Parker 15R30 String-wound Cartridge Filter 20 Micron

Product Description

The PARKER 15R30 is a string-wound cartridge filter designed for plumbing and industrial fluid filtration applications. It measures 2.5 inches in outside diameter and 30 inches in length, with a 20-micron filtration rating that captures sediment, rust, scale, and particulate matter from water and compatible process fluids. The filter body is wound cotton, supported by a tinned steel core for structural integrity under pressure. It is rated for service up to 250 degrees F, making it suitable for both cold and hot water supply lines. Licensed plumbers and mechanical contractors are the primary installers for this type of cartridge.

This cartridge filter is used in residential, commercial, and light industrial plumbing systems where particulate removal is required ahead of downstream equipment such as water heaters, fixtures, or process equipment. Its 30-inch length and 2.5-inch outside diameter place it in the standard big-blue or equivalent large-format sump housing category. Applications include potable water filtration, process water conditioning, and pre-filtration for sensitive mechanical systems requiring clean supply lines.

Installation Notes

Installation should be performed by a licensed plumber in compliance with applicable local plumbing codes and IPC guidelines. Shut off the water supply and relieve system pressure before removing the filter housing and replacing the cartridge. Inspect the housing o-ring or gasket for wear during each cartridge change and replace if necessary. Do not exceed the rated temperature or flow specifications of the housing assembly in use.
