AIR CRAFT SPRAYER

Air craft spraying is meant for larger farms. Areal spraying is affected by wind. Atomising devices use one or more of the following principles to break the liquid into droplets.

• Pressure or hydraulic atomization, which depends on liquid pressure to supply the atomizing energy.
• Pneumatic or gas atomisation in which the liquid is broken up by a high velocity air stream.
• Centrifugal atomisation in which the liquid is fed under low pressure at the centre of a high speed rotating disc or cup. The liquid is broken up by centrifugal force as the liquid leave the periphery of the disc or cup.
