The Goodman 0162L00025 Bi-Flow Filter Drier is a genuine OEM refrigerant-circuit component for DCC3000313WMXXAA package units. A bi-flow drier filters and dries refrigerant in both directions of flow, making it ideal for heat-pump and reversing systems where refrigerant travels both ways through the line. It traps moisture, acids, and particulate contaminants that cause acid formation, capillary/TXV blockage, and compressor burnout — extending the life of the entire system.
The genuine Goodman drier is sized to your unit's line set and refrigerant charge, ensuring proper flow and filtration capacity. Generic driers may use undersized cores or mismatched connection diameters, restricting flow and reducing capacity. Replacing the drier whenever the system is opened is best practice — OEM guarantees the correct match.
Advanced — Requires refrigerant recovery, brazing the new drier into the line set, evacuation to vacuum, and recharging. This is a job for an EPA-certified HVAC professional. Do not attempt without proper tools and certification.
