Pentek CW-MF String-Wound Polypropylene Filter Cartridge, 9-7/8″ x 2-1/4″, 30 Micron

This Pentek CW-MF string-wound polypropylene filter cartridge reduces sand, silt, scale, and rust particles for municipal drinking water and industrial fluid applications. It has a nominal filtration rating of 30 microns at an efficiency of 85%. The filter is made of polypropylene fiber cord that is wound on a rigid polypropylene core for greater surface area for strength and high dirt-loading capacity. It has an initial pressure drop of less than 1 pound per square inch (psi) at a maximum go with the flow rate of 10 gallons per minute (gpm), and operates over a temperature range of 40 to 145 degrees F (4.4 to 62.8 degrees C). This string-wound filter cartridge is to be used in more than a few applications, including drinking water purification, irrigation, and industrial processes, among others.

Specifications

The nominal filtration rating is for a particle removal efficiency of 85%.

H is height, the vertical distance from lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back.

Water filters remove undesirable particles, chemicals, and microorganisms from water by the use of a semipermeable barrier, adsorption, or biological processes. They’re made of densely packed synthetic or natural fibers that trap suspended particles, materials that block microbes or adsorb unwanted chemicals, or substances that cause a chemical change, such as acid neutralization. For most residential, commercial, and industrial applications, water filters are manufactured in the form of replaceable cartridges that fit inside permanent housings. Filtration systems in most cases consist of a series of two or more types of filters, each designed to take away different contaminants. The performance of filters is measured by the minimum particle size that is blocked, the percentage of particles or microorganisms that are removed, the downstream concentration of unwanted chemicals, the maximum go with the flow rate, and the amount of water that may be filtered before the filter will have to be replaced. Water filters are used in quite a lot of applications, including drinking water purification, swimming pools, industrial processes, and irrigation, among others.
