Aerofficient has developed an innovative sliding trailer fairing

Aerofficient developed a new innovative system designed for trailers which expands or contracts the slider fairing depending on the trailer’s axle position. The company says that thanks to this feature the fuel efficiency is improved with up to 80 percent compared to the fixed trailer fairings. With the new system the gap between the trailing edge of the fairing and the front tire is completely eliminated thus minimizing the drag coefficient.

Jim Reiman, CEO of Aerofficient declared: “In TMC Type IV testing by a prominent fleet using an independent fuel economy testing expert, our Slider fairing boosted fuel savings by 80% over trailers using standard fixed fairings in a zero wind condition when the trailer’s tandems were set at the 41-ft. setting. Assuming 60,000 miles of highway driving and $4.00 per gallon fuel cost, the Aerofficient Slider will save $1,235 more than a standard side fairing.”

“The greater the gap between the trailing edge of the fairing and the trailer’s front tire, the less efficient the side fairing becomes,” said Marty Fletcher, executive director of product development and fuel economy testing expert with Aerofficient.

The Aerofficient Slider is affixed to the trailer’s sliding axles and moves with the automatically axles, without any need for driver involvement. The new system will start to be produced in April.
