Airtabs are patented wishbone shaped vortexgenerators designed to reduce aerodynamic drag. Each Airtab ® createstwo controlled swirls of air or vortices that combine to reduce thesuction and drag at the rear of fast moving vehicles. Airtabs work onany square backed vehicle, commercial or private, that spends anappreciable amount of time at highway speeds. These vehicles includesemi tractors and trailers, straight trucks, cube vans, horse trailers,toy and utility trailers, RVs and buses. Airtabs are also effective oncars that have a rear window slope of greater than 30 degrees.
Airtabsimprove vehicle stability by altering the airflow at the vehiclesrear. This has had a dramatic effect on the handling characteristics ofClass 8 rigs in North America and the famous truck trains in Australia.
