Copeland Comfort Control (Alco) 063081 Filter Drier

The Copeland Comfort Control (Alco) 063081 Filter Drier, also identified as the Emerson Flow Controls BFK305S, is a high-capacity bi-directional liquid line filter drier engineered for thermal expansion valve (TXV) applications in heat pump and refrigeration systems. Featuring a 30 cubic inch desiccant volume and a 5/8" sweat (ODF) connection, this unit provides critical moisture and acid removal while ensuring a 40-micron filtration level to protect internal components from particulate debris. With a maximum working pressure of 680 PSI, it is compatible with modern high-pressure refrigerants including R-410A. The internal check valve design allows for bi-flow operation, eliminating the need for external check valves in reversing cycles while maintaining peak system efficiency. This OEM component is built with a rugged steel shell and a premium desiccant blend optimized for high water and acid capacity, ensuring the long-term cleanliness of the refrigeration circuit.

Technical Benefits for Contractors

• Bi-Flow Functionality: Integrated check valves prevent the release of captured contaminants back into the system during flow reversal, making it essential for heat pump liquid lines.
• High-Pressure Tolerance: Rated for a 680 PSI maximum pressure, providing a significant safety margin for R-410A and high-ambient refrigeration environments.
• Standard Porting: The 5/8" ODF sweat connection facilitates easy brazing into standard copper liquid lines, reducing installation time for technicians.
• Superior Filtration: A 40-micron internal filter ensures that small particulates do not reach the TXV or orifice, preventing common capillary tube clogging issues.
• Chemical Protection: Desiccant core effectively sequesters moisture and neutralized acids, preventing compressor motor burnout and copper plating.

Common Questions

Is the 063081 compatible with both R-22 and R-410A systems?
Yes, the 063081/BFK305S is designed to handle the higher operating pressures of R-410A while remaining fully compatible with R-22 and other common HFC/HCFC refrigerants.

Does this drier require external check valves when installed on a heat pump?
No, the bi-directional design includes internal check valves, allowing the drier to filter the refrigerant in both heating and cooling modes without additional piping complexity.

What is the difference between the 063081 and the BFK305S?
They are technically identical. The 063081 is the specific part number often used under the Copeland/Alco brand, while BFK305S is the standard Emerson Flow Controls model designation.
