This is a K2551-BB 50/50 GAC/calcite inline filter, by Omnipure. K2551-BB 50/50 GAC/Calcite Inline Filter Features: 10″ x 2″ Inline Filter 1/4″ FNPT Ports 0.5 GPM Flow Rate Used to Correct Low pH Water Maximum One-Year Service Life Omnipure K2551 is an inline Calcite and Corosex filter. The K2551 cartridge contains a 50/50 mix of Calcite and Corosex Media. Calcite is a crushed, white, screened marble used to neutralize acidic or low pH in drinking water. Corosex is a specially processed hard bead-like magnesia adapted for use in filters to neutralize acidity by increasing the pH value. The Calcite should be used only for pH levels 6.0 – 6.8 for the best use. For pH levels of 5.5-6.0, the calcite and corosex filter is best. The success of the K-Series filter is directly attributable to the innovative Quick-Connect fittings incorporated into the design. These fittings are unique in two ways. First, they allow for the installation of the inline filter in seconds. Inlet and outlet tubes are snapped and secured using a patented collet system. Second, the fittings are molded directly into the filter body and cap as a single unit. This reduces the chance of weeping or seepage. Cap and body are spin-welded together, producing a smooth, consistent seal without glues or binders that can cause contamination. These design and production techniques result in a reliable filter that is fast and easy to install. The K-Series filter is available in 6″, 8″, 10″, 12″, or 14″ lengths and manufactured in 2″ or 2.5″ diameters. The true benefit is that systems can be designed to incorporate the various lengths and diameters—all the same size or intermixed—to meet specific filtration needs.
