We have two types of atomizers, namely voltage net atomizer and compression atomizer. The product characteristics of voltage grid atomizer are as follows: first, the median particle size of fog particles is MMADuM ±25%; secondly, quiet atomization with low decibels; finally, the proportion of fog particles with equivalent volume particle size distribution diameter of 1um~5um is more than 50%. Compression atomizer adopts high efficiency oil-free compression pump, wear resistance, high temperature resistance and stability, special atomization cup with low operating noise, ultra-fine atomized particles, average about 3um.
