The LS-12 foam generator is a professional cleaning equipment accessory that is widely used in car cleaning, truck cleaning, and cleaning and maintenance of various mechanical equipment. It uses the powerful water flow generated by the high-pressure cleaner, combined with the siphon principle, to draw detergent from the detergent barrel through the built-in syringe, and mix it with the water flow to generate a cleaning liquid. This liquid is converted into rich and delicate foam through the foam generator, and evenly sprayed onto the surface to be cleaned, quickly reacting with dirt such as oil and dust, effectively removing attachments and improving the cleaning effect. The design of the LS-12 foam generator is simple and easy to use. Cleaning work can be completed using a high-pressure cleaner without the need for additional equipment. The suction tube with a built-in syringe is directly inserted into the large barrel of detergent, avoiding the trouble of frequent detergent changes in traditional methods. It is particularly suitable for high-frequency use places such as car washes.
