US trailer builder Wabash National has added a fifth product to its trailer aerodynamic solutions range, the AeroFin XL Tail Device.
According to Wabash, the AeroFin XL is a lightweight and durable tail device that directs airflow across the rear of the trailer to reduce aerodynamic drag, reportedly providing over four per cent improvement in fuel economy when used as a stand-alone device.
When used in conjunction with Wabash’s Ventix DRS (drag reduction system), the AeroFin XL is meant to provide over 10 per cent improvement in fuel economy, as certified by an independent third party in accordance with SAE J1252 Wind Tunnel Test, the company said.
Together, Wabash said the devices are verified as an EPA SmartWay Elite aerodynamic device combination, a new category for the SmartWay Technology program that recognises devices providing the highest levels of fuel savings.
“We have a responsibility to our customers to continually provide innovative solutions that lower their total cost of ownership,” said Brian Bauman, Vice President And General Manager, Wabash Composites.
“After extensive research, development and testing, we’re pleased to offer the AeroFin XL as another option to help fleets reduce their fuel consumption, operating costs and greenhouse gas emissions.”
According to Wabash, the device deploys and retracts automatically with swing door operation, requiring no additional interaction from the driver and does not interfere with trailer loading and unloading.
