Pentek SW-1A Wrench for Slim Line Housings

This Pentek 150539 SW-1A (previously SW-1) wrench is used to loosen the sumps of water filter housings. This wrench fits the sumps of Pentek Slim Line filter housings, which are used in a wide variety of applications, including drinking water purification, irrigation and industrial processes, among others. Water filters remove undesirable particles, chemicals and microorganisms from water by means of a semipermeable barrier, adsorption, or biological processes. They are 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 typically consist of a series of two or more types of filters, each designed to remove 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 flow rate and the amount of water that can be filtered before the filter must be replaced.
