Eco Flaps offers aerodynamic solution for tanker trucks

November 1, 2018 (Brentwood, Tenn.) – Eco Flaps is rapidly changing fleet performance throughout the trucking industry with its ecologically-sound splash guards. The company’s mud flaps are one of the most adaptable aerodynamic solutions on the market today and are SmartWay, CARB and GHG2 approved. Eco Flaps recently completed an evaluation with Exa Corporation on the use of its aerodynamic splash guards on tanker trucks to illustrate the product’s significant fuel savings

         “Historically, tankers have had limited options when it comes to aerodynamic devices,” said Bren Marshell, vice president of sales for Eco Flaps. “Our recent testing with Exa Corporation proves that Eco Flaps is a viable option for this segment of the trucking industry.”

         In April 2018, Eco Flaps hired Exa Corporation to perform an aerodynamics and fuel economy analysis through computational fluid dynamics simulations (CFD). The analysis simulated four different configurations in order to understand how the Eco Flaps splash guards performed when installed on a day cab tractor and tanker trailer. The different configurations included: a baseline with conventional mud flaps on the tractor, tanker trailer and fender; Eco Flaps splash guards on the tractor, trailer and fender; Eco Flaps installed on the traitor and trailer, but conventional mud flaps on the fender; and an equipment setup with no flaps used.

         The results showed a 2 percent improvement in drag at highway speeds when Eco Flaps were on the tractor and trailer, but conventional mud flaps remained on the fender. The use of Eco Flaps on the tractor, trailer and fenders indicated a 2.8 percent improvement in drag. The total fuel savings from the full swap out is estimated at 1.4 percent.

         “This analysis from Exa Corporations shows that utilizing Eco Flaps on all sections of the tanker truck provides drivers with the greatest fuel savings,” said Marshell. “At these numbers, drivers can achieve ROI within just three months.”

            In addition to fuel savings and reduced maintenance, the use of Eco Flaps greatly reduce splash and spray from inclement weather and increase safety on the road. Fleets can purchase Eco Flaps from all major truck and trailer manufacturers through Eco Flaps’ distribution network. Eco Flaps are available in multiple sizes ranging from 18” x 24” to 24” x 36” to meet each truck’s dimensions and are backed by a full two-year warranty. They are also available in custom colors with custom graphics. For more information about Eco Flaps, visit
