1.0 INTRODUCTION
The Micron TURBOFAN Sprayhead has been developed from over 30 years experience
in the design and use of rotary atomisers. Originally developed for agricultural aircraft,
these atomisers are now used for aerial and ground applications in more than 75 coun-
tries. This unique background, combined with continuous research and development, has
enabled Micron to produce a truly versatile and reliable sprayhead for almost every agri-
cultural spraying requirement.
The Micron TURBOFAN sprayhead uses a rotary atomiser, mounted in a protective cowl
and driven by a compact hydraulic motor. The atomiser uses a stack of toothed discs to
break the spray liquid into precise oversized droplets. This unique approach ensures that
all of the spray volume is concentrated into a narrow range of droplet sizes.
The atomiser also incorporates an axial fan which produces a turbulent, swirling air-
stream from the sprayhead. This carries spray to the target, disturbs foliage and ensures
good penetration to give an even coverage in dense crops.
The Micron TURBOFAN Sprayhead operates over a wide range of liquid flow rates,
enabling the same unit to be used for ultra low, low and higher volume application. The
atomiser is designed to handle all types of liquid formulations from specialised ULV
products to high concentrations of emulsifiable concentrates and solids in suspension.
The Micron TURBOFAN Sprayhead is ideally suited to most spraying tasks, whether in
fields, bushes, orchards or vines. Whatever the application, the combination of con-
trolled droplet size, wide range of application rates and air assistance will enable the user
to achieve improved spray coverage and control with a minimum wastage of chemical,
thus ensuring the best possible biological results at a minimum cost.
Should field service be necessary, the simple design of the sprayhead enables it to be dis-
mantled and cleaned in minutes.
TURBOFAN sprayheads require a hydraulic oil supply to operate. This can often be pro-
vided by the tractor or vehicle’s own hydraulic system. Alternatively, it may be neces-
sary to install an auxiliary hydraulic system with its own reservoir and power driven hy-
draulic pump.
Because of their versatility, TURBOFAN Sprayheads can be installed on a wide range of
sprayers. These may be specially built or may be conversions of existing machines.
Through its own experience and that of its customers, Micron can advise Original Equip-
ment Manufacturers (OEMs) on the design and construction of most types of sprayers.
