Copeland Comfort Control (Alco) 047603 Filter Drier

The Copeland Comfort Control (Alco) 047603 Filter Drier is a critical liquid line component engineered for high-moisture and contaminant removal in residential and commercial refrigeration systems. As a direct OEM replacement for 029-21710-000 and the Alco EK-053, this unit features a 5 cubic inch desiccant bead volume optimized for CFC, HCFC, and HFC refrigerants, including R-410A. The 3/8" flare connection ensures a mechanical, leak-resistant seal without the need for brazing, making it ideal for field repairs and routine maintenance. Rated for a 680 PSI maximum working pressure, this filter drier utilizes a 20-micron filtration pad to capture solid particulates like copper filings and carbon, preventing expansion valve orifice plugging and preventing acid formation. By maintaining a clean refrigerant liquid line, this EK series filter drier protects compressor integrity and ensures stable subcooling across the metering device.

Technical Benefits for Contractors

• Universal Refrigerant Compatibility: Designed to handle high-pressure synthetic oils (POE) and traditional mineral oils without compromising desiccant integrity.
• High-Efficiency Filtration: The 20-micron rating effectively traps system debris that can cause mechanical failure in reciprocating or scroll compressors.
• Superior Moisture Absorption: Large internal surface area provides maximum water capacity, preventing ice formation at the expansion valve.
• Direct OEM Specification: Ensures exact fitment and flow characteristics for York 029-21710-000 and primary Alco system configurations.
• Durable Construction: Shock-resistant steel shell capable of withstanding high-vibration environments in heavy-duty HVAC/R applications.

Common Questions

Is the Copeland 047603 compatible with R-410A systems?
Yes, with a maximum pressure rating of 680 PSI, this liquid line filter drier is fully compatible with high-pressure R-410A systems as well as R-22 and R-134a applications.

What is the difference between the Alco EK-053 and the Copeland 047603?
They are functionally identical. The 047603 is the specific part number used for wholesale and OEM distribution, while EK-053 refers to the Alco model prefix for a 5 cubic inch drier with 3/8" flare fittings.

Can this filter drier be installed in either direction?
No, this is a standard liquid line drier and is unidirectional. Technicians must follow the flow arrow stamped on the shell to ensure proper filtration and prevent internal bypass.
