hengshui guangxing screens Co.,ltd can now offer welded wedge wire slot tubes with a tolerance on the slot opening of +/- 10 micron. Because of these small tolerances, we can now even produce filter cartridges with a slot opening of 10 micron. Very tight tolerances on the slots, result in a very accurate filtration process. With these tolerances, the filtration process with the bigger slot openings will now also be far more accurate then before.

Our wedge wire cartridges with 10 micron, can be used in air, dust and gas filtration, where they can replace the existing paper and mesh filters. Some conditions to produce 10 micron:

Diameter of the filter: from 45 mm up to 110mm

OD 45 mm →  70 mm: max. length 2000 mm

OD 70 mm →  110 mm: max. length 1000 mm

Filtration has to be from outside to inside (FOTI)

Used profile wire has to be 0,76 mm wide

Advantage of WEDGE WIRE FILTERS

The smooth filtering surface of the wedge wire filters helps easy cleaning, by wiping of or by backwash, where for paper and mesh filters cleaning is never efficient or sometimes impossible. There are no recurring expenses in case of welded wedge wire candles, where paper and mesh filters are disposable and need to be replaced. The slot opening of wedge wire filters always remains constant, where for paper and mesh filters the slot opening may widen or get disturbed.

• 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.
