  • Description
Application

  • Pocket filter made of NanoWave® medium type PFN for the separation of fine dust
  • Fine dust filter: Prefilter or final filter in ventilation systems

 
Nominal sizes
  • B × H × T [mm]
Construction features

  • Wedge-shaped filter pockets
  • Multi-layer filter medium with a prefilter layer and a layer of corrugated extra fine fibres
  • Frame depth of construction PLA: 25 mm
  • Frame depth of construction GAL: 20, 25 mm
  • Number of pockets: 3, 4, 5, 6, 7, 8, 10


Materials and surfaces

  • Filter media made of synthetic fibres in corrugated structure
  • Frame made of plastic or galvanised sheet steel


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)
  • The filters are classified into filter groups ISO ePM10 and ISO ePM1 depending on the tested values
  • Construction PLA meets the hygiene requirements of VDI 6022, VDI 3803, DIN 1946 Part 4, ÖNORM H 6021 and ÖNORM H 6020, SWKI VA 104-01 and SWKI 99-3, and EN 16798

Pocket filter PFN made of NanoWave® medium as prefilters or final filters for the separation of fine dust in ventilation 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.
