Precoating “BF protection” can increase the performance of textile and pleated filter elements and protects the filter element thanks to its special structure.
The pre-coating powder shall be introduced after the installation of new filtering elements in the filtration system and form a supporting filtering layer on the surface of the new elements. The first filtering support layer, consisting of a multitude of pores, prevents the entry of dust particles into the filtration medium and, therefore, effectively prevents clogging or effective cracking with the filtering medium. This protective layer increases the efficiency of the system, reduces fouling, improves cleaning and can prolong the useful life of the filtering elements.
In addition, the coating powder is lighter than the lime usually used and does not separate from the filtration elements during dedusting.
PRE-TREATMENT IS ESSENTIAL FOR THE FILTRATION OF DUST FROM PROCESSES SUCH AS:
- Laser cutting
- Plasma cutting
- Metallisation (aluminium, zinc, nickel, etc.)
- All cases with low concentrations of phyto
- All cases with presence of oil
- All cases with sticky powders
