Type ZL

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 classes G4 (coarse dust filter), M5 (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 or plastic
Tested to EN 779

Application

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

Special characteristics

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

Filter classes

Coarse dust filters G4
Fine dust filters M5

Construction

NWO: Frame made of non-woven fibres
PLA: Frame made of plastic

Useful additions

Standard cell frame (SCF-B)

Construction features

Folded filter media
Moisture-resistant, rigid filter frame
Available in various filter classes and sizes, including commercial installation depths and cross-sections

Materials and surfaces

Filter media made of synthetic fibres
Frame made of non-woven fibres or plastic

Technical information

Z-line filters type ZL for the separation of coarse dust when used as a prefilter, and for the separation of fine dust when used as a prefilter or final filter in ventilation systems.

Available in various filter classes and sizes, including common installation depths and cross-sections, filter classes G4, M5.

Filter media is folded; this increases the dust holding capacity and extends the filter life.

Special characteristics

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

Materials and surfaces
