Hydraulic Filtration
Duplex Filters / Inline Filters, Switchable
For the separation of solids and pressure fluids and lubricating oils.
Duplex filters are used in hydraulic systems for separating solid materials from the hydraulic fluids and lubricating oils. They are intended for installation into piping. The filter element can be changed without any operational interruption.
