FIENI “AIRBLAST” FANS
HIGH PERFORMANCE “AIRBLAST” FANS
The Croplands, Cropair air-blast fans are engineered
by Fieni, a global leader in agricultural fan design,
manufacturing and innovation.
Croplands and Fieni have been collaborating since
1972, and together we set the standard for fan sprayer
performance, efficiency, penetration and coverage.
Maximum PTO Speed
Maximum PTO speed is 540 rpm.
Check the tractor PTO RPM before operating the sprayer.
More RPM at the PTO can cause damage to the sprayer
unit and can be dangerous for the operator.
Fan Pitch
All Cropair Fieni fans have multiple pitch settings and are
normally supplied in the middle position.
To maximise performance, the blade pitch can be adjusted
to match the tractor’s capability / chosen operating
parameters such as PTO rpm.
Refer to pages 12, 14 & 26
for more information of
changing pitch angles.
Fan Balance
The fan has been supplied balanced. Swapping blades
and hub components around risks upsetting the balance.
Do not operate with damaged fan blades.
If replacing a damaged blade, it’s necessary to balance
the fan.
Fan Safety Rules
Fan Guards
The sprayer unit is supplied complete with safety guards for
both incoming and outlet air. The assembled guards need
to prevent foreign bodies hitting the fan.
NEVER operate the sprayer without these guards in place.
From time to time the incoming air guard may become
clogged with leaves etc. Always disengage the fan before
removing clogged leaves etc from the guards.
The fan runs at high speed and are capable of ingesting
loose objects or clothing or ejecting objects that have been
ingested at high speed.
• DO NOT exceed maximum operating rpm
(PTO = 540 rpm)
• STAY AWAY from the fan when the tractor is running.
• DO NOT stay in the working area (air inlet or spray
outlet) of the sprayer unit.
• Always stay at a safe distance from the machine
when it is working/running.
DO NOT remove or modify the installed
protections and guards
