The ORE/A automatic self-cleaning screen filter line simplifies controls while increasing reliability and performance. Limit switches, reversing motors, extra contactors, second overload protection devices and complex controllers have been eliminated. Self-adjusting nozzles with no springs maintain light contact with the screen surface during the automatic rinse cycle for maximum cleaning and minimum water loss. The filter comes in sizes from 2 to 24 in. and filtration degrees from 5 to 3,000 µ.
