Fully Automatic Filtration

OptiFil 100 Backwash Filter

08.05.2015 The Optifil 100  backwash filter from Lenzing is a fully automatic, continuous system that works according to the principle of depth, surface or cake filtration. A metal fiber fabric or fleece is used as filter material which retains particles of different sizes either inside or on its surface. After the predetermined degree of contamination has been reached, the filter material is cleaned by backflushing with a small quantity of filtered medium.


Filtration is not interrupted during the backwash procedure. The regeneration system permits even the finest filter materials to be repeatedly cleaned on a long-term basis, ensuring a longer service life. The new filter offers much finer filtration than conventional backwash filters. Hitherto, filtration applications placing stringent demands on filtrate quality required a combination of backwash and bag (or candle) filters for pre-filtration of coarse particles. The fine separation achieved by this filter (mostly between 1 and 25 microns) now obviates the need for such high-maintenance equipment.  Individual applications range from automated parts cleaning to process filtration in a chemical plant, water filtration and coolant lubricant regeneration as well as high-viscosity fluids like dips and paints.
