Hand atomizer

• This sprayer has a container of 0.5 to 3.5 liters capacity.
• The container has inside a built-in pump.
• The outer end of the pipe terminates in a nozzle with 0.6 – 1.6 mm diameter orifice.
• The container is filled to approximately three fourth of its capacity and air is compressed on the remaining space by means of the pump.
• Before use, the plunger type pump is worked to develop an air pressure of 0.15 – 0.35 kg/cm2.
• The spray comes out from the nozzle usually via. a suitable trigger control valve.
• The application rate ranges from 18 to 45 liters per acre.

Hand compression sprayer

• Suited for spraying large quantities of liquids.
• comprises a tank for holding spray material and compressed air, vertical air pump with a handle, filling port, spray lance with nozzle and release and shut-off devices.
• As the spraying proceeds, the pumping is required to maintain the normal pressure of 2.0 – 3.5 kg/cm2.

Knapsack hand compression sprayer

• Capacity of tank is 10-20 liters.
• It is generally, made of galvanized, iron, brass or stainless steel.
• provided with a built-in double barrel spray pump of piston or diaphragm type with a lever for operating.

Rocker sprayer

• consists of pump assembly, platform with frame and fork, operating lever, pressure chamber, suction hose with strainer, delivery hose, extension rod with spray nozzles, etc.
• The rocking movement of the handle helps in building pressure in the pressure chamber.
• There is no built-in tank and separate spray tank is necessary.
• The sprayer builds up a high pressure of 14-18 kg/cm2.

Foot or pedal sprayer

• consist of plunger assembly, stand, suction hose, delivery hose, extension rod with a spray nozzle etc.
• One end of the suction hose is fitted with strainer and the other with a flexible coupling.
• Similarly, the delivery hose has one end fitted with a sheet off pistol and the other with a flexible coupling.
