CHICAGO (June 12, 1:55 p.m. EDT) — 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.
