The new type of low-pressure filter is widely used in various fields such as hydraulic, lubrication, water treatment, chemical, and food due to its high efficiency, low pressure drop, strong durability, and intelligence. When selecting, it is necessary to choose the appropriate model and material based on specific operating conditions (such as flow rate, pressure, medium characteristics) and filtration accuracy requirements. In addition, regular maintenance and replacement of filter cartridges are key to ensuring the long-term stable operation of the filter.
