STAUFF has been manufacturing high-quality replacement elements for filters for more than 20 years. These replacement elements "made in Germany" are intended for filtering hydraulic oils, lubricants, cooling lubricants, fuel, chemical cleaning agents and water and fit into the housings of all the standard makes on the market. The design of the plastic cartridge for filtering lubricants in the Boll & Kirch automatic filter series (housing 6.46) has recently been improved and optimized.
