Airtab^® is a registered trademark of Aeroserve Technologies Ltd. US and Canadian Patents.

Airtab® Fuel Savers are patented, unique wishbone shaped vortex generators designed to increase vehicle aerodynamic performance and fuel economy by reducing aerodynamic pressure drag at two key locations; the tractor-trailer gap and the rear facing surface (the base area) of any commercial or private square backed vehicle or trailer that routinely attains highway speeds. Drag reduction and fuel economy benefits from Airtab® application is not limited to commercial trucking operations. Airtabs™ enhance aerodynamic performance equally well on cube vans, straight trucks, expeditors, SUVs, RVs, buses, horse, toy and utility trailers, faired, bob tailing tractors, flat beds and tankers. Airtabs™ work in concert with existing air management kits.  The results may vary somewhat with vehicle type but the aerodynamic theory and principles are the same for all.

Airtabs™ are not about boundary layer modification, attached flow issues, flow separation prevention or lift generation. Airtabs™ work by altering the near wake free stream airflow at any vehicle trailing edges. The benefits stem from the airflow behavior in the wake area after it has separated.

Airtabs™ are quick and easy to install, and are mounted 3 per linear foot, or every 4 inches on center. Take the number of feet to be covered and multiply by 3 to give the number of Airtabs™ required. Airtabs™ are approximately (in inches) 3.5 wide, 5 long and 1 high.

Each Airtab® creates two counter rotating solid body vortices that combine to reduce drag at vehicle rears and at tractor/trailer gaps.  Airtabs™ are also effective at the rear roof lines of automobiles that have a rear window slope of greater than 30 degrees.

Airtab^® Fuel Savers offer several safety benefits as well. They improve vehicle stability by altering the airflow at the vehicle's rear. The large random eddies at the rear surface are changed to an array of small vigorous "stream wise" vortices. The majority of users comment immediately on the improved vehicle handling performance, especially in gusty cross wind conditions or when passing (or being passed by) other vehicles. This increases driver safety margins by reducing wandering and sudden adjacent lane incursions. Mirror visibility in rain or snow is also improved as the Airtabs™ help suppress precipitation and spray patterns. Safety is improved through better mirror visibility yielding safer lane changes as well as improving the visibility conditions for other road users. By reducing the suction and aerodynamic drag at the rear of vehicles, the tendency to accumulate snow and road grime at this location is reduced. This helps to improve corporate image and reduce cleaning time and expense. It also enhances safety by keeping conspicuity tape, tail and brake lights cleaner and helps the bottom line by reducing snow and weight build up in winter.

Airtabs™ were designed with safety and performance in mind. Hollow construction allows them to crush if run over. Their smooth "user friendly" curves make Airtabs™ safe and easy to handle. They will not cut, snag clothing or fingers, catch ropes or straps, snow, insects, branches or vegetation. They install using integral double sided "Peel & Stick" tape…no messing with separate tape pieces or templates, no glue, no drilling and no penetrating bolts, rivets, brackets or screws.

Airtab^® Fuel Savers meet vehicle width regulations (Click here to view regulations). (4.76" long, by 3.25" wide, and stick out only 1")  The Airtab® shape has been tested in test track, wind tunnel and over-the-road evaluations.

Airtabs™ are now in use around the world and have withstood scrutiny in many different markets and applications. Airtabs™ have been imitated but never duplicated and have garnered accolades from both NASA and our customers for simplicity, performance efficacy, safe practices compliance and innovation.
