This document introduces the HD-Feinfilter Typ W11 - W12 product from Hochdruck - Reduziertechnik GmbH. This product is designed to protect their high pressure pressure regulators of the series J, K50 and D from metal abrasion and other dirt particles. The filter should be installed as close as possible to the pressure regulator. If fine filters are not present in the system, it is recommended to pre-install this filter, as the accuracy and service life of the reducing valves are typically significantly increased by a clean medium.
