FAQ - Nose Fairing and Vortex Stabilizer
Q. How does it work to save fuel?
A. The devices are designed to create low air pressure on either side of the trailer. As air tries to cross the trailer face at high yaw angles, it is redirected back down the side, stopping it from going through the gap and releasing from the downwind side. This improves laminar flow, which requires less horsepower and thus saving fuel.
Q. How much fuel savings can I expect?
A. Depending on the angle of the wind and speed traveling, one can expect between 2 to 3 per cent fuel savings. This is in addition to fuel savings achieved when also equipped with a LCL trailer fairing. Tested at the A.R.C. wind tunnel.
Q. How does the nose fairing or vortex stabilizer fasten to the trailer?
A. For the nose fairing - mounting brackets are bolted through the front trailer face, drilling is required, and into the internal vertical channels. The nose fairing is then bolted to the mounting brackets and inside flanges.
For the vortex stabilizer - no brackets are required, the unit comes with a wide flange which is bolted directly to the front trailer face, drilling is required.
Q. How long to install?
A. One to two hours for the vortex stabilizer and two to four hours for the nose fairing depending on the trailer front face construction.
Q. Will it interfere with my roof fairing and cab extenders on tight turns?
A. NO - the vortex stabilizer is centered down the middle of the trailer face and provides ample clearance. The nose fairing requires a minimum clearance of 42 inches from the existing trailer face to the back of the cab.
