Housing and dimensions
The housing for pressures up to 50 bar 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 355 mm, width across the connections B 160 mm, housing diameter C 88.9 mm. Weight 3.9 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 50 bar it is 6.38:
| Pressure (bar) | 7 | 16 | 30 | 50 |
|---|---|---|---|---|
| Flow (l/min) | 7,000 | 14,910 | 27,160 | 44,660 |
Element and accessories
| For this filter: | |
|---|---|
| Spare element | PFM-047V |
| Condensate drain (ordered separately) | AOK50SS, TD420M-230VAC |
Where to place it
It goes after the sintered pre-filter or the dust filter, before the HPFS microfilter: it protects the microfilter element, which then lasts longer.
You will find other sizes among the filters of the same stage.
