Filter Cartridges for Industrial Applications
As a filter cartridge manufacturer, BOHNCKE provides filter cartridges that ensure stable processes and reliable retention of fine particles. They withstand aggressive media and offer long service life. Anyone requiring consistent results relies on technology that performs layer by layer, cycle by cycle.
Filter cartridges for processes where nothing should get through
Filter candles ensure controlled flow and reliable retention of contaminants in liquid filtration. They are essential in electroplating, chemical treatment, and fine cleaning of technical media. High retention performance, compact design, and resistance to aggressive liquids make them a preferred solution when every detail matters.
