Description
Trane DHY01545 Biflow Filter Drier
The Trane DHY01545 is a 5/16-inch biflow filter drier designed for use in refrigerant systems rated up to 5 tons. Built to Trane’s exacting quality standards, this filter drier effectively removes moisture, acid, and particulate contaminants from the refrigerant circuit, helping to protect compressors, expansion devices, and other critical system components from damage and premature wear.
The biflow design allows refrigerant to flow in either direction through the drier, making it ideally suited for heat pump applications where refrigerant flow reverses between heating and cooling modes. This versatility makes the DHY01545 a go-to solution for technicians servicing residential and light commercial heat pump systems.
Key Features
- Biflow design accommodates refrigerant flow in both directions — ideal for heat pump systems
- Rated for systems up to 5 tons capacity
- 5/16-inch connection size for easy installation
- Removes moisture, acid, and solid contaminants from the refrigerant circuit
- Helps protect compressors and metering devices from contamination-related damage

- Systems requiring bidirectional refrigerant flow filtration
Why Use a Biflow Filter Drier?
In heat pump systems, refrigerant flow reverses direction during mode changes. A standard unidirectional filter drier can restrict flow or lose effectiveness in reverse-flow conditions. The Trane DHY01545 biflow filter drier is engineered to maintain full drying and filtering performance regardless of flow direction, ensuring long-term system reliability and efficiency.
