EVERZIT® P

Petroleum-coke filter media in accordance with DVGW W 213

EVERZIT® P is a filter media made from calcined carbon. It has outstanding abrasion resistance and a porous surface.

EVERZIT® P is made up of more than 98 % carbon and is therefore virtually inert. It leaches out practically no silicic acid or other substances into the filtered water.
