Air Atomizing Nozzle uses air pressure and volume to produce droplets from liquid that is supplied at low pressure. The advantage of this type of system includes the ability to control droplet size independently of flow rate. Air atomizing nozzles are normally used for coating granules and other small particles. Hydraulic nozzles are capable of higher delivery capacities but typically make droplets above 100µm in diameter compared to 25µm for most air atomizing (two fluid) nozzles. Air atomizing nozzles are capable of delivering droplets in the 10 to 100µm size range, all such nozzles tend to make larger droplets at higher liquid flow rates.
