Pneumatic spray system
The pneumatic system is low pressure. This system takes advantage of
the high air speed in the spout outlet to break the spray liquid and give
a very fine mist together with turbulence. Using the deflectors at the
spout outlet, the mist means that the liquid is 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 Paraflow 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 fine mist together with turbulence. Using the deflectors at the tube outlet means
that the liquid is distributed uniformly.
There are two Paraflow models, which cannot be used together,
according to the bar type and assembly requested for the machinery:
Paraflow tube with 4 in-line atomizers
Paraflow tube with 6 in-line atomizers
ATTENTION! Ceramic nozzles are used for the standard
pneumatic system and the paraflow system. This type of nozzle
has two positions. If the nozzle is fitted so that the flow enters
on the flat side, less flow 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 five 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.
