The above video is an example of how the airflow moves beside and behind a trailer.
Flimed at night in the rain.
Note clear lane to the left of the truck amd how the spray is laid down behind the trailer.
Night Rain Again
The video above shows how an AirWedge alters airflow around a trailer.
Note how much spray passing trucks make.
Our test truck is pulling two 48' trailers, each with an AirWedge installed.
The video above shows under-trailer airflow using smoke. Of interest is how the smoke moves forward in the same direction as the trailer without our Winglets installed.
