QUANTUM MIST QM420 SPRAY “FAN”
Standard on all QM-420 models is the new extremely
efficient 420 mm diameter “QM-420” fan and the “Fan
Frame” mounting system.
Fan / Cap / Cover
The robust 5 bladed fan also features a separate
moulded front cap designed to prevent the build-up of
detritus so common in other fans, and the same cap, with
the “knockout” removed, is used at the rear to further
streamline the airflow.
Drive Body
The drive body differs from the “original” and very reliable
QM-380 drive body in that it has a further 4 tapped holes
to accept the rear cover. Note the rear cover (which is
the same moulding as the front cap, with a knock out for
the hydraulic motor) has positions for 5 screws, but only
4 screws are used. The “5th screw” position aligns with a
casting cutaway for either a speed sensor or case drain
connection (see photo above).
Cowl Orientation / Speed Sensor / Case drain
The cowling should always be mounted with the cutaway
for speed sensor or case drain facing downwards (to
enable drainage). The case drain is there for the unlikely
event of blowing oil seals in the hydraulic motor.
Sprayers fitted with the optional Wind Compensation
feature will use two speed sensors (left and right).
Note the rear guard needs to be removed to fit or access
the speed sensor. Replace the guard once done.
Dual Spray Rings
The fan also features twin spray rings, with 5 nozzles
per ring. This allows unprecedented control over spray
coverage rates and droplet spectrums.
As supplied ”standard”, it’s set up as a 3-tier system. The
inner / smaller diameter spray ring is fitted with a smaller
(brown) nozzle, and the outer / larger diameter spray ring
is fitted with a larger (yellow) nozzles.
• Inner spray ring only is Tier 1 / lowest volume rate.
• Outer spray ring only is Tier 2 / medium volume rate.
• Both spray rings together are Tier 3 / for high volume rate.
There are many other ways to use the dual ring system such
as using one of the rings for special purpose nozzles.
See pages 30 & 31 for more information on Tiered plumbing.

Hydraulic Drive
All QM-420 fans are driven by hydraulic motors built to a
special heavy-duty specification and with case drain port.
Most QM-420 models are fitted with 6.5 cc hydraulic
motors. In some instances (if required) 9.8 cc motors
are used.
Guards
The QM-420 must never be used without the front and rear
guards installed.
Operational limits
The nominated maximum operating speed of the fan is
3,000 rpm. Normal delivered maximum operating speed
of 2,500 rpm. Exceptions apply.
DANGER, Stay well away from rotating fans.
Whilst the front (downwind) side may appear to be the
more dangerous side, it’s the back side that holds greater
danger as it can suddenly suck body parts or objects in.
Fan Frame Mounting
Each spray fan is mounted via dual M12 brass inserts
moulded into each side of the cowling.
The normal spray fan mounting method is via special
stainless-steel clamps into the “Fan Frame”.
The bracket is reversible and can be used to adjust fan
positioning (see more on page 50).
U-Bracket Mounting
As used on the 1000 Lt trailed sprayer and….
• where the QM-420 is being retrofitted to replace older
QM-380 fans (now discontinued)
• the fan is being fitted to a “Classic” style sprayer which
uses hook brackets rather than fan frames...
… the fan can be mounted via a fabricated, black powder-
coated steel U-bracket (HP-319-8) to the HP-275C scissor
action clamp.
Also requires the HP-275C-1 clamp plate.
Leaf Guard
A moulded leaf guard is fitted as standard to all bottom fans.
Check Valve/stop cock/drain
The feed to each spray ring is fitted with a “non-drip”
diaphragm check valve with an integral stop cock
which allows individual spray rings to be manually shut off
as required.
Screw the red cap in for stop, out for normal diaphragm
“non-drip”.
Each spray ring has a draining/flush tap on the exit.

FAN FRAMES, BOOM ARMS & TIE RODS
Fan Frames
Mounting the spray fans into the fan frames has many
advantages, including the ability to specify the exact
positioning of fan heights and angles. The fans remain well
protected and fixed until a change is required.
Up to 3 fans can be installed in each fan frame – with the
lower fan also using a leaf guard.
All outer row fan frames incorporate a breakaway system.
Detailed information regarding setting up and
operating the fans (and booms) in Section 5.
Over-row Boom
Over row booms use a sliding carriage (A) connection to
the fan frames and incorporate a breakaway system.
The outer underside of each boom arm has 3 holes (B) set
at 300m intervals into which the sprung loaded pin (C)
can be engaged. This sets the row width.
NOTE - If fitted with Optional Hydraulic outer row width
adjustment the manual locking in is not used.
The optional hydraulic outer row width function does not
require the slide locking mechanism.
The slide has several nylon buttons within the carriage to
aid smooth operation. The buttons are adjustable to allow
for wear – the buttons and adjustment bolt with lock nut
can be seen in the photo below.

PRODUCT FEATURES / FAMILIARISATION
Spray fans in the boom open position are at right angles
to the sprayer. For parking, the fans can be manually
rotated via the connection swivel (D) to one of 3 positions
(nominally 74, 90 or 104 degrees) so that the fans can
park flat against the sprayer for transport. The 3 positions
can be seen in the last photo previous page.
3-Row sprayers use the same sliding carriage
arrangement. Only the outermost carriage is locked into
place with a tie rod connection between both slides. This
ensures both frames remain sufficiently separated (when
rotated for parking) and will move together when row
width adjusted.
The optional hydraulic outer row width function also
requires the tie rod between both slides to ensure both
frames move together.
Single row/Rear Fans
Most models of the QM-420 Sprayers connect the rear fan
frames to the main tower via a pair of “standoff” brackets
and saddle clamps.
The standoff brackets can be moved in both height and
rotation by loosening the saddle clamps at (A) and rotate
the required width – retighten. Then adjust the fan frames at (B) to spray to the required
direction (normally square to the canopy.

Tower options
All boom arms connect to a Tower, of which there are
multiple variations.
• Standard Tower (the standard tower is recommended for
use in vineyards with row widths from 2.5 to 3.0 metres).
• Wide Tower, has an extra 400mm each side.
The wide tower option (shown by yellow arrow) is
recommended for use in vineyards with row widths
from 3.3 -3.6 metres. This design reduces the boom
arm length thus aiding more clearance for 3-row
sprayers in the parked position.
• Tall Tower (400 higher and uses longer fan frames).
• Tall (wide) Tower.
• Terracing Tower. The terracing tower has 600mm
of movement. Both the left and right sides can be
moved independently. All fans on one side move
at the same time.
• Wide Terracing Tower.
• Tall versions of both terracing towers are also available
as special builds.

BOOM CONTROLS/HYDRAULICS
All boom fold functions are (standard) via tractor hydraulic
remotes.
However, a fully optioned sprayer will have too many
boom functions for operation via the available tractor
remotes. Tractor remotes #1 will often be for fan
hydraulics.
Possible boom functions are (also see photo previous
page):
• Left arm fold
• Right arm fold
• Left terracing lift
• Right terracing lift
• Left row width adjustment
• Right row width adjustment
If the diverter (HT-EDV option) is available where only one
remote is available for 2 functions
Eg. say left and right fold, to flick between these operations.
If the diverter valve option is not sufficient, the only choice
is to use the multi-function electric/hydraulic switch box to
control boom functions via multi-function Cetop valve block
at the rear of the sprayer.
Hydraulic Identification
All hydraulic hose circuits are identified as per below.
Some exceptions apply for special builds.
(A) Pressure hoses to have two colour bands
(B) Return lines to have one colour band

FAN HYDRAULIC SYSTEM
There are 2 different fan hydraulic systems available.
(a) The Standard conventional hydraulic system as
used on Quantum Mist sprayers for many years, with
several improvements, and …
(b) The “A3 WindComp” system. The A3 system is
only used on the QM-420 sprayers with the optional
WindComp feature.
In both systems, the general fan motor plumbing is the
same. The fan hydraulic motors are plumbed in series of 2,
3 or 4 fans per circuit. As well as pressure in and out, each
motor is plumbed with a case drain, also plumbed in series.
In some cases, each set of fans per fan frame is a
separate circuit.
Oil returns from the fans go via the distribution block, then
via the oil cooler (if fitted), and finally back to the tank (be
it the tractor or power pack).
