Aerofficient designed its Slider side fairing for on-highway trailers to expand or contract automatically when the trailer’s axles are moved, filling the gap between the trailing edge of a standard fixed trailer side fairing and the trailer’s tires. The side fairing, which has been verified by the U.S. Environmental Protection Agency’s SmartWay Transport Partnership, is affixed to the trailer’s sliding axles and moves forward and rearward with the axles; no driver involvement is required. If maintenance is required beneath the trailer, the Slider can be detached from the axles and slid forward for quick access under the trailer.
The durable side fairing is made with an engineered automotive-grade injection-molded plastic panel material. The hinged technology is designed to permit the fairings to bend in or out 90 degrees to pass over obstructions without being damaged, hold their shape in extreme temperatures and resist ice and snow packing. A clamp system is designed for fast installation without the need to drill holes in the trailer. The side fairing can be installed with the company’s fixed fairings on new trailers or added to units with existing Aerofficient fixed-side fairings.
