Airtabs™ are unique, Vortex Generators (VG) that have been specially designed for commerical trucks. They work by creating a controlled swirl of air, or vortex which actually reduces wind resistance (or aerodynamic drag) in vehicles. Aerodynamic drag has long been a target for fuel economy.
Airtabs Dramatically reduce the 'fish tailing' on trailers and have made tremendous impact on the handing of double trailers in Australia and North America.
Improves airflow, reduces under car boundry burble, curbs turbulance underneath the vehicle and where the air departs. |
