Pocket filter for fine prefileration
Description
Rainbow Filters- pocket filters for prefiltration are optionally manufactured in plastic or metal frame. Depending on the requirement the pocket filters can be provided with an additional endless foamed sealing.
The individual pockets are available in synthetic or glass fibre media, in fine classes F5-F9, for standard same as for special dimensions.
Depending on the media and the fields of application our pockets can be supplied in ultra sonic welded or stitched version. In addition the seams are thermoplastic sealed.

*Dust holding capacity was measured according to DIN EN 779 until a final differential pressure of 450Pa. In case higher final pressures at economical operation are acceptable, dust holding capacity increases correspondingly.
**All given figures underlie test data according to DIN EN 779 or DIN EN 1822. They are mean values subject to tolerances due to the normal production fluctuation. The figures are only suitable for comparison of various types and brands, which were tested according to the same standard. Tests according to the other test standards may apparently give better values. On request comparative val according to other standards are available.
