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.
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. Specification of Air Atomizing Spray Nozzles External Mixture:
