The Sporlan 401307 C-304-S Filter Drier is an industry-standard liquid line filter drier designed for high-capacity moisture and acid removal in commercial and residential systems. Featuring a 30 cubic inch desiccant volume and 1/2 ODF (Outside Diameter Flare) solder connections, this unit is engineered for systems ranging from 2 to 10 tons. The Sporlan Catch-All C-304-S utilizes a unique molded porous core made of a specialized blend of desiccants, providing a 650 psig maximum working pressure. This makes it fully compatible with modern R-410A refrigerant as well as HFC, HCFC, and HFO blends. For technicians, the 401307 is identical to C-304-S, ensuring a direct drop-in replacement that maintains low pressure drop while capturing scale, solder particles, and carbon. The epoxy powder-coated shell provides corrosion resistance in demanding environments, protecting the 53 square inches of internal filtering area from external degradation. Key Benefits Unmatched Contaminant Control: The molded core captures solid debris down to 20 microns, protecting the TEV and compressor from premature wear. High Acid Capacity: Specifically formulated to adsorb hydrochloric, hydrofluoric, and organic acids, preventing oil breakdown and motor burnout. Optimized Flow: Designed for high-flow performance with negligible pressure drop, maintaining system efficiency during peak loads. Versatile Compatibility: UL Listed for high-pressure applications, including R410A filter drier replacements and sub-critical CO2 systems. Common Questions Is the Sporlan 401307 compatible with R-22 and R-404A? Yes, the C-304-S is rated for all major refrigerants, including R-22, R-134a, R-404A, R-507, and R-410A high-pressure systems. Can this drier be used for bi-directional flow in heat pumps? No, the C-304-S is a dedicated liquid line drier. For heat pump applications requiring filtration in both heating and cooling modes, a Sporlan HPC series bi-directional drier should be specified. What is the difference between 401307 and C-304-S? There is no technical difference; 401307 is the specific Parker/Sporlan part number for the C-304-S model with 1/2" ODF connections.
