Spool cartridge filters

Spool cartridge filters are generally made of polypropylene soldered onto a base made of the same material.

For filters that must offer chemical resistance, the cartridges are built on a base of stainless steel, onto which the cotton or glass fibres are wound. In this type of cartridge, the liquid moves from the exterior to the interior. They are relatively inexpensive but their impurity retention capacity is relatively low, meaning the cartridges must be replaced more frequently. It is also possible that pollution is released in case of excessive pressure drop.
