It consists of two plastic tanks (fuel and water/dust), engine, pump,
spray hose, rope starter, delivery pipe, cut-off-cock, shoulder straps
and a frame. It has a small 2-stroke petrol/kerosene engine of 35 cc
to which a centrifugal fan is connected. The fan produces a high
velocity air stream, which is diverted through a 90-degree elbow to a
flexible (plastic) discharge hose, which has a divergent outlet. Upon
rotation of the engine the fan produces a high velocity air stream.
The control valve for the spray is opened gradually and adjusted for
the desired flow rate. The operator directs the discharge hose to the
target. It can be converted for dusting and ULV application.
