When open, the airfoil extends about 42 inches behind the trailer and adds a slight curve, which streamlines the airflow and reduces the low pressure pocket behind the vehicle.
When closed, the compact design allows the airfoil to lay flat against each door, over the pipe-locks, and allows the doors to open without any interference for docking.
Simple driver interaction when opening and closing, and the self-closing/self-protecting function, allow the Tailwind to be operator friendly.
Simple design and mechanics allow for a strong and lightweight solution that works.
