AeroFlex fairings boost trailer efficiency

AeroFlex fairings, which have demonstrated up to a 7.5% improved fuel economy for tractor-trailer rigs, are available from Carrier Transicold's North American dealer network. Carrier Transicold is a part of Carrier Corp, a business unit of United Technologies Corp.

Developed by Freight Wing Inc, AeroFlex trailer side fairings offer a boost to fuel economy, based on independent tests verified against the SAE/TMC J1321 Type II test procedure, according to the manufacturer. A verified EPA SmartWay technology, fairings are now required on many trailers operated in California.

Available for standard as well as refrigerated trailers, patent-pending AeroFlex fairings are made of impact-resistant, flexible TPO (thermoplastic olefin) plastic that maintains a good appearance over the long haul. The material is UV-stabilized for prolonged outdoor use. Flexibility of the material, coupled with a 180-degree top hinge, allows the low-clearance fairings to flex and withstand both side and bottom impacts. AeroFlex fairings have a three-year limited warranty, backed by Carrier's coast-to-coast dealer network.

Weighing 160 pounds, AeroFlex fairings can be installed in a 5-degree angled configuration. This “wedge” configuration more efficiently diverts airflow along the side of the trailer, away from drag-inducing rear wheels, axle components and crossmembers. Designed for ease of installation, the fairings can easily be modified to accommodate under-trailer fuel tanks in refrigerated trailer installations.

In 2007, Carrier Transicold became the first nationwide distributor of Freight Wing's original aluminum “gap” and side fairings, products the company continues to offer.
