SmartTruck introduced its latest trailer aerodynamic system, which the company said is specially designed for 28-ft. pup trailers and delivers fuel savings of up to 9%.

“Pup trailers present a similar challenge to 53-ft. trailers,” said Mike Henderson, CEO of SmartTruck. “We are applying the same UnderTray design strategies that have worked so well on 53-ft. trailers, using our CFD analysis techniques to understand the different flow field that exists with the pups. We are applying that knowledge to the adaptation of our UnderTray system to provide similar performance for pup operators. The pup UnderTray systems will have the same ruggedness and durability with very quick installations that our customers have come to expect.”

The new system’s components are made in the U.S. of durable polyethylene plastic, a 100% recyclable material. The system includes an aero rain guard for the top rear edge of the trailer, a nose system for the front of the trailer, side fairings and a forward UnderTray for use on straight-frame pup trailers. Different systems are available for both straight frame and drop frame pup trailers.

According to the maker, users can expect the following fuel savings:

Drop-Frame Trailers
Aero Rain Guard and Side Fairings – 2% to 3%
Aero Rain Guard, Side Fairings and Nose System – 4% to 5%

Straight-Frame Trailers
Aero Rain Guard and Side Fairings – 2% to 3%
Aero Rain Guard, Side Fairings and Nose System – 5% to 6%
Aero Rain Guard, Side Fairings, Nose System and Forward UnderTray – 8% to 9%
