Emerson Alco 062963 Filter Drier

For professional contractors demanding peak system reliability, the Emerson Alco 062963 (Model ASF28S7) delivers industrial-grade protection for the compressor's suction side. Engineered as a high-capacity suction line filter drier, this 28 cubic inch unit is purpose-built to capture and retain solid contaminants like scale, weld slag, and carbon before they reach the crankcase. Featuring a 7/8" sweat (ODF) solid copper connection, it integrates seamlessly into the refrigerant piping while minimizing pressure drop. The internal filtration media is rated at 40 microns, providing a critical defense against particulate matter that causes premature valve failure. With a 500 PSI maximum pressure rating and dual access valves for accurate suction line pressure drop monitoring, this HVAC filter drier is compatible with all major HCFC and HFC refrigerants, including R-22 and R-410A. Its corrosion-resistant epoxy powder finish ensures long-term durability in demanding environments.

• Internal 40 Micron Filtration: Effectively traps dirt and metallic particles that standard liquid line driers might miss.
• Dual Access Valves: Simplifies the process of measuring pressure differentials across the drier to determine system health.
• High Acid/Moisture Capacity: The 28 cubic inch desiccant volume provides ample surface area for cleaning up systems after a burnout.
• Rugged Shell Construction: Tested for a 500 PSI maximum working pressure to ensure safety in high-pressure air conditioning and refrigeration applications.
• Solid Copper Connections: Prevents oxidation during the brazing process and ensures a leak-free 7/8" ODF fit.

• Can this be used on both the liquid and suction lines? No, the ASF28S7 is specifically optimized for suction line service with a low-pressure-drop design to protect the compressor heart.
• Is this compatible with POE and Mineral oils? Yes, the Emerson Alco 062963 is fully compatible with modern polyolester and traditional mineral lubricants used in HVACR systems.
• How do I know when to replace this filter drier? Using the integrated access ports, a technician should replace the unit if the measured pressure drop exceeds the manufacturer’s recommended limits for the specific refrigerant.
