Screen Filter
The screen filter is highly effective for removing inorganic impurities from water. As water flows through the mesh, particles larger than the mesh aperture are intercepted. As impurities accumulate on the mesh surface, the pressure differential across the filter increases. If the pressure difference becomes too large, the mesh pores may expand under pressure, allowing impurities to pass through into the irrigation system and potentially causing mesh damage. Therefore, proper management measures must be taken to ensure that the pressure differential remains within the allowable range. Only with appropriate model selection and operation under normal conditions can the screen filter function efficiently and economically. During filtration, impurities are trapped on the inner side of the mesh. When flushing is needed, the drain valve on the flushing port is opened, and the high-speed water flow quickly expels the retained impurities from the filter. The screen filter uses scientifically distributed mesh pores to retain sand, suspended solids, and other impurities from raw water, delivering excellent retention performance and significantly improving the quality of the filtered water.

Precautions
1. When a certain amount of debris accumulates on the filter screen, the pressure drop between the inlet and outlet will increase significantly. If the pressure drop exceeds 0.07 MPa, cleaning must be carried out promptly.
2. The flow direction must follow the specified direction of the filter element. Reverse flow is strictly prohibited.
3. If the filter element or sealing ring is found damaged, it must be replaced immediately; otherwise, the filtration effectiveness will be compromised.
4. During winter or periods of non-use, the water should be completely drained to prevent freezing damage.
