The central water Pre-filter is mainly used to ‘capture’ the particulate impurities, sediment, rust, floating particles, and other big size pollutants in the water. It is like a ‘primary wall’ to protect your house appliances and plays a positive role in protecting & extending the terminal water production equipment service lifetime, such as downstream pipes, water purifiers, water heaters,wall-mounted furnaces, washing machines, bathroom showers and so on. The prefilter is flushable and reusable.


NFT-SMD-MK002 is our Basic Double Scraping product in Brass head design. As an upgraded type, the new generation SMD series also the same with other types of Pre-filter, simply to be installed and indicates when the mesh filter needs cleaning through the housing body. However, not only the sturdy plastic scraping frame clings to the stainless steel mesh and can effectively scrape off impurities by gently twisting, but also silicone scraping strip makes the clean process much more efficient. Some types with different configurations of pressure gauge, pressure control valve, and rotatable head which can effectively adapt to various filtration requirements.

The protection cover (color, position, logo, etc) and configurations can be modified to meet your needs.
