Double screw movement
As shown in the picture on the side, it is possible to manu-
ally adjust the angle of the double screw delivery head in
the illustrated positions.
ATTENTION
This adjustment can only be performed with the
impeller stopped and for no reason can anyone be
present in the machine’s operating range if equipped
with PTO transmission and rotating impeller or if you
act on the controls on the driver’s seat!
For illustrative purposes only it is shown the hypothetical
interchangeability between cannon and double screw.

The main characteristic of this type of fan unit, is the abil-
ity to suck the air from the front and from the back. It is
formed by two counter-rotating rotors with nylon blades
and the transmission is with quick release overdrive.
The structure and conveyor are coated (Pic. 115). This
type of fan unit has been specifically designed to protect
tree crops with espalier, in fact it can reach the top of the
highest rows, up to 8 metres.
