7.2 POWER KNAPSACK SPRAYER

 

Features:

 

It consists of a frame on which fuel tank, engine and hose with cut-off mechanism are mounted. The frame is provided with shock-proof cushion that comfortably fits on the back of the operator to reduce transfer of vibrations to the operator. The 1-3 hp engine has electronic ignition, which is easy to be operated and maintained. It is provided with an on-off control switch and a mechanism for adjusting the discharge rate from 0.5-5.0 litre/min. The spray liquid is blown-out by an air current generated in the tank. The liquid from the tank passes through a tube to the nozzle on the spray lance by gravity. It has provision for dusting and ULV application.
