FlowBelow has announced a new quick-release fairing option for the company’s Tractor AeroKit system, allowing fleets to quickly remove fairings for easier access.
The quick-release mounting system allows drivers to remove the fairings in seconds without tools to accomplish tasks such as installing tire chains in quick order. The new feature is designed for fleets that have been resistant to using drive wheel fairings on trucks for accessibility reasons.
The Tractor AeroKit maximizes the aerodynamic performance of the company’s wheel covers by also controlling the airflow between the wheels and behind the wheels. Based on SAE fuel economy testing, the fairings have demonstrated a significant fuel savings of 2.23% in combination with wheel covers, which is over three times the fuel savings of wheel covers alone.
“With the exception of the Freightliner Cascadia with Aero package, which comes standard with our wheel covers, over 80% of our customers utilize the complete AeroKit as opposed to wheel covers alone,” said Josh Butler, FlowBelow CEO. “Most fleets cannot even measure the fuel savings of wheel covers by themselves. By enhancing our AeroKit with quick-release fairings we are targeting customers that desperately want achieve the maximum fuel savings possible without creating extra work for their mechanics and drivers.”
