External mix Air atomizing nozzle with Pressure Flat Spray Pattern
Air and liquid streams are mixed separately from the nozzle outlet outside the nozzle.
Because there is no connection between the air and liquid lines inside the nozzle, the air and liquid flows can be controlled independently, allowing precise measurements of the liquid.
The atomization effect can be controlled by adjusting the air flow. The greater the air flow, the better the atomization effect.
External mixing units can be used for liquids with viscosity.
All external mixing air atomizing nozzles can work in viscosity above 250cp, external mixing nozzle flow rate is the highest, air and liquid flow can be adjusted independently.

Design Features

• Two fluid feed design, air and liquid mix outside the nozzle
• Air and liquid flow rates can be controlled independently
• External mix structure allowing precise metering of the liquid
• Suitable for atomizing of viscous liquid

Spray flow is adjustable

The nozzle has the function of adjusting the spray flow rate.So how does the air atomizing nozzle adjust the flow size?
1. Different flow rates can be obtained by adjusting the gas-liquid pressure ratio.
2, air atomizing nozzle with adjusting needle valve, manual knob can adjust the needle valve to adjust the size of spray volume and spray shape.

Common Applications

External mixing fan air atomizing nozzle is widely used in flue gas evaporative cooling, air humidification, chemical treatment, chemical agent spraying, liquid spraying, component cooling, wetting and rust removal, tobacco humidification, tablet coating, sterilization and disinfection, fruit wax spraying, ceramic tile glaze and other fields.
