PFSF stainless steel filters with a sterile element up to 14 bar

The PFSF sterile filter is the last filtration stage of the PF range. It has a sterile element with a filtration rating of 0.01 µm and a polished stainless steel 1.4404 housing.
The PFSF filter comes in 18 sizes (G 1/4" to DN200) with flows of 1,250 to 352,000 l/min at 7 bar; working pressure up to 14 bar, sizes from DN100 up to 10 bar. It is one of the stages of the PF filters — the housing is the same for all stages, only the element differs.
PFSF filters by size
The size determines the connection and the flow. Each size has its own PF range spare element.

When to use it
The sterile filter goes at the end of the filtration, after the fine pre-filter and the microfilter. The manufacturer designs the PF range for pharmaceuticals, biotechnology, the food industry and hospitals, among other uses.
Where to place it

At the end of the filtration, after the PFM fine pre-filter, the PFS microfilter and the PFA activated carbon.
Flow by pressure
The catalogue 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.

Element, condensate drainage and maintenance

A PF range element is fitted in the housing — for example, the PFSF-010V for the PFSF-010. The same element also fits the HPFSF-010. Flanged filters from DN100 have several elements — their number is given in the table for each size. Element working temperature −20 to +150 °C.
The filter is supplied with an element, without a condensate drain. 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.
Replace the element at least once every 12 months. Once a year, also check the housing for visible damage.
Accessories for PFSF filters
The same stage in other ranges
Stage SF also comes in the HPFSF filters up to 50 bar. The elements are the same for all ranges.
Ventilek’s tip
The sterile element goes last. Stages that trap solid particles and oil go before the sterile filter. The sterile element is then the final safeguard of air purity.
- What filtration rating does the PFSF sterile element have?
- 0.01 µm.
- Where should it be placed?
- At the end of the filtration, after the fine pre-filter and the microfilter.
- When should the element be replaced?
- At least once every 12 months.
