Description
The Carrier KH43LZ074 is a biflow filter drier designed for use in heat pump and refrigeration systems where refrigerant must flow in both directions. With a 3/8″ ODF connection, this filter drier provides reliable protection against moisture, acid, and particulate contamination throughout the refrigerant circuit, helping extend the life of system components and maintain peak efficiency.
Key Features
- Biflow design allows refrigerant flow in both directions — ideal for heat pump applications
- 3/8″ ODF sweat connections for easy field installation
- Removes moisture, acid, and solid contaminants from the refrigerant circuit
- Protects compressors, expansion valves, and other refrigeration components
- Genuine Carrier OEM replacement part (SKU: KH43LZ074)
- Compatible with common refrigerants used in residential and light commercial heat pump systems
Why Use a Biflow Filter Drier?
In heat pump systems, refrigerant reverses direction between heating and cooling modes. A standard unidirectional filter drier cannot accommodate this reversal, making a biflow filter drier essential. The Carrier KH43LZ074 is engineered specifically for this duty, ensuring consistent filtration and moisture removal regardless of the direction of refrigerant flow.
Application
- Residential and light commercial heat pump systems
- Refrigerant circuit protection during system service and changeouts
- Direct OEM replacement for Carrier equipment requiring KH43LZ074
