20 micron string insert for 9 inch tubular water filter

20 micron replacement string insert designed for pipe filter with a diameter of 9. The offered cartridge is dedicated to the watering line. It effectively cleans water of mechanical impurities, i.e. sand, silt, rust, coal dust and others. The fibers from which the filter layer is made during water treatment do not cause large pressure drops.

The string insert is made of the highest quality polypropylene fibers wound on the filter core. With the increase in the amount of retained impurities, the cartridge changes color, e.g. to dark yellow or brown, which depends on the type of water impurities. The cartridge is characterized by a long service life.
