Airtab is a patented wishbone shaped vortex generator designed to reduce aerodynamic drag at two key vehicle locations; the tractor-trailer gap and the rear of any square backed vehicle or trailer that routinely attains highway speeds. Airtab works on commercial transportation vehicles as well as on cube vans, SUVs, RVs, buses, a variety of trailers, bobtail tractors, flat bed, grain or cattle haulers and tankers.Each Airtab creates two tight swirls of air that combine to reduce suction and drag at the rear of a vehicle traveling over 35MPH. Airtabs are also effective at the rear rooflines of cars that have a rear window slope of greater than 30 ° Airtab improves vehicle stability by altering the airflow.How many Airtabs do you need? Measure the sides and roof of the vehicle. Place 3 Airtabs per running foot (4" on center) and spaced as shown.
