Filters are an indispensable device on the pipeline of conveying medium, commonly installed at the inlet of pressure-reducing valves, pressure-relief valves, level control valves, and other equipment like the Fang Gong Filter. The filter consists of a cylinder, stainless steel filter mesh, drainage section, transmission device, and electrical control section. After the water to be treated passes through the filter's filter sleeve, impurities are blocked. When cleaning is needed, simply remove the detachable filter sleeve, clean it, and reinsert it. Thus, the use and maintenance are extremely convenient.
