Description of for Water Treatment
WECHANG high flow filter cartridge are coreless, single open-ended filters that offer high filtration efficiency. These filters have a large diameter and laid over pleated cartridge with an inside-to-outside flow pattern that prevents debris from escaping the filter. The high flow rate at 1900 lpm or 500 gpm for a 60-inch length element allows for fewer cartridge change-outs.
