Parker 11R30 String-wound Cartridge Filter 50 Micron

Product Description

The PARKER 11R30 is a string-wound cotton cartridge filter designed for plumbing and water filtration applications. It measures 30 inches in length with a 2.5-inch outside diameter, and delivers 50-micron particulate filtration suitable for sediment removal in commercial and residential water systems. The cotton winding over a tinned steel core provides mechanical filtration of dirt, rust, scale, and other suspended solids. Rated for a maximum working temperature of 250 degrees F, this cartridge handles hot-water service lines as well as standard cold supply systems. Licensed plumbers and water treatment technicians are the primary installers.

The 11R30 is suited for use in standard 30-inch filter housings across a wide range of plumbing installations, including process water lines, pre-filtration stages ahead of water softeners or UV systems, and point-of-entry sediment reduction. The 50-micron rating targets coarse-to-medium particulate loads. The cotton construction is compatible with many common water chemistry conditions, and the tinned steel core resists corrosion under normal service. Applications span light industrial, commercial food service, and residential whole-house filtration setups.
