High Pressure Filter
SF Series
 |
Technical Data STAUFF high pressure filters are designed for in-line hydraulic applications, with a maximum operating pressure of 6000 PSI (420 bar). Used together with STAUFF filter elements, a high efficiency of contaminant removal is assured. The high dirt holding capacity of the elements ensures long service life and, as a result, reduced maintenance costs. |
