Reduce aerodynamic drag


The Trucking Industry's First Totally
Automated Trailer Air Spoiler

The SmartTail® aerodynamic fuel $ saving Air Spoiler is a rugged polymer skin transforming the trailer’s rear into a
more optimized aerodynamic profile to reduce drag and air vortex disturbances at the rear of the trailer.


SmartTail is Deployed or Stowed

Smart Control

  • Smart Control is a self-contained state of the art control. It includes air blowers and a simple micro-computer and GPS. Speed, altitude, temperature, pressures and direction are monitored to automatically inflate and deploy the SmartTail® polymer skins while at higher speeds.
  • When low speeds are sustained for a time period, the control will automatically deflate and create a vacuum within the polymer skins to stow them, allowing the driver to simply open the rear doors normally without any additional duties
  • Contained within a rugged Stainless Steel frame that is easily mounted to the rear underside of the trailer
  • Only connection is to the trailer’s 12 volt circuit (no air or any other connection required)
    • Normal load is less than 100ma with 5 amp peak demand.
  • Control goes to sleep when tractor connection is powered off.
  • Unique features include automatic stowing if reverse direction of trailer is detected.
    • Eliminates any additional driver duties if backing into docks with rear doors closed.
