Filter Boxes

in Filter Classes M6 - H14

EMW® filter boxes provide extremely high filter surface areas ranging up to 40m². They are primarily used in turbomachinery air intake systems, ventilation and air conditioning systems, laboratories, chemical and pharmaceutical plants as well as dust removal hoods at workplaces.

Their innovative minipleat technology with hot melt pleat fixation ensures optimum utilization of filter surface and highest physical strength. The filter media used in these filter cassettes are high quality, wet-laid glass-fibre materials.

*All data given are based on test results determined according to EN 779 or EN 1822. The data are average values subject to tolerances due to normal production fluctuations. The figures are only suitable for comparison with those of other products tested according to the same standard.
**Dust holding capacity was determined according to EN 779 up to a final pressure differential of 450 Pa. Operation to higher final pressure differentials results in increased dust holding capacity.
