Freight Wing has released a new side skirt that it claims can improve fuel economy by up to 5 percent.
“This segment of the van market, while not large, has an opportunity to cut its fuel bills and reap a payback in a matter of months with side skirts,” says Sean Graham, president of Freight Wing. “With our side skirts for dry van trailers, payback is often less than 35,000 miles of utilization. It’s only slightly more with side skirts for box fairing trailers.”
Attached to the storage box on each side of the trailer, the fairings are made of automotive grade plastic. A full fairing starts at the beginning of the trailer and connects to the belly box directing airflow around the storage container, Freight Wing says. The belly box profile is then extended downward with the Freight Wing fairing to about 8 in. from the ground.
According Graham, the CARB-compliant box fairings are a first in the industry and are robust and durable. “Weighing in at 80 lbs., the fairings are able to flex and bend, so if the fairing hits a curb, or scrapes the ground, they bounce back and keep their shape. In addition, installation is typically only one to two hours.”
