The gear box situated in the air kit is one of the mechanical elements which works the most. The P540 (22”) air kits on the
Zenit sprayer are equipped with two speed gear boxes.
Gear box
The gear box for the P540 (22”) air kit has two speeds. The speed
ratio is as follows:
P540
1st speed = 1/5.7
2nd speed = 1/6.6
The capacity is 59 oz. (1.75 Liters) of oil for cooling and lubrication.
Use synthetic SAE 30 oil.
See “Maintenance” for how frequently the equipment needs to be
checked.
The pneumatic system is low pressure and takes advantage of the high air speed in the spout to break up the spray film
and create a very fine mist that includes some turbulence. The atomizers in the spout spread the mist uniformly in the
shape of a fan.
Pneumatic system
There are four types of spouts which make up the boom configura-
tion you may have on your sprayer.
A - Cannon with one outlet.
B - Spout with 2 outlets.
C - Spout with 3 outlets.
D - Spout with 4 outlets.
ATTENTION! For this system, ceramic discs are used to deter-
mine the flow rate. This type of disc has two possible posi-
tions. If the disc is placed so that the flow goes in through the
cone-shaped side, the nozzle will give out more flow than if it
is placed so that flow goes in through the flat side.
