Andreae HE Filters: Two Filters in One with Synthetic Fibres

Filter Andreae HE

Filter Andreae HE




    This type of Andreae filter connects the advantages of an Andreae filter and a filter from synthetic fibres and thus it is regarded as two filters in one. The HE type has a layer of synthetic filter on the outlet side. In place of two filters enrolled in a row, two frames, double labour costs when swapping the filters and a larger inventory, it is possible to solve all this with Andreae HE filters. 

    Delivery: size 8 m2 x width 75, 90 and 100 cm.
