Global Filtration Systems will display its line of patented self-cleaning filtration systems, carbon treatment units and oil-extraction systems. AF-Series backflushing filter systems allow for superior filtration without disassembly for cleaning, the company says. Permanent media is periodically backflush cleaned using a patented design and a short, five-minute cycle, without solution loss. In addition, all systems are offered in both manual and fully automated configurations. With standard flow rates to 500 GPM and temperatures to 180°F, these systems resist the effects of corrosive chemicals and other hostile fluids. Systems are produced in all-plastic, non-corrosive construction and are designed for a multitude of aggressive chemicals as well as process water.
