Alco Controls W-48 Activated Carbon Filter Cartridge

Alco Controls W-48 Activated Carbon Filter Cartridge is a replaceable filter-drier core designed for Alco Controls ADK-Plus and FDH filter housings used in large commercial refrigeration and air‑conditioning systems. It combines an activated-carbon media with acid‑adsorption capability to remove moisture, acids, and soluble contaminants, while also targeting waxes and other hydrocarbons that can foul refrigerants. This configuration supports burnout cleanup and ongoing system protection by helping maintain refrigerant purity and preventing corrosive byproducts from circulating through compressors and oil paths. The W‑48 family is intended for heavy‑duty service in CFC, HCFC, and HFC refrigerant systems, and it is compatible with Alco Controls filter housings that require this core as a replacement. In practice, technicians deploy the W‑48 core to extend filter life, improve oil return efficiency, and reduce acid buildup in systems where robust contaminant removal is essential for reliable operation in commercial applications such as rooftop units, large non-residential chillers, and other industrial refrigeration equipment. By integrating activated carbon with high‑acid capacity media, the W‑48 cartridge delivers targeted purification that supports long‑term performance and cleaner refrigerant circuits.
