DESCRIPTION
The ELECTRAFAN 12 is a light air-assisted hand-held spinning disc Controlled
Droplet Application (CDA) sprayer. It is powered by a 12 volt DC battery, with Mi-
cron’s rechargeable battery giving about 1½ hours spraying before recharging is re-
quired. The sprayer is designed for intermittent use. The sprayer with a full spray
bottle weighs 3.25 kg, and the Micron battery weighs 6.6 kg. An electric motor spins
the atomiser disc to produce uniformly small droplets which are carried to the target
by the airstream generated by the fan. Liquid is fed by gravity. The ELECTRAFAN
12 is designed primarily for the foliar application of insecticides and fungicides in
glasshouses and polytunnels of both water-based mixtures (e.g. ECs, WPs) at 20 to
40 litres/hectare total spray volume and Ultra-Low Volume (ULV) formulations. It is
also used to apply public health insecticides, for applying vaccines to poultry and for
insect control on livestock and in animal housing. When using the ELECTRAFAN
12 in an enclosed/confined space a full face shield and respirator must be worn (see
‘OPERATOR PROTECTION’).

OPTIONAL EXTRAS
2
Micron offer an optional 12 volt DC rechargeable battery and special safety re-
charger. It is a sealed lead acid 17Ah (amp hour) battery fitted into a nylon case with
a shoulder strap. An in-line 10 amp anti-surge fuse is fitted (see ‘THE BATTERY’).
SAFETY
Using agrochemicals is a hazardous process, particularly in enclosed areas.
Operators should comply with all relevant legislation and/or regulations governing
the use of agrochemicals and must use appropriate personal protective equipment
(see ‘OPERATOR PROTECTION’). Never use the ELECTRAFAN 12 in
potentially explosive atmospheres or spray flammable liquid through it.
The ELECTRAFAN 12 can be used with most conventional insecticides and
fungicides, as well as specific ULV formulations (only available in some countries)
which reduce risks in mixing and filling.
Always read the product label carefully to
discover:-
approved applications
maximum dose rates
maximum number of treatments
operator protection required
necessary environmental protection
measures
N.B. ‘Dose rate’ refers to the amount of chemical product applied per hectare.
Never eat, drink, or smoke when working with agrochemicals. After using
agrochemicals or handling equipment wash your hands thoroughly. Keep people
(especially children) and animals out of areas being sprayed.
Always store agrochemicals safely to protect people and animals, and to safeguard
the environment (take special care to avoid water pollution). See spraying sections
for guidelines on safe use of the ELECTRAFAN 12 in operation.

OPERATOR PROTECTION
Always wear the protective clothing items listed on the product label for mixing and
filling. The minimum protective clothing required for spraying with the ELEC-
TRAFAN 12 is:
face shield
respirator
rubber gloves and boots
long sleeved shirt
long trousers
Note:
a) Acoustic information: the sound pressure level at the operator’s ear is 84 dB
(A). Using the machine in an enclosed/confined space may cause this level to
increase by up to 6 dB(A). The sound power level of the machine is 87 dB
(A).
The wearing of suitable ear defenders is recommended when using this ma-
chine.
b) Vibration: the weighted RMS acceleration value at the hands when using this
machine is 6.3 m/sec².
Always disconnect the sprayer from the battery before servicing or following
‘TROUBLESHOOTING’ procedures.
Never touch the edge of the atomiser disc.
Never insert anything through the fan guard with the machine connected to the bat-
tery.
Never wear loose clothing, e.g. scarves and ties, or any item which could be drawn
into the fan.
Check the sprayer cable frequently for cuts, abrasions and damage. A faulty cable
must be replaced.

PREPARING FOR SPRAYING
Before connecting to the battery, check by hand that the atomiser assembly and fan
rotate freely by turning the atomiser assembly in an anti-clockwise direction. (Do
not touch the edge of the atomiser disc). If they are not free to rotate do not attempt
to start the sprayer but contact your supplier or Service Department at Micron.
Plug the sprayer into the battery and switch on to check smooth running of the atom-
iser disc and fan.
The sprayer must only be used at the rated voltage. The machine must be switched
off in the event of power interruption.
N.B. Before spraying for the first time with the ELECTRAFAN 12, sprayer opera-
tion must be checked using only water (see ‘BEFORE SPRAYING’).

MIXING, FILLING AND CALIBRATION
Mixing and filling is generally the most hazardous process in the spraying operation.
Always follow the label instructions. Always use a funnel when filling the bottle.
Only mix enough spray for the area to be treated if using water-based mixtures to
avoid the need for disposal of unused spray mix.
Always wear gloves when handling
agrochemicals and equipment.
Always use the correct equipment
when mixing and measuring.
Always wash off any skin
contamination
Always clean all equipment after
use.

ULV FORMULATIONS
ULV formulations will have full instructions for use on the label.
WATER MISCIBLE PRODUCTS
Traditional water miscible insecticides and fungicides are usually applied with the
ELECTRAFAN 12 at 40 litres total spray volume per hectare. Most insecticides can
be used at 20 litres/hectare but fungicides may require around 40 litres/hectare. For
example, if the label recommends applying a minimum of 2 litres of insecticide
product made up to 100 litres of water per hectare with a conventional sprayer, use 2
litres of product made up to 20 litres for application with the ELECTRAFAN 12, i.e.
a spray mix concentration of 10%.
Do not use product concentrations greater than the maximum recommended on the
label (unless specific training or recommendations have been given) if the label:
a) specifically prohibits use of ‘Reduced Volumes’ i.e. increased concentrations;
b) has a statutory requirement for use of personal protective equipment when using
the diluted product at high volumes (N.B. this will appear in the statutory box on
the label); or
c) carries one of the following hazard ratings: ‘very toxic’, ‘toxic’ or ‘corrosive’ or
carries the warning ‘risk of serious damage to the eyes’.
Micron do not generally recommend using spray mixes more than ten times the
maximum concentration recommended for high volume application. At high
concentrations some products can be phytotoxic to crops. Thus, if in doubt, first
spray a small test area. Do not use more than the minimum recommended label
dosage rate i.e. where the label recommendation gives a range of dose rates of, for
example, 2 to 3 litres/hectare use no more than 2 litres/hectare. The safest product
and lower dose rate appropriate for the treatment should be used at all times.
To prepare the spray mix with water miscible products select the dose rate of product
to be applied per hectare (from the product label) and mix in a suitable container.
Examples of mixing spray - for 1 hectare (for 2,000m² i.e. 0.1ha, divide quantities by
10):

CALIBRATION
The workrate when using the ELECTRAFAN 12 will be dependent on the particular
situation. In glasshouses/polytunnels it will depend on the type of crop being treated
and the row spacing. In crops such as vegetables and flowers it will generally take
around 45 minutes to spray an area of 1,000m² (1/10 of a hectare). It will often be
necessary to spray crops from both sides of the row to ensure adequate penetration
and even coverage e.g. when foliage is dense, when the crop height exceeds 0.75m or
when planting beds are over 2m wide. The objective is to apply an even spray cover
to all target surfaces so it is very important for the operator to carefully direct the
spray at all areas to be treated e.g. if spraying a crop the ELECTRAFAN 12 should
be moved gently up and down along the height of the crop (with the machine held to
the side and slightly behind the operator’s direction of travel). Practice spraying -
without any spray mix in the bottle - to see what sort of walking speed is practical.
The table below indictes the relationship between spray volume, flow rate and
walking speed for the ELECTRAFAN 12 as per the following formulae:
a) Formula for calculating required flow rate:-
Flow rate = 6 x spray pass interval x total spray volume x walking speed
(ml/min) (m) (l/ha) (m/s)
b) Formula to calculate the volume applied from a known flow rate:-
Measured flow rate (ml/min) x 10 = spray volume (l/ha)
Area sprayed in one minute (m²)
The following table is a guide to liquid flow rates through various feed nozzles:
Feed nozzle Flow rate (ml/min)
(orifice diameter marked
in mm on nozzle)
Water Oil (7mm²/sec viscosity)
0.9 23 18
1.1 (fitted) 55 40
1.3 63 46
1.4 85 50
1.6 105 56
2.0 N/A 77
N.B. Liquid flow rates should always be measured with the actual spray mix.
Do not use flow rates over 110 ml/min.
8
To check the flow rate wear the appropriate protective clothing. Choose and fit the
feed nozzle that is likely to be required (see ‘TO CLEAN FEED NOZZLE’ for fitting
instructions). Fill the bottle with the spray mix, attach to the sprayer (avoiding spill-
age) and then turn the sprayer over above a suitable container (N.B. do not switch on
the sprayer). Wait until the liquid flow is steady and then allow the liquid to flow
into a measuring container for one minute and measure the volume dispensed. If the
flow rate is very different from that required change the feed nozzle and repeat the
above procedure. If the flow rate is close to that required adjust walking speed.
Example: Required spray volume = 30 l/ha; Spray pass interval = 2m
Flow rate measured = 85 ml/min
Walking speed (m/s) = Flow rate (ml/min)
6 x spray pass interval (m) x total spray volume (l/ha)
= 85 = 0.24 m/sec
6 x 2 x 30
i.e. 0.24 m/s or 14.4 m in one minute (0.24 x 60)
Mark out a distance of 14.4 m and practice walking it in one minute using the sprayer
as during the operation (see ‘BEFORE SPRAYING’).
