The LS-12 foam generator (with external syringe) is a high-performance cleaning accessory that is widely used for cleaning cars, trucks and other mechanical equipment. It uses the powerful power of high-pressure water flow to suck the detergent from the barrel through the siphon principle and mix it with the water flow to form a cleaning solution. The mixed liquid is sprayed out through the foam generator to produce fine and rich foam, which evenly covers the surface of the object, effectively dissolving oil stains and stubborn dirt, thereby improving the cleaning effect. The LS-12 is simple and practical in design. It can achieve efficient cleaning functions by simply working with a high-pressure cleaner without the need for additional equipment support. The external syringe pipette is directly inserted into the barrel, making the use of detergent more convenient and eliminating the trouble of frequently changing small bottles. It is especially suitable for fixed car wash locations for long-term use.
