OPERATION AND ADJUSTMENTS
ARBUS 400Pressure regulator
• The nozzles have the job to generate
droplets and distribute them uniformly
over the surface being sprayed.
• Flow, angle and droplet sizes vary according
to working pressure. Operating with pressu-
re over that recommended by the manu-
facturer will decrease the nozzles’ life.
• This sprayer is equipped with alumina
(ceramic) nozzles, very resistant to wear
and to chemical action, and mounted as
shown in the figures below.
Nozzles
• The pressure regulator provides adjust-
ments ranging from 2 to 35 kgf/cm2 (30 to
500 psi), shwon by the pressure gauge (A).
• The lever (1) turns the chemical flow on
and off and the levers (2) controls the che-
mical flow to both sides or to one only.
ATTENTION!
To ensure longer life of the
pressure gauge, its valve should
be closed and without retained
pressure during the spraying.
After calibrating the sprayer,
use the lever (1) to release the
pressure in the circuit and close
the pressure gauge valve.
