Product detailed description
The WFITM-010 fine process pre-filter traps fine solid particles larger than 0.1 µm, water and oil aerosol; residual oil is below 0.1 mg/m³. It has a G 1/2" connection (female pipe thread), a flow of 2,500 l/min at 7 bar and a working pressure of up to 14 bar.
It belongs to the WFIT process filters, among the WFITM fine 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 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.
According to the manufacturer: height A 239 mm, width across the connections B 121 mm, housing diameter C 76.1 mm. Weight 2.2 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) | 1,575 | 2,500 | 3,450 | 4,700 |
Element and accessories
Where to place it

It goes after the WFITI1 sintered pre-filter or a mesh; it is the finest stage of the WFIT range.
You will find other sizes among the filters of the same stage.
