DRAFT 2 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 f or agricultural aircraft, these atomisers are now used for aerial a nd ground applications in more than 75 coun- tries.
DRAFT 3 2.0 SPECIFICA TION Length (max. front to back): 35 cm (complete with mounting bracket) Diameter: 45 cm Weight: 6.4 Kg plus mounting bracket 1.7 Kg Liquid flow rate: 0.25 – 2.0 l/min Spray droplet size: 100 – 120 microns VMD Hydraulic oil flow: 8 l/min per sprayhead.
DRAFT 4 3.0 TEN KEY POINTS FOR USERS The following list of ten points is intended to assist users in the efficient use of Turbofan sprayheads. It is hoped that this section will encourage users to read the entire handbook and follow its recommendations.
DRAFT 5 4.0 INST ALLA TION The design of a sprayer incorporating Turbof an Sprayheads will va ry according to the crop to be sprayed, the type of sprayer being used and the available hydraulic power. This section gives general advice and design da ta but is not intended to provide specific instructions for buildin g ever y type of sprayer.
DRAFT 6 4.1.1 Distance from Crop Each sprayhead must be positioned sufficien tly f ar from the crop to allow the airflow from the fan to disperse the spray droplet s over a wide band and to prevent local over- application of fo liage close to the atomiser.
DRAFT 7 IMPORTANT: Sprayheads must never be posi tioned so that spra y droplets can be blown towards the driver or opera tor of the sprayer. Ensure that all spray is blown clear of the sprayer structure to eliminate contamination and run-off.
DRAFT 8 4.2.2 Parallel Connection The hydraulic motors of the Turbofan are normally connected in parallel. To calculate the hydraulic flow require d for a specific number of heads :- • each head runs at 4000 rpm • the oil flow required per moto r is 4000 x 2ml/rev = 8 1/min • add 10% for pump and other hydraulic losses = 8.
DRAFT 9 4.2.4 Hydraulic Oil Flow If a Power Take Off (PTO) driven hydraulic pump is used, the pum p should be chosen to provide the calculated maximum oil flow plus losses and no more. If a larger pump were to be used, any unused oil would have to be by-passed and would generate heat.

DRAFT 12 4.2.7 System Protection Any self-contained hydraulic system MUST be protected by a relief valve from the pres- sure side of the pump to the reservoir. Th is should be of the self re-setting type. • For parallel running this must be set to 120 bar (1800 PSI) minimum.

DRAFT 15 4.2.13 Filter All hydraulic systems MUST be filtered. For sprayers using the tractor’s hydraulic sys- tem, a return line filter with a 25 m icron re placeable cartridge and a full-flow by-pass re- lief valve should be fitted in the retu rn line to the tractor.
DRAFT 16 If a new sprayer is being desi gned or an original pump is to be replaced, it is suggested that a diaphragm or centrifugal type is chosen. This should be able to provide a pressure of about 1.
DRAFT 17 4.4 Testing Any new sprayer must be tested to ensure the following: 1. That the sprayheads all rotate at the correct speed. 2. That the chemical flow from each sprayhead is equal and that the f low can be adjusted over the fu ll range required.
DRAFT 18 and the coverage assessed viewing the droplets with an ultra-violet lamp in the dark. 5.4 Sequence of Operation It is important that all s prayheads are rotating at their correct speed before the chem ical supply is turned on. Similarly, the chemic al supply m ust be shut off before the sprayheads are stopped.
DRAFT 19 The following recommendations are for guida nce only and do not ex clude any statut ory requirements: 1. Always wear adequate protective clothi ng, eye protection and re spiratory protection when mixing, transferring or spraying pesticides.

Establish the average forward speed of th e sprayer. The most accurate means of assessing the speed is to drive the sprayer in the actual crop.

DRAFT 23 8.0 MAINTENANCE The Turbofan Sprayhead is manufactured from high quality materials which have been selected for maximum strength, reliability an d resistance to agricultural products. In order to ensure a long and trouble-free working life, it is important that each sprayhead should be periodically checke d, cleaned and lubricated.
DRAFT 24 1. Disconnect all hoses and rem ove sprayhead from the spraye r. Plug all free ends of hydraulic hoses on the sprayer and all ports on the hydraulic motor.
