Product detailed description
The WFIWIW20-030 welded process pre-filter traps solid contaminants larger than 20 µm and protects the finer stages after it. It has welding ends for a ø 33.7 mm pipe, a flow of 5,250 l/min at 7 bar and a working pressure of up to 14 bar.
It belongs to the WFIW process filters, among the WFIWIW20 welded pre-filters: the housing is the same for all stages, only the element differs.

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) | 3,308 | 5,250 | 7,245 | 9,870 |
Element and accessories
| For this filter: | |
|---|---|
| Spare element | PFIW20-030V |
| Condensate drain (ordered separately) | AOK20SS |
| Differential pressure gauge for the filter head | MDHI50-K |
Where to place it
It goes at the start of the filtration or after the WFIWN25 coarse filter, before the WFIWN5 basic filter — instead of the WFIWI20 sintered pre-filter.
You will find other sizes among the filters of the same stage.
