Description
- Z-line filter type ZLW for the separation of coarse dust in ventilation and air conditioning systems
- Coarse dust filter: Prefilter in ventilation systems
Special features
- High dust holding capacity at low initial differential pressure
- Long filter life
- Quick fitting and removal
- Low weight and small transport volume
- Can be easily and safely disposed of in municipal refuse incineration plants as emissions are low in harmful substances
Nominal sizes
- B × H × T [mm]
Filter group
- ISO Coarse to ISO 16890
Filter classes
- Coarse 90 %
- Coarse 60 %
Construction
- PLA: Frame made of plastic

- Available in various filter classes and sizes, including commercial installation depths and cross-sections
Materials and surfaces
- Filter media made of synthetic fibers
- Cardboard frame
- Optional frame made of plastic, galvanized sheet steel, stainless steel or aluminum
- Optionally with flat profile seal on the upstream or downstream side or on both sides
Standards and guidelines
- Test according to ISO 16890; international standard for general ventilation and air conditioning; classification of efficiency based on the measured fractional efficiency, which is processed into a reporting system for the fine dust efficiency (ePM)
- For coarse dust filters, the gravimetric separation is measured with synthetic dust
- The filters are classified into filter group ISO Coarse depending on the tested values
- 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, ISO ePM2.5 and ISO ePM1 depending on the tested values
