Wind Diverter For Ventilation Fans
Wind blowing against a ventilation fan can create enough back pressure to slow or even stop the blade. The problem is generally greater in winter months when small or variable speed fans are operated at slow speeds.
To solve the problem, Agri-Aide Ventilation, of Glenwood, Minn., has introduced the Wind Diverter. The cone-shaped device, made of fiberglass, mounts in front of the exhaust opening to divert oncoming winds, yet doesn't alter the fan's normal exhaust capacity if mounted correctly, according to the manufacturer. The diverter can be installed on most horizontal exhaust fan hoods. To determine the correct size diverter to use, you measure diameter of the fan hood and add 2 in.
Wind Diverter kits in 8, 12, and 16 in. diameters sell for $26, $29 and $32, respectfully.
