Description
The York S1-401372 is a genuine OEM BiFlow Filter Drier designed for use in heat pump and reverse-cycle refrigeration systems where refrigerant flow reverses direction during heating and cooling cycles. The HPC-305-S-HH model provides reliable moisture and contaminant removal in both flow directions, helping to protect compressors, expansion devices, and other critical system components from damage caused by acid, moisture, and particulates.
Key Features
- BiFlow design supports refrigerant flow in both directions — ideal for heat pump applications
- Removes moisture, acid, and solid contaminants from the refrigerant circuit
- Genuine York OEM replacement part (SKU: S1-401372)
- Helps protect compressors and metering devices from contamination-related failures
- Designed for direct drop-in replacement in compatible York systems
Application
This filter drier is engineered as a direct OEM replacement for York heat pump systems requiring a BiFlow filter drier. Its bidirectional filtration capability makes it well-suited for systems that reverse refrigerant flow between heating and cooling modes, ensuring consistent system protection year-round.
Why Use an OEM Filter Drier?
- Ensures compatibility with York system specifications
- Maintains system efficiency and refrigerant circuit integrity
- Reduces risk of moisture-related compressor failures
- Supports warranty compliance on York equipment
