External Mixture Flat Fan Air Atomizing Spray Nozzle

External Mixture Flat Fan Air Atomizing Spray Nozzle

External Mixture Flat Fan Air Atomizing Spray Nozzle The air and liquid streams exit the nozzle independently and are combined and mixed outside of the nozzles. Because there is no connection between the air and liquid lines within the nozzles, the air and liquid flow rates can be controlled independently, allowing precise metering of the liquid. The atomization can be controlled by adjusting the air flow rate more air produces finer atomization. In most cases these set-up do not atomize as finely as Internal Mix Setups. External Mix Set-up may be used with liquid having a viscosity.

All External mixing Air Atomizing spray nozzles can works above viscosity of 250 cP. External mix nozzles have the highest flow rates and allow the air and liquid flows to be adjusted independently. These nozzles are best where precise liquid flow is needed. we have 1/4 models and made up of SS316 material.
Other materials available are brass, SS304 and Duplex steel or based on customer requirements.

Atomizing nozzles for viscous fluids and for applications that benefit from increased spray nozzle control. i.e control of pattern and droplet size independent of shape air or atomizing air and control air.  Externally atomized with built-in pneumatic control valve.
