In most industrial processes, fine liquid atomization is obtained utilizing air-assisted atomizers, where compressed air supplies the required energy to break the liquid and throw the droplets at a given distance from the atomizer.
An air atomizing system has, however, two inherent disadvantages:
1- The narrow inside passages require adequate filtering of air and liquid;
2- The high-speed jet will only produce narrow-angle sprays. Multiple orifice atomizers produce diverging sprays with better droplet distribution to overcome this issue.
On the other hand, the advantages are:
1- The drops they generate are the tiniest ever
2- They have various accessories to fit all applications.
