7.2 MOTORISED KNAPSACK MIST BLOWER CUM DUSTER

 

 

Features:

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.
