Copeland Comfort Control (Alco) 048217 Filter Drier

The Copeland Comfort Control (ALCO) 048217 Filter Drier, also identified as the EK307S, is a high-capacity liquid line filter drier engineered for demanding HVACR applications. This 30 cubic inch unit features a 7/8" sweat (ODF) connection, designed for secure integration into high-pressure systems with a maximum operating pressure of 680 PSI. Built with a 20-micron filtration rating and a specialized desiccant blend, it ensures the effective removal of moisture, acid, and solid contaminants that compromise compressor health. This OEM filter drier provides the structural integrity required for R-410A and other high-pressure refrigerants, serving as a critical safeguard against system sludge and freeze-ups at the expansion valve. For technicians performing retrofits or repairs, the EK-307S offers reliable moisture and acid removal to maintain oil stability and improve overall system longevity.

• Maximum System Protection: The 30 cubic inch core provides high water and acid capacity, essential for preventing compressor burnout.
• High-Pressure Ready: Rated for 680 PSI, making it fully compatible with modern R-410A refrigeration systems.
• Superior Filtration: Captures solid particles down to 20 microns to protect TXVs and capillary tubes from clogging.
• Durable Construction: Features 7/8" ODF sweat connections for leak-resistant, professional-grade brazing.
