The anti-drip fine atomizing nozzle uses a brass body with an inlaid stainless steel nozzle core and stainless steel guide vanes. It contains an anti-leakage device. Under water pressure of 0-120kg, the liquid flows at high speed, forming a centrifugal vortex in the guide vanes, and is sprayed out from the nozzle hole as extremely fine hollow mist particles. Using a special ferrotan mesh, the mist particle size is about 50 μm. It is widely used in factory humidification, salt spray tests, artificial fog and other humidification applications. The nozzle hole is drilled using an American precision drilling machine, with a hole diameter between 0.1mm and 15mm. It is well-made and its operating cost is more than 10 times lower than that of gas humidification.
