Compressed air fan

NOTE

When the fan is operated with the tractor PTO shaft, excess grease can emerge from the drive bearings during the initial operating hours. A light film of oil is formed after the initial warm-up. After that, grease or oil may no longer emerge.

The compressed air fan 1 produces overpressure, which causes the seed grains to adhere to the singling discs. Depending on the equipment, the fan is driven by the tractor PTO shaft or a hydraulic motor. The overpressure is set through the fan speed. Depending on the implement equipment, the overpressure is displayed by a pressure gauge or the control terminal.
