The E11 and E12 filters are available in two versions - minipleat and Al separation. With the minipleat (thermoplastic separation) the maximum possible storage depth is 150 mm, it can also be placed in larger frame depths. In the case of Al separation, uniform air flow is ensured by aluminium separators. Filters with Al separation are usually manufactured from 150 mm to 292 mm depth.
The filter block, both for Al separation and minipleat, is cast into the filter frame with a cold cured polyurethane sealant.
Filters in metal or aluminium frames can be manufactured with a collar on one or both sides. At the customer's request, filters can be fitted with protective grilles on one or both sides.
The filters are incinerable or can be disposed of in a municipal waste landfill.
When ordering, the outside dimension of the frame including the collar shall be specified.
