String Wound Filter Cartridge

LikeFilter LFSW series string wound cartridge is a honeycomb construction depth filter cartridge. The cartridge has a loose outside and tight inner structure. The outer side traps bigger particles, while the inner side captures smaller particles. This results in the efficient filtration of the cartridge.
Polypropylene is the most commonly used material for string wound cartridges due to its broad chemical compatibility and cost-effectiveness. However, cotton, nylon, glass fiber, and polyester are available for specific applications and industries.
