Housing and dimensions
The welded housing is made of stainless steel 1.4404, or 1.4301 on request, with flanges according to EN 1092-1/11 PN16 (ANSI B16.5 WN Class 150 on request) and FKM seals. 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 |
|---|---|---|---|
| Flow (l/min) | 181,440 | 288,000 | 397,440 |
Element and accessories
Where to place it
It goes after the sintered pre-filter or the dust filter, before the WFIFS microfilter: it protects the microfilter element, which then lasts longer.
You will find other sizes among the filters of the same stage.
