Air kit
Axial fan – Technical information
The fans on HARDI ZENIT mist blowers have been designed with composite blades and their aerodynamic design
offer a higher quantity and better distribution of air, less noise and less power consumption. They are also fitted with
a centrifugal clutch so as to start up and stop in a smooth way.
Flow levels go from 35,000 to 45,000 m3/h depending on the adjustments made to its components.

The tractor P.T.O. should not exceed 540 rpm as there is
grave danger that the air kit may explode.
Keep away from the air inlets and outlets while the fan is
on. Some objects may be expelled from the air outlet or a
piece of cloth could be sucked into the air inlet.
The air kits are the most dangerous part of the machine. Do not
try to change any of the parts without consulting your nearest
dealer beforehand. Handling air kits in order to change their cha-
racteristics should be done by qualified people.
Adjusting the fan
The angle of the fan blades can be adjusted to 4 positions. They
normally come in position 3.
Decreasing the angle of the blades (minimum angle, position 1)
lessens the flow and decreases power consumption. By increa-
sing the angle (maximum angle, position 4) the flow increases,
but so does power consumption. In this way the mist blower can
adapt both to the different applications as well as the power of
the tractor.
To change the position of the angle of the fan blades you should
follow these steps:
1. Take off the suction grid.
2. Loosen the Allen screws
pletely.
3. Loosen the Allen screws
4. With both hands on opposite blades, turn them to the position wanted between 1 and 4. All the blades should
turn at the same time.
5. Finally, check all the blades are in the same position .
