Nu-calgon 4621-32 Nu-plus 4CB5 Carbon Block Water Filter 6000 Gallon

Product Description

The Nu-Calgon 4621-32 is a Nu-Plus 4CB5 carbon block water filter designed to deliver high-quality water for beverage and food service applications. Carbon block filtration is one of the most effective methods for removing contaminants from water. The dense block structure forces water through tightly packed activated carbon, which traps chlorine, taste compounds, odor-causing substances, and fine particulate matter. The result is cleaner, better-tasting water that meets the demands of commercial food service equipment, ice machines, coffee brewers, and similar applications where water quality directly affects end product quality.

The Nu-Calgon 4621-32 is NSF Certified under NSF Standard 42, which covers aesthetic effects including taste, odor, and chlorine reduction. This certification gives facility managers, technicians, and inspectors confidence that the filter performs to a verified standard. For HVAC and refrigeration technicians who service commercial kitchen equipment or ice machines, this filter is a reliable choice for maintenance and replacement work.

This filter reduces particulate matter down to 5 micron. That level of filtration captures sediment, rust particles, and fine debris that can foul equipment components, clog valves, and shorten the service life of downstream equipment. With a rated capacity of 6,000 gallons, the 4621-32 provides extended service intervals, reducing the frequency of filter change-outs and overall maintenance labor. Plumbers and service technicians working in commercial accounts will appreciate the combination of high capacity and proven filtration performance. The carbon block construction is compact and designed to fit standard filter housings used in point-of-use water treatment systems.
