Spraydown Aero Guard System, a three-dimensional mudflap brought to the U.S. commercial vehicle market in 2010 through a strategic alliance between Spraydown USA and Betts Spring, is showing positive results in fuel savings, spray suppression and reduced emissions during fleet road trials, track and laboratory testing in Europe, according to Spraydown. Spraydown USA products are manufactured domestically by Engineered Profiles at its facility in Columbus, Ohio.

The vertical aero vanes manufactured into Spraydown mudflaps are designed to redirect spray down through the pockets, smoothing airflow and reducing drag, resulting in fuel savings. According to the company, safety is enhanced because 98 percent of spray is directed back to the road and out of the driver’s view.

Spraydown says that since the product was introduced in Europe more than four years ago, more than a million miles of vehicle on-road and track testing has been performed. The company says the results, supported by research and laboratory testing, indicate an improvement in fuel economy in the range of 1.5 to 3 percent by replacing standard mudflaps with Spraydown Aero Guards; testing also showed 95 percent suppression of spray from vehicles outfitted with Spraydown.

Spraydown Aero Guards are available in 24-inch, 27-inch and 30-inch lengths in both straight and angled-down configurations and are designed for easy installation.
