Parker 11R30A 50 Micron String-wound Cartridge Filter 30in

Product Description

The PARKER 11R30A is a string-wound depth cartridge filter designed for plumbing and water treatment applications. It measures 2.5 inches in outside diameter and 30 inches in length, making it a high-capacity drop-in for standard filter housings used in commercial and residential water systems. The filter media is cotton wound in a graduated density pattern over a polypropylene plastic core, targeting particulate at a 50 micron rating. Plumbers and water treatment technicians install this filter to reduce sediment, rust, sand, and other suspended solids from potable or process water lines. The cotton media carries an FDA material grade, supporting use in food-service and drinking water contexts.

This filter is suited for sediment prefiltration in point-of-entry water treatment systems, well water installations, irrigation lines, and light industrial process water circuits. The 30-inch length provides extended service life compared to standard 10-inch or 20-inch cartridges, reducing changeout frequency in high-sediment environments. It fits housings designed for 2.5-inch OD, 30-inch cartridges and is rated for continuous service up to 120 degrees F. Installation is straightforward for any plumber or water treatment technician servicing filter housing assemblies.

Installation Notes

Installation should be performed by a licensed plumber or qualified water treatment technician in accordance with local plumbing codes and IPC guidelines.
