Standards and guidelines
Test according to ISO 16890; international standard for general room air distribution; classification of arrestance efficiency based on the measured fractional arrestance efficiency, which is processed into a reporting system for the fine dust arrestance efficiency (ePM)
For fine dust filters, the fractional arrestance efficiency of a certain size range is determined by aerosols (DEHS and KCl)
| Fractional efficiency ePM10 [%] to ISO 16890 | 60 | 75 | – | – |
| Fractional efficiency ePM1 [%] to ISO 16890 | – | – | 60 | 80 |
| Initial differential pressure [Pa] at nominal flow rate | 75 | 95 | 110 | 185 |
| maximum final differential pressure [Pa] | 250 – 350 | 250 – 350 | 250 – 350 | 250 – 350 |
| maximum operating temperature [°C] for plastic frames | 60 | 60 | 60 | 60 |
maximum operating temperature [°C] for frames made of galvanised sheet steel | 90 | 90 | 90 | 90 |
Changing the filter/Final differential pressure
The aim is to find the optimum of the longest possible service life with energetically low differential pressure and safe hygiene. A fixed, recommended value for the final differential pressure can tempt people to insist on keeping to this value, irrespective of its usefulness and today's standards with regard to, for example, energy saving, sustainability or resource conservation. To save costs and energy, we generally recommend the use of technically high-quality filters with low initial differential pressure and a flat differential pressure curve. In addition, the preferred criterion for a filter change should be the differential pressure. For further information, please refer to the installation and maintenance instructions.
Specification text
Pocket filters PFS made of non-woven synthetic fibres as prefilters or final filters for the separation of fine dust in ventilation and air conditioning systems. Filter pockets provide a high dust holding capacity at a low initial differential pressure. Pocket filters made of non-woven synthetic fibres are available in standard and special sizes; variable number of pockets and pocket depth; filter groups ISO ePM10 and ISO ePM1 according to ISO 16890. Pocket filters made of non-woven synthetic fibres are Eurovent-certified and compliant with VDI 6022 in terms of hygiene.
