75 um 250 mm string wound filter cartridge

A 75 um 250 mm string wound filter cartridge is a type of filter cartridge used for water filtration. The 75 um refers to the size of the particles that the filter can capture, with a smaller number indicating a finer filtration level. The 250 mm size refers to the length of the filter cartridge. String wound filter cartridges are made by winding string around a core, creating a dense filtration layer that can effectively capture sediment, dirt, and other particles from water. These cartridges are commonly used in industrial and commercial water filtration systems.
