PF stainless steel process filters up to 14 bar, G 1/4" to DN200
PF process filters from the manufacturer Omega Air have a housing made of stainless steel 1.4404 with the outer surface polished to Ra 1.6 and EPDM seals. They work up to 14 bar; the large flanged sizes from DN100 up to 10 bar.
Six filtration stages range from a 25 µm stainless steel mesh to a 0.01 µm microfilter. The range has 18 sizes with G 1/4" to G 3" threads and DN100 to DN200 flanges, with flows of 1,250 to 352,000 l/min at 7 bar. It is one of the stainless steel process filters.

The manufacturer does not state a class for the stainless steel meshes and sintered elements. The temperature is the limit of the element; the housing withstands +150 °C.

How to put the filtration together
The stages are arranged from coarse to fine in the direction of flow. Each stage protects the finer stages after it, so their elements last longer.
The welded pre-filter IW1 is a different design of the 1 µm stage — it is used instead of the sintered pre-filter I1. The fine pre-filter M goes before the microfilter S and protects its element.
Sizes and dimensions
The size determines the connection, the flow and the housing dimensions. All stages of the same size have the same housing; only the element differs. Sizes 005 to 240 have one element and a thread; sizes 450 to 2000 have a flange and 3 to 10 elements.
Height A is 206 to 1,496 mm, the weight 1.8 to 202 kg.

Flow at a different pressure
The flows apply to a pressure of 7 bar and a temperature of +20 °C. At a different pressure, they are multiplied by the correction factor: 1.88 at 14 bar, 0.63 at 4 bar.

Housing and connection
Housing: stainless steel 1.4404, 1.4301 on request, EPDM seals (FKM or silicone on request), outer surface polished to Ra 1.6. It withstands temperatures from −20 to +150 °C; the actual limit depends on the seals and the element.
For oil separation, a coalescing element (fine pre-filter M or microfilter S) is fitted in the housing; the air flows through it from the inside out, and the filter is mounted head up with the bowl down.
The filter is supplied with an element, without a condensate drain.
Accessories
Condensate drainage
For PF filters, the manufacturer offers the AOK20SS stainless steel float drain up to 20 bar and +65 °C. The drain outlet in the bottom has a G 1/4" thread, G 1" for the flanged sizes.
Other ranges
Other process filters: HPF filters (50 bar), WFIT filters (14 bar) and WFIF filters (14 bar, DN100 10 bar).
Ventilek’s tip
For oil, mount it head up. The fine pre-filter M and the microfilter S only separate oil when the air flows through them from the inside out and the filter hangs head up with the bowl down.
- What pressure are PF filters rated for?
- Up to 14 bar; flanged sizes from DN100 up to 10 bar. The housing withstands −20 to +150 °C; the elements have their own temperature limit.
- What is the housing made of?
- Stainless steel 1.4404, or 1.4301 on request. The outer surface is polished to Ra 1.6; the seals are made of EPDM, or FKM or silicone on request.
- How do I choose the size?
- By the flow at your pressure. The flows apply to 7 bar; at a different pressure, multiply them by the correction factor — at 14 bar it is 1.88.
- Is a condensate drain included with the filter?
- No. The filter is supplied with an element; the condensate drain is ordered separately. The AOK20SS float drain up to 20 bar is suitable.
- How often should the elements be replaced?
- At least once every 12 months. Once a year, also check the housing for visible damage.
