The "Slim Jim" (SJ) model line is designed for narrow orchard and vineyard plantings as well as for our smaller hobby farmers and nurseries. More narrow than our SE model line, the Slim Jim is our narrowest model yet, with a 36-inch tank head diameter. Its sleek, compact profile delivers the performance you need for unbeatable results. Even our smallest models can be custom tuned to pull a 70 horsepower tractor to its knees, yet our standard fan only requires 35 horsepower. Air-O-Fan's steel axial flow fan, stator blades, and adjustable air vanes give our growers the performance they need to achieve exceptional coverage.
