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 filter PFN made of NanoWave® medium as prefilters or final filters for the separation of fine dust in ventilation and air conditioning systems. Wedge-shaped filter pockets ensure ideal airflow conditions. Highest possible dust holding capacity with an extremely low initial differential pressure due to a multi-layer filter medium with a prefilter layer and a layer of corrugated extra fine fibres. Pocket filters made of NanoWave® medium are available in standard sizes with variable numbers of pockets and pocket depth, filter groups ePM10 and ePM1 according to ISO 16890. Pocket filters made of NanoWave® medium are Eurovent-certified and compliant with VDI 6022 in terms of hygiene. The PFN-EX pocket filters with optional EX protection may be used in areas with a potentially explosive atmosphere of zones 1 and 2, as well as zones 21 and 22 (EX II 2G Ex h IIC Gb and EX II 2D Ex h IIIB Db). It is mandatory to connect the filters to the earth potential. All conductive and dissipative parts must be connected together and grounded. Conductive dusts are excluded from the application. Under no circumstances should metallic foreign materials enter the filter.
