20" Big Depth Wound Poly Filter 1 Micron (20" x 4½")

Pentair Pentek WP-BB Series cartridges are manufactured in 10" and 20" lengths and in 4.5" diameters from a durable polypropylene cord that is wound around a rigid polypropylene core. The WP-BB cartridges are an economical solution to reduce fine sediment including rust, sand and scale particles.

The material in the WP-BB Cartridges is a fibrous polypropylene media wound in a precise pattern around a polypropylene core, providing greater surface area to maintain high flow rates. The WP-BB Cartridges are manufactured using an anti-static agent during the winding process to reduce the electrical charges produced during the winding process.

These string-wound cartridges are capable of withstanding temperatures up to 165°F (73.9°C), and will accommodate flow rates between 10 and 65 GPM with minimal pressure drop.

WP-BB Series Cartridges are suitable for a wide range of sediment applications including municipal and well water, are chemical resistant so they can be used with many industrial fluids.
