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.
For oil separation, the air flows through the coalescing element from the inside out, and the filter is mounted head up with the bowl down.
Dimensions according to the manufacturer: height A 1,496 mm, length across the flanges B 660 mm, housing diameter C 406.4 mm. Weight 201 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 |
|---|---|---|---|
| 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 PFS microfilter: it protects the microfilter element, which then lasts longer.
You will find other sizes among the filters of the same stage.
