4. Rotary dusters Rotary duster

5. Knapsack Duster

6. Power Operated Duster

7. Plunger Duster

8. Bellow Duster

9. SPRAYERS Principle : Atomize spray fluid into droplets Important parts: Tank – built in/separate - 9 – 13 lit Pump – MOST VITAL PART - create energy – atomization Air pump (pneumatic) Positive displacement pumps Agitator Pressure gauge Valves – govern direction of spray fluid

10. Contd., 6. Filter – b/w tank and pump; b/w pump and spray lance; within lance - prevent blocking of nozzle 7. Pressure chamber - effect uniform spraying 8. Hose
