For high dust concentrations or as a prefilter for fine dust filters

Z-line filters for the separation of coarse and fine dust, used as the first stage in ventilation and air handling units or as prefilters for high-quality filter stages

Filter groups ISO Coarse (coarse dust filter) and ePM10 (fine dust filter)
Large filter area due to folding
Low differential pressures at high volume flow rates
Moisture-resistant, frame made of non-woven fibres
Optional frame made of plastic, galvanized steel, aluminum
Tested to ISO 16890

Category: Filter Media Tag: ZL

General Information

Application

Z-line filter for the separation of coarse and fine dust in ventilation and air conditioning systems
Coarse dust filter: Prefilter in ventilation systems
Fine dust filter: Prefilter or final filter 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

Standards and guidelines

Test according to ISO 16890; international standard for general ventilation and air conditioning; 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 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

Specification Text

Z-line filters type ZL for the separation of coarse dust when used as prefilters, and for the separation of fine dust when used as prefilters or final filters in ventilation systems. Available in various filter classes and sizes, including common installation depths and cross-sections, filter groups ISO Coarse and ISO ePM10 according to ISO 16890. Filter media is folded; this increases the dust holding capacity and extends the filter life.

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
