Metal mesh filter cartridges are special cartridge filters made of stainless steel. they are used when plastic filter cartridges are unsuitable, e.g. at high operating temperatures or in connection with certain chemicals as well as in proceses that take place at high pressures. They are also known as surface filters.

Activated carbon filter cartridges are equipped with steam-activated hard coal pellets and are especially designed for heavily contaminated liquids. Due to the bulk form, no blocking of the activated carbon surface by coarse dirt is possible and the period of use is extremely long. RENNER offers you an extensice range of different activated carbon filter cartridges, as well as activated carbon granulate in AK-canisters. These are used when the pure mechanical filter effect is no longer sufficient for the dissolved substances, as they are only molecular in size.
