Automatic Filters Inc. (Booth E12910) has developed automatic, self-cleaning water filters that the company said use much less rinse water than other filters in the market today.
``We developed a more efficient system,'' said President Gideon Brunn. Previously, in each cleaning cycle, ``a filter used 10-12 gallons; now, it's 1-2 gallons.'' The difference is saving and reusing rinse water.
The firm's Tekleen-brand filters avoid fouling heat exchangers, condensers or injection molds.
``Just fouling of 0.002 inch can cause an increase of 30 percent in water pumping costs,'' Brunn said. The firm began exploring the concept in 2000, went through multiple trial-and-error efforts and, last year, started finding the right combination. Without any flow interruption, a quick vacuum backwash cycle sucks dirt from the screen's inside.
Tekleen filters have a stainless-steel body and use various screen materials. The filters come in diameters of 1-24 inches and can handle flow rates of 5-12,000 gallons per minute. The labor and expense of replacing a screen, bag or cartridge is eliminated.
Automatic Filters was formed in 1985, employs 10 and occupies 10,000 square feet in Los Angeles. The plastics industry accounts for about one-fourth of the firm's business.
