Wound PP Micron Filters

The Wound PP Micron Cartridge Filters are one of the most popular depth filter cartridges. A continuous strand of PP is diagonally wound over a supporting perforated PP core. As the filtration takes place from the outside to the inside, the suspended particles are trapped in the depth of the maze created by the winding. The yarn itself provides for selective absorption, whilst rejecting suspended dirt particles on it its surface. This keeps the pressure drop in check and improves retention efficiency. The winding pattern and thickness of the yarn plays a role in defining the micron rating of the cartridges.
