Pleated Activated Carbon

The Pleated Activated Carbon (PAC) cartridge from Nelsen's Red Series brings true dual-action performance to commercial water treatment, combining mechanical pleated filtration with the chemical-adsorption power of activated carbon in a single high-capacity cartridge. Engineered for high-demand environments, it tackles the chlorine, sediment, and aesthetic problems that quietly compromise water quality across light-industrial, food-service, hospitality, and multi-unit settings where both clarity and taste matter.

Carbon Filtration That Improves Every Glass

Activated carbon works by drawing dissolved chlorine and organic compounds onto its enormous internal surface area through a process called adsorption. As water passes through, off-tastes and foul odors are reduced at the same moment the pleated structure traps suspended particulate. The outcome is noticeably cleaner, fresher water without the harsh chemical edge that untreated municipal supplies so often carry, and without the cloudiness that sediment leaves behind.

• Rated for a 15 gpm service flow in commercial Red Series housings
• Generous removal capacity of approximately 140,000 gallons before changeout
• Delivers up to 90% chlorine reduction for markedly better taste and odor
• Pleated design maximizes surface area and dirt-holding capacity
• 100% cellulose-free media construction for broad chemical compatibility
• Reduces chlorine, off-tastes, odors, and sediment in a single pass

As part of Nelsen's broader Red Series of pleated polypropylene cartridges, the PAC slots into the same commercial housings that accept the system's straight-sediment pleated options, which range up to 150 gpm service flow with a low pressure drop of less than 15 psi. That shared compatibility gives facility managers real flexibility to dial in exactly the level of treatment a building needs, staging coarse sediment removal ahead of carbon polishing. Routine replacement is straightforward, and the high gallon capacity means longer intervals between service calls. When taste and odor matter as much as particle removal, this Nelsen carbon cartridge is a dependable, long-running cornerstone of commercial filtration.

Because the PAC cartridge handles both chemical and physical contaminants together, it can simplify a treatment train that might otherwise require separate carbon and sediment stages, saving space in tight equipment rooms and reducing the number of components a technician has to service. A gradual return of chlorine taste or a rising pressure drop signals that the carbon is nearing capacity. For commercial buyers, the PAC pairs single-cartridge convenience with aesthetic improvements that customers, staff, and equipment all benefit from.
