Description
The Armstrong Furnace R101814-03 Drier Filter is a sealed inline unit that removes moisture, acid, and particulate from the refrigerant circuit before the fluid reaches the expansion valve and evaporator. Positioned along the liquid line of the refrigeration cycle, it acts as a protective barrier that prevents contaminants from circulating through the system and causing valve blockages or compressor damage. Within split-system and packaged HVAC systems, the filter drier preserves refrigerant integrity by absorbing trace amounts of water that enter the circuit during servicing or through minor seal degradation over time.
