• FOTI (filtration from outside to inside)

Working surface outside

The triangular shaped slot performing profiles are welded

with their wedge side to the inner crossbars. This

is the most frequent design which makes the outside

working surface smooth, thus allowing an easy cleaning

from acumulated solids.

Applied for filtration from the outside to the inside (FOTI) Used for filters with small gap openings (up to 10 micron). The profiles are welded on the outside of the inner support bars. The outside of the work surface is smooth. Small tolerances on the gap opening are achievable. An average of 10 microns is perfectly possible on a desired gap opening of 10 microns. This type of filter can be made in sizes between 45 mm as minimum diameter and 110 mm as maximum diameter. The maximum length is 1 m.

The smooth filter surface of the welded filter tubes ensures that the filter can be easily cleaned using either a scraper or brush as well as backwash. When using welded filter tubes, the customer is not bound to recurring costs, while paper and mesh filters are impossible to clean and therefore have to be replaced on a regular basis.
