Poly Fine XLD Filter Cartridges

Summary

Product identification

The Poly-Fine® XLD Series Filter Cartridges are absolute-rated, extended life depth filters featuring proprietary Gel Guard filter media. They incorporate an innovative merger of depth and pleated technologies, offering high surface area for long service life. These filters are constructed with micro denier melt blown fibers for high efficiency filtration and are designed for high flow rates with low pressure drops. The entire construction is polypropylene.

Flow vs. differential pressure

A graph illustrating typical flow vs. differential pressure for application sizing is provided in the official document. Flow rate is per 10" (25.4 cm) cartridge. For liquids other than water, multiply differential pressure by fluid viscosity (cP).
