The special internal structure enables the liquid and gas to be uniformly mixed to produce small droplet spray or coarse droplet size. Generally, a finer droplet spray can be obtained by increasing the gas pressure or lowering the liquid pressure, resulting in an increased gas flow rate liquid flow ratio.
