Airtabs™ are unique, Vortex Generators (VG) that have been specially designed for trucks. They work by creating a controlled swirl of air, or vortex, which actually reduces wind resistance (or aerodynamic drag). Aerodynamic drag has long been a target for fuel economy on trucks.
Airtabs™ Dramatically reduce the ‘fish tailing’ on trailers and have made tremendous impact on the handing of double trailers in Australia and North America. Here you can see Airtabs™ fitted to the tractor, (these can be painted to match the color of the truck). In this area, the vortex prevents air from entering the gap and creating turbulence.
Airtab has been subjected to on road testing and controlled trials at both Millbrook Proving Grounds and by MIRA. In the USA, Canada and Australia, Airtab has been tested over Millions of road miles. Irrespective of where they are used the benefits remain the same. The results, testimonies and details of the benefits Airtab offer have been obtained from: on vehicle telemetry, fuel flow meters, independent observers, vehicle drivers and fleet operators.
Increased Fuel Economy
Fuel Flow meters and telemetry results recorded by users show that an Airtab equipped vehicle will outperform identical fleet vehicles. Benefits have ranged from an improvement of 1.12% at a minimum to 9.44% as a maximum. Average fuel savings across UK and global testing consistently show long term savings of around 3-5%*. This figure coincides with the findings of the MIRA report.
Users can enhance their “Green Credentials” as a result of fitting Airtab, as any reduction in fuel used has a direct relationship with reductions in carbon emissions. For example a 3% fuel saving means a 3% reduction in carbon produced.
Drivers have historically and consistently reported that an Airtab equipped vehicle offers an improvement in vehicle stability whilst driving in windy conditions. To verify these claims two identical vehicles, one Airtab equipped, were tested on the high speed circuit at Millbrook Proving Grounds in windy conditions during January 2012. Following the test runs a fully independent and experienced driver confirmed that the Airtab equipped vehicle was noticeably more stable and needed less driver effort to maintain a straight course.
Those Are Just A Few Main Benefits, There Are Plenty More
Reduces Front Tire wear
Less Weight on Front Tires
Reduces Steering Effort
Reduced Splash & Spray
Improved Visibility in Rain & Snow
Reduced Cross Wind Effects
Reduced Driver Fatigue
Reduced Dirt Build Up
Improved Truck Image
“Total fuel saving for the duration of 4 month trial : $1800 USD”….”Overall vehicle handling was improved”….” Improvement in fuel economy of 6.06%”….” We are pleased with these results…
Mr. Bill Dinino, Fleet Man
I recently purchased a set of Airtabs for my 1998 century class freightliner. My truck would not handle well in strong winds, until I installed air tabs, now my truck is more stable in strong cross winds or just severe weather conditions. You can really tell the difference thank you air tabs. Thank you

“The drivers are very satisfied with the handling of the trucks after Airtabs™ are installed. We also are seeing a reduction in fuel consumption. The figures are a bit early to say, but the trend is clear.”
Leif Erlandsson, Jale Company
“When I first heard about Airtabs I was skeptical. Then I checked your website and read the testimonials. For a couple hundred dollar investment, and diesel at 3 bucks, I had to try them myself. The installation was as easy as advertised, I did my whole tractor in about 45 minutes. Then I hooked up my trailer and headed down the road. I couldn’t believe the difference! The increase in stability and the lane tracking in gusty conditions is noticeably improved. As for a mileage increase, it’s hard to tell because of the ever-changing loads and routes I take. I can tell the mileage and top-of-the-hill speed is better but it would be tough to document. I would strongly recommend that all trucks use Airtabs. Thanks, Airtabs!”

I installed my order of Air Tabs just before heading back home to Thomasville, GA. At 170 miles, the fuel gauge was only down to 3/4 when usually it would be about 3/8 to 1/2. Thinking there might be a problem, I stopped and filled the tank…..13.35 mpg. I’ve never seen anything over 12.1 and that was only once as I recall. Most generally, the fuel efficiency on the Columbus, GA to Thomasville, GA run is 10.01 to 10.9 MPG. The next week I got 12.25 MPG with about 50 city miles on the tank. Yes, the truck handles differently on the highway. There is less influence from passing big traffic and the tail plume is greatly reduced. So, with the only difference being the installation of the AirTabs, I am realizing an improved fuel economy.
