Description
Copeland BFK084S Bi-Directional Liquid Line Filter Drier
The Copeland BFK084S (SKU 043327) is a high-performance bi-directional liquid line filter drier engineered to protect refrigeration and air conditioning systems from moisture, acid, and particulate contamination. With its bi-directional flow design, this filter drier is ideally suited for heat pump applications where refrigerant flow reverses between heating and cooling cycles, eliminating the need to install separate driers for each flow direction.
Key Features
- Bi-directional flow design — ideal for heat pump and reversing refrigerant systems
- 1/2″ sweat (ODF) connections for easy, leak-free copper line installation
- 8 cubic inch internal volume for robust moisture and acid absorption capacity
- 40 micron filtration rating removes harmful particulates and debris from the refrigerant circuit
- 680 PSI maximum working pressure for safe operation across a wide range of refrigerants and system pressures
- Desiccant core effectively removes moisture and acids to protect compressors, valves, and metering devices
- Compact, durable shell construction built to withstand demanding field conditions

Why Use a Liquid Line Filter Drier?
Moisture and acid contamination are leading causes of compressor failure and system inefficiency. The Copeland BFK084S filter drier acts as the last line of defense before the refrigerant reaches the metering device and evaporator, capturing moisture, acids, and particulates that can cause corrosion, copper plating, and premature component wear. The bi-directional capability ensures continuous protection regardless of refrigerant flow direction, making it the preferred choice for heat pump installations.
