York S1-401372 Filter Drier

The York S1-401372 Filter Drier, specifically the HPC-305-S-HH model, is a heavy-duty bi-flow filter drier engineered for high-capacity heat pump applications. For technicians managing R-410A system contaminants or performing a burnout cleanup, this unit provides 30 cubic inches of high-performance desiccant material. Unlike standard directional driers, the York S1-401372 features internal check valves that ensure bi-directional refrigerant flow without washing trapped debris back into the liquid line. This 5/8 ODF sweat connection drier is built for 8 to 20-ton systems, maintaining a low pressure drop while aggressively removing moisture, acid, and solid particulate. Utilizing an "HH" charcoal core, it excels at adsorbing wax and sludge, critical for protecting the TXV and compressor during heat pump liquid line filter drier replacement. With a 650 PSIG maximum working pressure, it meets the rigorous demands of modern high-pressure refrigerants, ensuring system stability and chemical purity in the field.

Key Benefits:

• Dual-Flow Engineering: Integrated internal check valves allow for seamless operation in both heating and cooling cycles without re-introducing contaminants.
• Enhanced Acid Removal: The activated charcoal "HH" core is specifically designed to neutralize wax and acid following a compressor burnout.
• High-Pressure Rating: Rated for a maximum working pressure of 650 PSIG, making it compatible with high-pressure R-410A heat pump systems.
• Optimal Filtration Media: Features a solid core desiccant that minimizes pressure drop while maximizing moisture removal capacity.
• Rugged Construction: Corrosion-resistant epoxy powder coating ensures the shell maintains integrity in harsh outdoor environments.

Common Questions:

• When should I replace the York S1-401372? This liquid line drier must be replaced whenever the refrigerant circuit is opened for service, or if a temperature drop exceeding 3°F is measured across the inlet and outlet.
• Can this be used on R-22 systems? Yes, while optimized for modern refrigerants, the HPC-305-S-HH is compatible with most HFC and HCFC blends, including R-22, R-134a, and R-404A.
• What is the purpose of the "HH" core designation? The "HH" core contains extra desiccant and charcoal specifically for system cleanup, making it the preferred choice for dealing with burnt-out compressors or heavily sludge-contaminated lines.
