Air-O-Fan Orchard PTO Sprayers - GB-2/32

The Air-O-Fan GB-2/32 500, 600, & 1,000 Gallon orchard sprayers out-perform, out last, and out sell other similar sprayers in it's class. The goal behind running twin fans is to create a high volume of turbulent air, this tumbling high volume of air is created by twin fans (one with reverse pitch) colliding air together to charge the fan housing into a larger discharge throat which in turn creates a higher volume of tumbling turbulent air. This technology is very popular in crops that are close to the sprayer, dense in nature, and range in heights up to 30 feet; such as citrus, almonds, olives, & even Walnuts. The GB-2/32 model line is the next best thing to an engine driven sprayer if the proper tractor horse power is available (90 PTO horse power minimum is required). Our adjustable air vanes give controlled direct coverage which reduces drift and saves time and chemicals while utilizing a dual bank of nozzles in the air stream to give the applicator more calibrating options without having to remove nozzles. This can benefit coverage by allowing the applicator to use more water droplets at the same calibration rate or by allow calibrations to be set for concentrate or dilute applications. Lastly our "Twin Fan" model comes standard with our DK turning hitch, Comet APS-141 diaphragm pump, AOF suction filter assembly, heavy duty manifolds, rectangular tubing chassis, and our industry leading steel axial flow fan(s) assembly, as well as a full line of options including or 2-point turning hitch option, dry cam-lock quick fill systems, tree targeting and rate controlling systems, multiple tire options, and our Myers ® 2-stage centrifugal pump option.
