Housing and dimensions
The welded housing is made of stainless steel 1.4404, or 1.4301 on request, with welding ends for the pipeline and FKM seals (EPDM or silicone on request). It withstands −20 to +150 °C; the actual limit depends on the seals and the element.

Flow by pressure
The flow applies to a pressure of 7 bar and a temperature of +20 °C. At a different pressure, it is multiplied by the correction factor; at 14 bar it is 1.88:
| Pressure (bar) | 4 | 7 | 10 | 14 |
|---|---|---|---|---|
| Flow (l/min) | 17,640 | 28,000 | 38,640 | 52,640 |
Element and accessories
Where to place it
It goes after the sintered pre-filter or the dust filter, before the WFIWS microfilter: it protects the microfilter element, which then lasts longer.
You will find other sizes among the filters of the same stage.
