PEM Fuel Cell Flat Material Ultrasonic Conical Spray Nozzle

PEM Fuel Cell Flat Material Ultrasonic Conical Spray Nozzle

Description: 

PEM Fuel Cell Flat Material Ultrasonic Conical Spray Nozzle adopts an air cover, which can form a wide "vortex like" dispersion, making it very suitable for coating flat objects such as PEM fuel cells and solar cells. It is best to use a reciprocating vortex type nozzle. You can use a simple XY workbench.
PEM Fuel Cell Flat Material Ultrasonic Conical Spray Nozzle produces a medium width spray pattern, which is wider than the gathering type ultrasonic nozzle, but narrower than the spray pattern of the wide type ultrasonic nozzle. The vortex type ultrasonic nozzle uses low-speed rotating air/gas to produce a wide and stable spray pattern. The vortex type ultrasonic nozzle produces a conical spray pattern with a diameter of 2 – 4 inches (50 – 100 mm), depending on the distance from the substrate. The vortex velocity can vary depending on the application.
