Pneumatic spray system

The high air speed in the spout breaks the spray liquid and gives a very
fi ne mist together with turbulence. Using the defl ectors at the spout
outlet permits the mist to be distributed uniformly.
There are four spout models, which can be combined according to the
bar type and assembly requested for the machine:
A. Cannon with 1 atomizer
B. Spout with 2 atomizers
C. Spout with 3 atomizers
D. Spout with 4 atomizers
The Parafl ow pneumatic system is low pressure. This system takes advantage of the high air speed at the pipe outlet to
break the spray liquid and give a very fi ne mist together with turbulence. Using the defl ectors at the tube outlet means
that the liquid is distributed uniformly.
There are two Parafl ow models, which cannot be used together,
according to the bar type and assembly requested for the machinery:
Parafl ow tube with 4 in-line atomizers
Parafl ow tube with 6 in-line atomizers
ATTENTION! Ceramic nozzles are used for the standard pneumatic
system and the parafl ow system. This type of nozzle has two
positions. If the nozzle is fi tted so that the fl ow enters on the fl at
side, less fl ow will be allowed than on the conical side.

Hydropneumatic spray system

The hydropneumatic system is medium-high pressure. This system takes
advantage of higher turbulence in the low-volume conical nozzle and
sprays the liquid with an even distribution. The air reaches high speed in
the spout, spraying the liquid in a fan.
There are three spout models with three or fi ve nozzles. These two
models cannot be combined.
E. Spout with 3 nozzles.
F. Spout with 5 nozzles.
Where not all the nozzles are required in treating the crop, the nozzles
can be replaced for caps.
