Nu-calgon 4623-40 High Flow Carbon Sediment Cartridge

Product Description

The NU-CALGON 4623-40 is a high flow carbon and sediment replacement cartridge designed for the Nu-Plus HFS filtration system. This cartridge handles dual-stage filtration by combining carbon media for chemical reduction with sediment filtration to remove particulate matter from water supplies. It is a direct replacement component intended for service technicians and water treatment professionals maintaining Nu-Plus HFS filter housings in HVAC, plumbing, or water treatment applications.

This replacement cartridge is suited for use in high flow filtration scenarios where both carbon and sediment removal are required. Typical installation settings include commercial and residential water treatment systems, HVAC equipment with water-side filtration requirements, and plumbing systems where water quality directly affects equipment performance and longevity. Service intervals vary based on water quality and flow demand.

Key Features
