The Hurricane Filter Cartridge is designed to remove solids through a corrugated polyester -plus media that provides exceptional dirt holding capacity and maximizes flow. Dirt is distributed more evenly for longer filter runs and lower pressure drop. This media's exclusive blend of fibers will not shrink delaminate or migrate. A rugged PVC Core and the media are bonded to the end caps for high integral strength and long service lift. Cartridges will withstand 35 psi pressure differential. Cartridges can be cleaned and reused for months or even years.
