Water saving: Faucet Foamer can completely mix water and air flowing through the aerator to create a foaming effect, improve flushing power and reduce water consumption. The faucet installed with aerator can save about 40% water 7-layer filtration: Our faucet filter has 7 layers of fine filtration to ensure clean, hygienic and safe water. The 2-layer ABS perforated filter can effectively filter large particles of impurities in the water flow.5 layers of SUS 304 stainless steel filter can effectively filter small particles in the water flow. the water is too weak, restrict the water outlet when the water pressure is too high, and stabilize the water outlet when the water pressure is unstable Anti-splash and noise reduction: the perfect airflow design in the faucet jet regulator, the hollow part of the filter element is mixed with air, and the water flow is smooth, the impact is reduced , the buffered water column is uniform, and the water column is vertical to prevent water splashing Scope of delivery: 4 faucet aerator, 4 seals Quality Material: Our M24 male thread faucet perlator is made of thick chrome plated brass, SUS 304 stainless steel + ABS filter and gaskets. high quality rubber. Non-toxic, rust-resistant, wear-resistant and bright, strong and durable. Easy Installation: No tools required for assembly, so it is very easy. Just use your hands and tighten the aerator directly or use the aerator key to tighten it securely. The supplied installation key makes installation absolutely simple, even for novices. Replaceable gasket: To ensure efficient use of the ring sealing, we have prepared 2 additional sealing rings. Scope of delivery: 4 tap aerators. 4 seals. Material characteristics: Material (housing): chrome-plated brass. Material (filter): ABS + SUS304 stainless steel. Material (aerator key): chrome-plated carbon steel. Outer diameter: 24mm. Height: 12 mm. Thread: M24. When water flows from the faucet, it first passes through the 2-layer ABS plastic filter screens and enters the inner hollow of the; main element in brass. The good air circulation in the filter element allows the air and water to mix well, then pass through the 5-layer SUS 304 stainless steel filter and create enough bubbles to evacuate the ;water. The water flow is even, soft and does not splash. By adding air, the jet power of the water flow is greatly improved, which effectively reduces water consumption and saves about 40% water.
