The Sporlan 404380 RC-4864-HH is a high-performance activated charcoal filter drier core specifically engineered for aggressive system clean-up following a hermetic motor burnout. Designed with a 48 cubic inch desiccant volume, this replaceable core excels in wax removal and the neutralization of harmful acids and sludge that can compromise compressor longevity. It is fully compatible with Sporlan Catch-All shells ranging from the C-480 through C-19200 series, as well as RSF suction line shells. This technical-grade core utilizes a specialized desiccant blend to capture solid debris and moisture, ensuring that the Expansion Valve (TEV) and other sensitive metering devices remain free of contaminants. For technicians managing low-temperature refrigeration or commercial HVACR equipment, the RC-4864-HH is the industry standard for restoring system chemistry and preventing repeat failures after a major terminal or motor fault. Its porous molded construction provides a large filtering area, resulting in an exceptionally low pressure drop across the unit while maintaining high-capacity filtration of acids and resins. Key Benefits Advanced Burnout Recovery: Formulated with activated charcoal to aggressively remove acids, varnish, and sludge after a motor failure. Efficient Wax Removal: Optimized for low-temperature systems where wax flocculation can cause intermittent expansion valve sticking. High-Flow Architecture: Engineered with 64 square inches of filter area to ensure minimal pressure drop in both liquid and suction line applications. Broad Shell Compatibility: Fits standard 3.74" diameter canisters, including the Sporlan C-480 and RSF series replaceable shells. Complete Contaminant Control: Effectively captures moisture and solid debris to protect high-performance compressors and TEVs. Common Questions When should the RC-4864-HH be used instead of a standard RC-4864 core? The HH-series core should be selected specifically for systems requiring wax removal or heavy-duty clean-up after a burnout. While the standard RC-4864 is for routine moisture removal, the RC-4864-HH contains activated charcoal needed to pull resins and acids out of the oil. Is this core compatible with both POE and Mineral oils? Yes, the Sporlan RC-4864-HH is compatible with most modern refrigerants and lubricants, making it a versatile choice for retrofits and emergency service calls on both R-22 and HFC-based systems. Can these be used in the suction line? Yes, these cores are frequently used in RSF shells in the suction line during the clean-up process. Technicians should monitor the pressure drop across the shell and replace the cores once the pressure differential stabilizes or the system is clean.
