Pentair PNR Series Cartridges are manufactured from a polyester media, pleated around a polypropylene core for added strength. The pleated endcaps of the standard cartridges are immersed in a thermosetting vinyl plastisol. The Big Blue cartridges have a moulded endcap with gaskets. The pleated ends are sealed to the endcap with a thermoplastic adhesive. The overlap seam is sonically welded to reduce bypass, improving filtration efficiency. The high surface area of the pleated media provides a higher dirt holding capacity, high flow rates while maintaining extremely low pressure drop. Increasing the life of the cartridge between changes or cleaning due to the high surface area has the benefit of lowering the overall cost.
Pleated design maximises dirt holding capacity.
Designed for general water filtration process.
Versatile and re-usable, allowing for a variety of uses.
