Copeland Comfort Control (Alco) 062829 Filter Drier

The Copeland Comfort Control (Alco) 062829, or AOFD553 Oil Filter Drier, is a high-performance solution engineered specifically for refrigeration systems utilizing POE oil. Because polyolester oils are highly hygroscopic, they rapidly absorb moisture which leads to acid formation and compressor failure; this hermetic oil filter drier prevents that degradation. It provides industry-leading 3-micron filtration to capture fine contaminants and uses a high-capacity XH-9 desiccant to ensure maximum moisture removal from the oil stream. Featuring 3/8" Male Flare connections for straightforward replacement, the unit is rated for a 680 PSI Maximum Working Pressure. Integrated dual access valves allow technicians to accurately monitor the pressure drop, ensuring the system maintains peak lubrication efficiency and long-term compressor protection.

• POE Oil Optimization: Specifically designed to clean and dry hygroscopic polyolester oils to prevent acid buildup.
• Precision 3-Micron Filtration: Provides superior particulate removal to protect internal compressor components from wear.
• Dual Access Ports: Features built-in valves for simplified pressure differential testing and system diagnostics.
• High Pressure Rating: Robust construction supports a 680 PSIG working pressure, suitable for a wide range of high-pressure refrigerants.
• Large Surface Area: The 55 cubic inch internal volume ensures high dirt-holding capacity and minimal pressure drop.

What refrigerants is the AOFD553 compatible with?
This oil filter drier is compatible with most HFC, HCFC, and HFO refrigerants, including R-134a, R-404A, R-407C, R-410A, and R-744 (CO2) systems within its pressure rating.

When should I replace the oil filter drier?
Technicians should check the pressure drop across the unit using the dual access valves. If the differential exceeds the system manufacturer’s limits or if a compressor burnout has occurred, replacement is required to maintain oil acidity control.

Can this be used on suction lines?
The AOFD553 is primarily designed for oil management lines to ensure that only clean, dry oil returns to the compressor crankcase.
