RapidFire - Nozzle & Air Check
Test the air check nozzles for instantaneous
response at the nozzle tip. With the lines
at spraying pressure switch the nozzles On
& Off. Each nozzle must respond quickly
without dribbling, as the pressure builds up or
subsides.
The air checks Close under a spring tension
of 140 PSI. This traps the liquid in the spray
line at the same pressure that it was being
applied.
When the booms are turned On, air pressure
(acting against the 140 PSI springs) instantly
opens flow to the nozzle applying the boom
line liquid pressure at the rated pressure and
droplet size with full fan angle.
The air check valve is located on the side of
the nozzle, it has 2 O-rings in it. Over time, the
O-ring may swell or be damaged. This may
result in the nozzle dripping or being slow to
shut when it has been turned off.
If the nozzle leaks the outer O-ring requires
replacement. If the air shut off has poor or
delayed response, the inner O-ring requires
replacement.

3 Tier System - 3TS & 3TS
Pro (Options)
The 3 Tier System (3TS) provides a wider
range of flexibility with application rates and
spraying speed. The 3TS effectively gives
a much wider operating band whilst still
maintaining optimum droplet size.
The 3TS might be described as a three step
gearbox or in the case of the 3TS Pro, a seven
step gearbox.
3TS Option
Each nozzle type on 2 tiers has an operating
pressure band for a given droplet size. As the
first nozzle set or tier reaches the top of its
pressure band, the next larger size nozzle tier
is activated.
When the second tier reaches the top of its
pressure band, the first tier will be reactivated
to spray at the same time. This effectively
gives three operating bands.
Boom with 3TS Pro with alternating single & double nozzles
at 250mm spacing.
3TS Pro Option
The 3TS Pro option is an extension of this idea
using three different nozzle sizes and gives
seven effective bands of operation for even
greater application control.
It requires an unlock code for the Raven
RCM which is provided when the feature is
optioned.
The Raven RCM controls the 3TS system. For
specific calibration and operating instructions,
see Raven RCM operation manual supplied.
