Pufen has kept developing the atomization technology since the establishment of the company. After six years of continuous experimentation and exploration, the new generation of fragrance equipment has smaller atomized particles (diameter≤10μm ). The sizes of atomized droplets are more uniform (the uniformity index N is usually higher than 2 while the average ultrasonic N index is between 1.1-1.7; N is the index of the R-R distribution function). The upgraded fragrance equipment has a better atomizing effect and more uniform diffusion. The straight-line height of atomization air column can reach 50cm, which means the spray of the atomization column can be clearly felt under the natural light. The atomizing nozzle will not spout oil or particles; it can be used for long-time atomization and will not have oil accumulation. There will be no solidification or clogging at the nozzle position.
