ST2000 is a scent diffuser machine which adopt steel material and column design. The spray nozzle is inclined upwards, which makes the speed of scent faster and the effect is more even. The operation panel is hidden at the back, which can avoid being arbitrarily changed by others to the selected settings. It is very suitable to be placed in public consumption places, and can be perfectly integrated with the surrounding environment. It is not so much a machine as it is a work of art.
