Pentek WP25BB20P Polypropylene 4-1/2" x 20" String-Wound Cartridge

CW and WP Series cartridges are manufactured from a durable polypropylene cord that is wound around a rigid polypropylene core. They are an economical solution to reduce fine sediment, including sand, silt, rust and scale particles. CW cartridges are very economical and wound in a standard pattern around the core. They are available in 10, 30 and 50-micron ratings. WP Series cartridges are wound in a precise pattern around the core providing greater surface area. The result is higher dirt-loading capacity and greater ef!ciency than standard wound cartridges like the CW. Both of these string-wound cartridge styles are capable of withstanding temperatures up to 165ºF (73.9ºC), and will accommodate "ow rates between 7 and 10 GPM with minimal pressure drop. CW and WP Series cartridges are suitable for a wide variety of sediment !ltration applications, including municipal and well water as well as many industrial "uids.
