7 FT Diameter, 3 Point Frost Protection Fan

"Put air where you need it... when you need it."

Protect up to ten acres of fruit or vegetables for pennies per hour. By using our SEVEN FOOT DIAMETER frost fan directly on your tractor's P.T.O. you can greatly increase your natural air drainage. With three point hitch mounting, this unit can be moved to protect whichever crop is most critical at the time. 

The placement of this fan in lower areas or valleys of your orchard or fields will push the colder, stagnant air out, forcing its replacement with warmer air from higher levels. The effective coverage area will be approximately 500 ft. wide and 1/4 mile long.

This area of increased temperature will include all the low area on both sides, behind and in front of the fan.

5 ft and 7 ft Fans available.

5 FT fans require a minimum of 60 PTO HP to maintain 540 RPM. Lower RPMs will require less HP, but will reduce the air moving capability. This diameter fan will move approximately 400,000 cfm of air. This number includes all the air surrounding the fan, not just through the venturi.

7 FT fans require a minimum of 80 PTO HP to maintain 540 RPM. Lower RPMs will require less HP, but will reduce the air moving capability. This diameter fan will move approximately 700,000 cfm of air. This number includes all the air surrounding the fan, not just through the venturi.
