Partial flow filter | NF 631 |
 |
 |
| Description: The partial flow filter NF is foreseen for the fine filtration of hydraulic and lubrication circuits additionally to the main filter. The big filtration area in comparison to the nominal size is the premise for a high dirt-retaining capacity even in case of small filter-fineness.
The filter NF is flanged mounted to the line.
Filter elements as fine as 5 μm(c) are available; finer filter elements on request. Element change without tools is possible. After release of the straining screw and removal of the cover the elements are accessible and could be changed. The filter elements were delivered completely inclusive seals. Cleaning of the elements not possible therefore the user should have enough spare elements on stock.
