Wingman, the air flow control product from Airman Inc., now guarantees a 5% miles per gallon increase or Airman Inc. will buy the Wingman back.

Wingman's operational features include superb ground clearance, high trailer stability in cross winds, spray control in wet weather which provides excellent, clear views on both sides of and behind the trailer, cooler running tires and brakes, while greatly reducing trailer seeking for a much easier pull.

Wingman is tucked in next to the rear axles and moves with the axles. Wingman's compact design prevents damage from curbs, railroads, or large elevation changes in skirt-unfriendly docks.

Because Wingman is so short, under-trailer access is not impeded. The product's design also provides constant mileage benefits for all axle configurations, according to the company.

"Airman is so certain that your rig will get at least a 5% miles per gallon increase that we are offering to repurchase any non-performing Wingman we installed on a clean bottom 53-foot regular trailer," says Bob Henderson, Wingman inventor and CEO of Airman Inc.
