Centrifugal Blower Units (Turbines)
General information
The blower unit is located at the back of the machine. It contains a gearbox unit, blanking plate, casing, outlet hoses and
nozzles, turbine and clutch. There are two different turbine models: the steel model assembled in P540 and P540D
centrifugal blower units, and the aluminium model assembled in HF600 blower units.

ATTENTION! The clutch is one of the most important parts in the blower unit in terms of safety. Make sure that it is in
perfect conditions (i.e. that it is not blocked, etc.). Otherwise, it could cause the blower unit to explode.
HF640D (TD3-P640 Double)
The air kit should adapt to the requirements of the booms width and crop in order to give the best application results. The
following section gives more details about the different pneumatic air kits available.
The letters HF640D means High Flow and Double, respectively. They have a polyethylene casing and turbines of 640 mm
diameter.

DANGER! UNDER NO CIRCUMSTANCES should you exceed 540 r.p.m. from the tractor PTO as there is a serious danger
of air kit explosion.

DANGER! STAY CLEAR of the air inlet and outlet while the turbine is in use. Foreign objects could be expelled fromthe
air outlet or parts of clothing could be sucked into the air inlet.
