Ngokungafaniyo nemilomo yoxinzelelo, imilomo ye-ultrasonic ayinyanzeli ulwelo kwi-orifice encinci isebenzisa uxinzelelo oluphezulu ukuze ivelise isitshizi. Ulwelo lutyiswa embindini wombhobho onendawo ephumayo enkulu, ngaphandle koxinzelelo, kwaye i-atomized ngenxa yokungcangcazela kwe-ultrasonic emqaleni.

Yonke i-nozzle ye-ultrasonic isebenza kwi-frequency resonant frequency, echaza ubungakanani be-droplet ephakathi. Umzekelo, umlomo wombhobho ongama-60 kHz uvelisa ithontsi ephakathi kwiimicrons ezingama-20 (xa utshiza amanzi). Okukhona iphezulu i-frequency, incinci i-median drop size.
