Description
The AAON G005560 is an OEM replacement biflow filter drier designed for use in AAON commercial HVAC and refrigeration systems. Identified by model number HPC-307C-S, this filter drier is engineered to protect refrigerant circuits by removing moisture, acid, and particulate contamination from the refrigerant stream in either flow direction — making it ideal for heat pump and reversible refrigeration applications where refrigerant flow reverses between heating and cooling modes.
Key Features
- Biflow (bidirectional) design accommodates refrigerant flow in both directions
- Removes moisture, acid, and solid contaminants from the refrigerant circuit
- OEM replacement part engineered to AAON specifications
- Helps extend compressor life and maintain system efficiency
- Suitable for heat pump and reversible refrigeration systems
- Direct drop-in replacement for AAON equipment using the HPC-307C-S drier
Application
This filter drier is a genuine AAON replacement component intended for use in AAON rooftop units and commercial HVAC equipment. Biflow filter driers are a critical component in heat pump systems, protecting the refrigeration circuit during both the heating and cooling cycles by filtering contaminants regardless of refrigerant flow direction. Using the correct OEM-specified drier ensures compatibility, optimal moisture removal capacity, and long-term system reliability.
Why Replace Your Filter Drier?
- Saturated or clogged driers restrict refrigerant flow and reduce system efficiency
- Moisture in the refrigerant circuit can cause acid formation, damaging compressors and valves
- Routine drier replacement during service calls is recommended best practice
- Using the correct OEM part ensures proper fit and rated performance
