Housing and dimensions

The welded housing for pressures up to 50 bar is made of stainless steel 1.4404, or 1.4301 on request, with FKM seals (EPDM or silicone on request) and female pipe threads. 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 50 bar it is 6.38:
| Pressure (bar) | 7 | 16 | 30 | 50 |
|---|---|---|---|---|
| Flow (l/min) | 15,000 | 31,950 | 58,200 | 95,700 |
Element and accessories
| For this filter: | |
|---|---|
| Spare element | PFIW1-094V |
| Condensate drain (ordered separately) | AOK50SS, TD420M-230VAC |
| Differential pressure gauge for the filter head | MDHI50-K |
Where to place it

It goes after the basic mesh or the fibre pre-filter, before the WHFITM fine pre-filter — instead of the WHFITI1 sintered pre-filter.
You will find other sizes among the filters of the same stage.
