The Forty-X™ Disc Filter is a high-rate filtration device that utilizes an innovative woven polyester pleated filter panel design. The pleated filter panel provides significantly more filtration area than any other woven media flat panel designs and includes a specified micron absolute media rating. The pleated panel configuration is stronger than comparable designs and includes a robust pressure-assisted seal that allows the panel to sustain and operate at a higher headloss of any other flat panel disc filter. Our filter panels are also housed in a trash tolerant filter panel housing, which assures the unhindered flow of water between panels and rejects plastics, algae clumps or other floatables.
