Product Description

The FILBUR MANUFACTURING FC-3112 is a replacement pool filter cartridge rated at 80 square feet of filtration area. It uses Reemay spunbond polyester media constructed with a continuous filament process that minimizes fiber migration and eliminates the need for chemical binders. This design preserves the full filtering surface area throughout the cartridge's service life. The media weight is 4 ounces, which provides a balance of flow rate and particle capture. The cartridge measures 13.19 inches long with a 7.87-inch outer diameter and a 3.06-inch top opening. It is installed and serviced by pool service technicians and knowledgeable pool system owners.

This cartridge is intended for use in residential and light commercial pool and spa filtration systems that accept an 80 square foot cartridge element. It is suited for cartridge filter housings requiring a top opening of approximately 3.06 inches and an outer body diameter of approximately 7.87 inches. The binder-free Reemay media is compatible with standard pool water chemistry and supports routine cleaning and reinstallation cycles typical of cartridge filter maintenance programs.
