Wabash National’s AeroFin XL Tail Device is an aerodynamic solution designed to improve trailer aerodynamics and overall fuel economy.
The AeroFin XL directs airflow across the rear of the trailer to reduce aerodynamic drag on the vehicle. The device deploys and retracts automatically with swing-door operation without assistance from the driver and does not interfere with trailer loading and unloading.
The device features a more compact and lighter weight design when compared to more conventional aerodynamic devices, according to Wabash.
When used with Wabash National’s Ventix DRS drag reduction system the AeroFin XL provides more than a 10% improvement in fuel economy – a claim that was certified by an independent third-party in accordance with SAE J1252 Wind Tunnel Test, according to Wabash.
Together, the Ventix DRS and AeroFin XL are verified as an EPA SmartWay Elite aerodynamic device combination. The SmartWay Elite designation is a new category for the SmartWay Technology Program that recognizes devices providing the highest levels of fuel savings.
When used alone, Wabash said that the AeroFin XL provides more than a 4% improvement in fuel economy.
“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,” said Brian Bauman, vice president and general manager at Wabash Composites.
The AeroFin XL and other aerodynamic trailer solutions will be featured at the 2016 TMC show.
