WORKING PRINCIPLES
An 8 Horsepower, four-cycle gasoline engine with a flexible coupling on its output
shaft is used to drive a positive displacement rotary-blower. The air entering the
blower is first filtered through a large stainless steel filtering element. The blower
supplies air pressure to the nozzle. The air pressure is adjustable between 2-6
PSI, 7 PSI max (0.14 – 0.41 Bar, 0.48 Bar max) by varying the engine speed
and/or by removing the air bleed orifice at the boom. The formulation is delivered
to the nozzle by means of a positive displacement diaphragm pump that draws
the formulation from the tank, through a filter and 3-way valve, and into restricting
orifice, solenoid valve and the nozzle. The nozzle has six stationary fins that
create a swirling effect of the air mass as it leaves the nozzle. In the center of this
swirling air mass is a liquid supply tube. The spray tube directs the formulation
into the air mass where it is sheared into billions of tiny droplets and dispersed
into the atmosphere.
This unit is equipped with a flushing system that is controlled from the manual 3-
way valve. The flushing liquid is conveyed to the nozzle in the same manner as
the formulation.
NOTE: The system must be flushed after each use.
