By altering the airflow, V-spoilers® gradually reduces the advancement of the trailer, resulting in reduced suction.
The V-Spoiler concept is based on small but powerful Vortex generators, a technology also known from F1 Race and the aeronautical industry.
Each Vortex generator creates two air swirls (vortices) that rotate in opposite directions, and at a speed of approx. 3000 rpm, control the airflow (high/low pressure) and reduce the drag at the rear of your vehicle. It is also useful for “narrowing” the space between the cab and the trailer.
They have been exempted from the maximum width of trailers, due to their aerodynamic and/or reflective characteristics.
