Double filter box

Available in filter class M6 - F8 according to EN 779

Our German air filters have a maximum surface in little space and therefore a long service life under economic operating conditions. By means of the proven minipleat technology with hot-melt fixation of the folds, optimal use of the same surface and maximum stability can be guaranteed at the same time. High-quality, wet-laid fiberglass is used for these filter media.

This double filter box has a double top frame on 2 sides. The dimensions are 592 x 592 x 292 mm.
