The main purpose of marine filters is to filter impurities in the fluid of ship pipelines. Marine filters are essential equipment in ship piping systems. Their main function is to filter impurities in the fluid in the pipeline, in order to protect the power system of the ship and the normal operation of various pumps. These filters, through their design and construction, can effectively filter out suspended solids, microorganisms, and large particulate impurities in seawater or freshwater, ensuring that the fluid entering the ship's power system is clean and pollution-free. The application range of marine filters is wide, including but not limited to seawater systems and freshwater systems, covering the filtration needs of seawater pumps, freshwater pumps, coolers, and other pipeline systems.
