Lennox 47W39 Filter Drier

The Lennox 47W39 Filter Drier is a critical liquid line refrigerant component engineered for high-pressure R410A system protection. Featuring a 5.1 cubic inch desiccant capacity, this OEM HVAC filter drier effectively captures moisture, acid, and solid contaminants that can lead to compressor failure or TXV clogging. Designed to meet the stringent demands of modern air conditioning and heat pump circuits, the Lennox 47W39 utilizes a high-density solid core desiccant to maintain refrigeration system efficiency and prevent the formation of harmful sludge and organic acids within the lineset.

For technicians performing a compressor replacement or a system burnout cleanup, installing this HVACR service part ensures the removal of non-condensables and debris that standard evacuation might miss. The robust steel shell is built to withstand high operating pressures, while the internal filtration pads provide superior particle retention, securing the long-term reliability of residential and commercial HVAC equipment.

• Optimal Contaminant Removal: Effectively traps moisture and neutralizes acids to protect the compressor and expansion valve (TXV).
• R410A Compatibility: Specifically rated for liquid line applications in systems using high-pressure R410A refrigerant.
• OEM Precision: Guaranteed Lennox replacement part fitment for seamless integration into existing condensuing units.
• 5.1 CU/IN Volume: Provides ample desiccant capacity for moisture sequestration in 1.5 to 5-ton systems.

• Where is the best location to install the Lennox 47W39? For maximum protection, it is recommended to install this drier in the liquid line as close to the expansion device as possible to guard against contaminants before they enter the evaporator.
• Do I need to replace the filter drier every time I open the system? Yes, veteran technicians recommend replacing the filter drier whenever the refrigerant circuit is opened for repair or maintenance to ensure the system remains dry and acid-free.
• Will this drier work for both air conditioners and heat pumps? This specific model is a unidirectional liquid line drier; check your system's flow requirements, as heat pumps may require a bi-flow drier if installed in a reversing section.
