also the ease of installation. Quality second to none!

“Really Woke The Dead”

The Results Are Amazing
Newmar 2004 Dutch Star with Cummins ISL 400 Engine
I installed the AirDog on my Cummins powered motorhome myself. Easy installation in the same location as the OEM single fuel filter. Return fuel line from the AirDog was tapped into the original return fuel line. Again, it was an easy job. The results are amazing. Throttle response was noticeable on first test drive. I no longer get the hesitation in acceleration and hiccups while increasing the demand on the engine. Also better mileage – pre-AirDog was about 6.6 and after AirDog is 7.0+. The engine now performs like a 400hp engine should perform. My only regret is not doing the change over much earlier.

Less Downshift, Less Smoke, More Power, & Improved Mileage
2007 Cummins ISX
Right after it was installed, there was an immediate change in the engine performance – less downshifting, less smoke and overall more power. I had to relearn how to drive it with the extra power and my first tank went from 6.87 to 7.41. Even if there was no mileage gain, I had no plans on returning this before the 90 days just for the performance that was gained. Lunch for the AirDog team is on me!

Should Have Bought an AirDog Years Ago!
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

Every Stock System Needs This Upgrade!
Monaco Windsor RV with 8.3L Cummins CAPS
I installed the AirDog myself with the help from the AirDog staff on the phone! The AirDog system has fixed my problem which was downrating my engine. My RV definitely runs much better. My RV is powerful again! My SilverLeaf system is already showing a 2 mpg increase with only a couple hundred miles. I replaced my stock lift pump 3 years ago. I wish I had known more about the CAPS fuel system. I would have put the AirDog pump in at that time. Every stock system needs this upgrade!

GREAT Product
We completed our trip about a month ago after traveling around 5k miles in our motorhome (2003 Rambler Cummins ISC 8.3). After having your product installed, we immediately recognized a smoother, better starting, more powerful motorhome. Additionally, probably the most important to me, was the comfort knowing that I would always have a positive fuel supply feeding the main injector pump! Since the stock design injector pump draws or sucks the fuel from the tank, which is about 30 ft away, the AirDog pump removes this design flaw by providing fuel under pressure, which is a great thing! Another benefit is picking up about 2 additional lbs of turbo boost, which is always a plus. Overall, a GREAT product that I would highly recommend! Thanks again.
P.S. Lance and his team are KEEPERS!

Performed Flawlessly
My Coach is a 2001 Holiday Rambler Endeavor with the ISC engine, the Cummins 8.3 liter. This is similar to several Monaco models of that time period. Our first significant travel since installation of the AirDog system was in November and December 2021. From NC to Northern VA at Thanksgiving and then NC to Southern Florida and back in early January. Probably 3,000 miles on the system.
First, the coach performed flawlessly the entire trip. Of course we did a few miles test run before hitting the road to check for issues like any leaks, etc. Your kit is excellent and instructions are straight forward. When I did have questions, Lance was always quick to get back to me. The technical aspects of the installation were not difficult, but getting to some of the connections was, due to the tight quarters (trying to get two 1″ open end wrenches on JIC fittings where you could barely get one hand into). My installation was probably ideal as the AirDog went directly where the previous primary fuel filter was and I was able to use the existing fuel lines. They were Parker hydraulic hoses and are in good shape in spite of the coach being 20 years old.
Improvements are smoother idling, better acceleration, and although I need more data on fuel consumption to make a firm claim, we got 10 mpg on the return trip from Florida towing our Jeep. Never have we seen above 9.

Many Improvements on a Motorhome
I installed the AirDog system myself on a motorhome with 2000 American Eagle 8.3 Cummins engine. I have noticed a smoother engine idle, improvement in fuel mileage, reduced engine start time, downshift further up on hills than before, and top the hill at higher speeds. I have a tendency to stop at the same fuel stops when repeating our trips from the previous year. I have completed two different trips, both in excess of 1,200 miles. At each stop, I noticed that it was taking fewer gallons to fill. When I returned home, I compared my receipts to the previous year and confirmed this to be correct. Also, crank time when starting the engine has reduced, so it takes less time for the engine to start. Another improvement is hill climbing – on long grades, I have noticed I get further up before the automatic transmission is downshifting to a lower gear and I top the hill at higher speeds. I think it is also important to note that I would not have purchased this system had it not been for the information and assistance provided by your tech support.

Makes a Huge Difference Starting in All Conditions
The AirDog system makes a huge difference in starting the truck [1991 BMY Harsco M925A2 with 8.3L Turbocharged Cummins]. It starts up instantly above freezing and still starts down to 20 degrees without the engine block heater or ether, which was not the case previously. I installed the AirDog myself and have noticed an improvement in throttle response and smoother engine idle. In general, I think the former military vehicle owner community could really benefit from your 24V product! I recommend the system to everyone I encounter with starting/fuel line issues. It makes a huge difference starting in all conditions.

Couldn’t Imagine the Actual Gains I Received
The last three years of operating my 2010 Cummins ISX 550 HP with a competitor’s product, my average economy was 7.2. I was hoping to have some fuel increase from switching to the AirDog, but couldn’t imagine the actual gains I was going to receive. My fuel economy with the AirDog has jumped to 8.5-9.1, plus the filter monitor is a great addition to this product to now know exactly when to change my fuel filter and service the water separator. Way to go, AirDog!

AirDog Is the Way To Go
I have been in the trucking industry for over 20 years and currently operate a 1993 KW with Cummins N14. My runs are coast to coast in Canada at 118,000 lbs and the 48 states loaded at 80,000 lbs with an average mpg of 5.5. (With the AirDog), it now is 6.0 mpg and gained 25 hp. The engine runs smoother and great acceleration! If you enjoy top performance or think you’ve forgotten what performance was, then AirDog is the way to go!

I have tracked a .2-.5 MPG increase, along with smoother idle throughout RPM range and improved throttle response. My engine used to crank for several seconds to fire up, but now it starts instantly. I also used to lose prime on injectors, but now it’s not an issue with the AirDog. Thanks for a great product.

First Choice For Better Performance
Well, who said you can’t teach an old dog new tricks? I have 21 year old Swede with over 2 million miles on a 500 hp Detroit. My truck never ran better! The increased fuel pressure gives me a better throttle response. Engine vibration is minimalized because of less restriction in the delivery system. The fuel is filtered down to 6 microns, which means a better spray pattern for the injectors. If you’re going to keep your truck, then this is the first choice in making your engine perform better. My return on smiles is back!

Customer Gains
We installed the AirDog on our customer’s 500 Detroit 60 series. We previously installed a K&N filter, BullyDog heavy duty gauge tuner and a BullyDog exhaust manifold, which brought the customer’s fuel mileage from 5.4 up to 6.2 mpg and overall HP up to 550 and 1811 torque. Once making a run on our dyno, we quickly realized how much was gained by installing the AirDog. HP went to 569 and torque jumped to a staggering 1888. The customer then left out on his first run of 3,000 miles just to return and report even more gains regarding the fuel mileage. It now sits at 6.7 mpg, so overall gains after the installation were 19 hp, 77 torque and .5 mpg increase.

Roared With Lots Of Power
With the new summer blends at the pump, I hooked a 44,000 lb load. Usually my truck will dog a bit. This time it roared with lots of power on demand – I had the ECM turned back to save on fuel. I can’t wait to share it with my friends. Thanks again.

Regained Power, Increased MPG, & Eliminated Air
2013 Paccar MX
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.

Improved Throttle, Smoother Idle, & Increased Fuel Mileage
2020 Peterbilt with Paccar
I first heard about the AirDog line of products on the XM Radio Road Dog Trucking show and purchased an AirDog in February 2021.

I Love My AirDog Systems
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.

Great Payoff
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!

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.

Amazing Addition
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.

Very Happy
I am very happy with the product. I completed the installation myself on 2016 Volvo 780 D13 engine – 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.

Best Form Ever
2011 Volvo VNL with D13
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!

Fewer Downshifts & Improved Fuel Efficiency
2020 Volvo VNR
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.

Shop Service Manager Was Quite Impressed
Now after I installed my AirDog on my Volvo VED12, 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.

I am using a Universal 150 GPH (PN A3SPBT461-LP) with E7 Mack. Throttle response is a lot smoother, idles better, and fuel mileage is up ½ mpg.

Install Was As Easy As Possible
Got the unit installed on 2016 Mack CHU613 MP8. Smoother idle, throttle response, and peace of mind of 2 more filters. I did have to order some fittings, hose, etc. as I couldn’t fit the unit on the frame, but found an excellent spot and the install was as easy as possible. You make a quality product and I have recommended it to a few friends.

Performing Well Beyond Expectations
2017 Mack CXU613
AirDog was installed on August 19, 2020. So far it’s performing well beyond my expectations. Here are two fuel ups that have been done since the install of the AirDog – 7.19-8.5 mpg pre AirDog and 10.07-10.75 mpg after AirDog installed.

Very First Improvement I’d Make
2020 Mack Anthem with MP7 (11L) Engine
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.

Could Tell A HUGE Difference
2018 Mack MP8HE
This system was installed in the middle of a cross country run out to Oregon. I hardly made it out of the drive and could tell a HUGE difference in low end throttle response after installation. It pulls much better down low especially. I literally had to learn to back off the throttle a bit when taking off. My hats off to the guys and gals at AirDog for making this happen. They’re a joy to work with and have checked back with us to make sure all has gone well with this system. I can’t recommend this AirDog strongly enough! It makes me wonder why manufacturers aren’t installing these air/water removal systems right at the factory. Anyone at Mack listening?

Next Level Performance
2020 Mack Anthem with MP7 (11L) Engine
The AirDog really helps my dog howl! With my overly aggressive downsped engine, the added fuel pressure has it holding gears longer and taking its performance and economy to the next level. #NextLevelTrucking

New Weapon In My MPG Arsenal
2020 Mack Anthem with MP8HE (13L) Engine
Honestly, I did not believe that adding the AirDog to my super downsped MACK Anthem would have any noticeable impact… I couldn’t have been more wrong. Improved low RPM performance, increased high RPM boost psi, and increased fuel efficiency… definitely a new weapon in my MPG arsenal.

Would Not Recommend Another Brand
Highly recommend AirDog. Great (insurance) for your fuel systems. Great service and people to work with when you need it. Always have my filters shipped quickly. Would not recommend another brand other than AirDog itself!!

Very Helpful
Lance is very helpful. Product was shipped the same day. Also included a filter with the AirDog. Great product.

Nothing But Great Things To Say
I have nothing but great things to say about them. They were very easy to get in touch with and had me set up with all my questions answered in no time.

WOW!
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.

Can’t Stop Grinning
Our utility truck was at best making it through the workday; we were looking for something to help with low power. After the installation of the AirDog, we found an enormous gain in power and I can’t stop grinning every time I drive it. You may not need this kind of power to get from one job to the next when cutting grass, but you do need it when delivering heavy loads over hilly streets and highways to customers. AirDog gives you the power to get there on schedule and reduce fuel costs at the same time!

Noticeable Acceleration Difference
2011 Mercedes Sprinter Van V6 Common Rail
There is a noticeable difference on acceleration and especially when driving on the open road. Highway driving was getting 19 mpg. Now with the AirDog, it’s getting 23 mpg.

Works Flawlessly
2002 Itasca Horizon RV with Cat 3126B Engine
All is great with the fuel system. I have not heard of many people installing the AirDog system on the diesel pusher RV units. However, I think it works flawlessly. I have not put an enormous amount of miles on my unit after installation, but a few thousands of miles I have. So far so good. I also installed a programmer for the Cat 3126B engine…. which is conjunction with the AirDog system has given me more power and ease of mind. I like the combination a lot.

Quality Product and Knowledgeable Staff
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.

Trouble Free & Work Awesome
Krone Big X 1000+ Chopper
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.

Night and Day Different
We got the system installed on the yarder. It has been pulling logs steadily for a while now. The response to the engine is night and day different. Here at Offroad Wrench, we plan to continue using your system for our customers.

Makes Pulling A Heavy Load Feel Like A Light Load
2006 Kenworth Tractor with Cat C13
With the AirDog installed, the results in fuel savings are 10.70%. The driver stated the truck is quieter, starts easier, runs smoother and has more power. His quote, “it makes pulling a heavy load feel like a light load.”

Makes a Huge Difference Starting in All Conditions
The AirDog system makes a huge difference in starting the truck [1991 BMY Harsco M925A2 with 8.3L Turbocharged Cummins]. It starts up instantly above freezing and still starts down to 20 degrees without the engine block heater or ether, which was not the case previously. I installed the AirDog myself and have noticed an improvement in throttle response and smoother engine idle. In general, I think the former military vehicle owner community could really benefit from your 24V product! I recommend the system to everyone I encounter with starting/fuel line issues. It makes a huge difference starting in all conditions.

Strongly Recommend to Anyone with an Excavator
The AirDog system is actually on a 2005 Link Belt 210LX excavator. It has really made a difference in the way it performs! Starts better, runs better, has more power through the whole range of operation! I would strongly recommend this system to anyone with an excavator. Fuel delivery is a very common problem with these as the tank is located far from and below the fuel pump. As excavators age, they tend to have problems with rust and sediment in the tank further exacerbating the problem. I believe you should market a system like the one we used to heavy equipment owners.
