Pocket Filters G3 - G4

EMW® coarse dust filters are primarily used in turbomachinery air intake systems, ventilation and air conditioning systems, laboratories, chemical and pharmaceutical plants as well as in fume removal hoods at workplaces.

These pocket filters - available in stitched and welded versions - are made of synthetic media fulfilling Filter Classes G3 - G4. (Pocket filters in filter classes M5-F9 can be found under medium and fine dust pocket filters)

EMW® coarse dust filters are available with plastic or metal frames. If required by the intended application, the prefilter can be equipped with a continuous foamed-in-place seal as an additional option.

These products are available in a variety of standard sizes. Special sizes are available as well on request.

All data given are based on test results determined according to EN 779 or ISO 16890. 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 according EN 779 is measured till a final pressure drop of 250 Pa, whereas according ISO 16890 the dust holding capacity is measured till 200 Pa. If higher final pressure drop levels are suitable, the dust holding capacity will be accordingly higher.
