HEPA-filter E12 305x305x292mm Bredde

The construction of a HEPA filter consists of a very thin and dense filter material folded into a wooden or metal frame. The filter material catches particulates of dust from the air that penetrates it. High filtering ability is achieved by very low speed at which the air penetrates the filter material. Maximal speed can not exceed 0.025 m/s. To achieve sufficient air speed through the face of the filter, it is necessary to fold the filtering material into the cassette as tightly as possible, but at the same time it should be noted that the filter resistance would not become too high. In a standard filter cassette in size 610 x 610 x 292 mm has c.a. 20 m² of filter material. The most used material is glass cloth, but also different fabrics of synthetic fibre can be used.

HEPA measurements
It is possible to produce filter material in one piece with width 1220 mm, length 1830 mm and fold depth up to 280 mm.
There are different versions of the filter, which are all rustproof, easy to install and clean. We offer HEPA filters in standard sizes, with depths: 69 mm, 78 mm, 150 mm, 292 mm.

All filters have been tested according to the norms of FDA 175.105 (U.S. Food And Drug Administration).
