A 0.3 nozzle or 0.4 nozzle means that the nozzle has a spray hole diameter of 0.3mm or 0.4mm. The nozzle with this spray hole diameter is generally an atomizing nozzle. The principle is that the water pump pressurizes the liquid and forms a regular pattern in the nozzle cavity after entering the nozzle. The rotation is then sprayed out from a spray hole with a diameter of 0.3mm or 0.4mm, spreading into a mist state.

From a visual point of view, the spray state of the two nozzles is not much different, but if you use precision instruments to measure, the result is that the 0.4mm diameter nozzle has a larger jet flow rate than the 0.3mm diameter nozzle, and the diffusion angle and the number of atomized particles are also larger. Some. However, the average particle size of the droplets sprayed by a nozzle with a diameter of 0.4mm must be larger than that of a nozzle with a diameter of 0.3mm. Therefore, when choosing a nozzle, you should decide according to your actual use.
