The delicate foam produced by the foam nozzle can penetrate into the tiny gaps and depressions on the vehicle surface, effectively remove stains and impurities, and improve the cleaning efficiency. Compared with the traditional direct water spray cleaning, foam cleaning can reduce water consumption and waste of water resources, which conforms to the environmental protection concept of modern society. The detergent ingredients in the foam are fully diluted and dispersed, reducing the direct impact and wear on the paint, and helping to protect the gloss and integrity of the paint. Rich foam covers the vehicle surface, making the car washing process more intuitive and interesting, and improving the user's car washing experience.

In pesticide spraying, the application of foam nozzles enables pesticides to act on crop leaves with smaller droplets and higher coverage, improving the control effect, and reducing pesticide loss and environmental pollution. The foam extinguishing system uses foam nozzle to mix water and foam agent and spray them out, forming a foam layer with strong coverage, effectively isolating air and rapidly reducing the temperature of combustibles, which is an important means of extinguishing oil, chemical and other fires.
