Compressed air fan

NOTE

When the fan is operated with the tractor PTO shaft, excess grease can emerge from the drive bearings in the initial operating hours. A light film of oil is formed after the initial warm-up. Thereafter, grease or oil must longer emerge.

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