BFHPS flanged microfilters up to 25 bar
BFHPS flanged microfilters up to 25 bar trap the finest particles larger than 0.01 µm and oil; residual oil is below 0.01 mg/m³. They belong to the range of Omega Air BFHP flanged filters up to 25 bar: the welded carbon steel housing is the same for all stages, and the element determines the stage.
10 sizes with DN80 to DN300 flanges, flow of 1,680 to 31,400 Nm³/h at 7 bar and 1 to 20 elements. Working pressure up to 25 bar, temperature +1.5 to +65 °C. Supplied as a filter housing with elements, without a condensate drain.

When to use it
The microfilter suits applications where the air must be clean of solid particles and oil to class 1-x-1 according to ISO 8573-1.
The fine pre-filter M, which traps particles down to 0.1 µm, goes before the microfilter. The microfilter is also the mandatory stage before activated carbon A — only with it does solid particle class 1 apply.
Where to place it
After the BFHPM fine pre-filter, before the BFHPA activated carbon filter. The 0.01 µm microfilter traps the finest particles; the coarser ones must be trapped by the stages before it.
Element, replacement and drain
Element BFS-0240V: borosilicate microfibres, pressure drop of a new element 80 mbar. Replace the elements once a year, or earlier when the pressure drop reaches 350 mbar. The pressure drop is shown by the MDHI 50 differential pressure gauge.
The condensate drain is ordered separately — for this range, the manufacturer lists the TD 50M timed drain and the AOK 50B float drain. Elements for all stages are among the BFHP spare elements.
Flow at a different pressure
The flows in the tables apply to a pressure of 7 bar and a temperature of +20 °C. At a different pressure, multiply the flow by the manufacturer’s correction factor:
| Pressure (bar) | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 12 | 14 | 15 | 18 | 20 | 22 | 25 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Correction factor | 0.38 | 0.5 | 0.63 | 0.75 | 0.88 | 1 | 1.13 | 1.25 | 1.38 | 1.63 | 1.88 | 2 | 2.37 | 2.63 | 2.89 | 3.25 |
For other conditions, such as a different temperature, the flow has to be recalculated — contact us.
