Reversible Fan Blades Keep Radiators Clean

Reversible Fan Blades Keep Radiators Clean TRACTORS Modifications 24-5-13 Modern tractors can have as many as five radiators lined up in a row which requires fans with a very high air flow. This causes a strong vacuum effect which can result in clogged air-intake screens and radiators. A new fan with reversible blades is designed to solve the problem. Made in Germany and sold in North America by Sunova Implement, the Cleanfix fan simply bolts on in place of the original fan. By flipping a switch, the operator can change the angle on the fan's blades. A small 12-volt air compressor is used to change the pitch of the blades by 90 degrees. You can do it manually or the fan can be set on a timer to periodically reverse itself. "It helps stop overheating on tractors, combines, self-propelled forage harvesters, etc.," says John Van Lierop, Sunova Implement Ltd., Lakeside, Ontario. "The timer can be set to operate at anywhere from 10 to 60-minute cycles, with the duration of the cycles ranging from 10 seconds to 3 minutes. "A universal adapter flange allows the fan to fit 90 percent of all farm equipment." Several different sizes are available. A mid-sized model sells for $1,850 U.S. The electronic timer sells for $100 to $150 depending on whether it's 12 or 24 volt.
