Product detailed description
The PFIW1-094 welded process pre-filter traps solid particles larger than 1 µm. It has a G 2" connection (female pipe thread), a flow of 15,000 l/min at 7 bar and a working pressure of up to 14 bar.
It belongs to the PF process filters, among the PFIW1 welded pre-filters: the housing is the same for all stages, only the element differs.

Housing and dimensions

The housing is made of stainless steel 1.4404, or 1.4301 on request, with the outer surface polished to Ra 1.6 and EPDM seals (FKM or silicone on request). It withstands −20 to +150 °C; the actual limit depends on the seals and the element.
According to the manufacturer: height A 445 mm, width across the connections B 180 mm, housing diameter C 114.3 mm. Weight 5.2 kg.
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) | 9,450 | 15,000 | 20,700 | 28,200 |

Where to place it

It goes after the basic mesh, before the PFM fine pre-filter — instead of the PFI1 sintered pre-filter.
You will find other sizes among the filters of the same stage.
