Why Use a Liquid Line Filter Drier?
Installing a quality liquid line filter drier is one of the most important steps in protecting a refrigerant system. The Copeland EK306S removes moisture that can form damaging acids, filters out metallic particles and debris from the refrigerant stream, and helps prevent compressor damage and system failure. The 20-micron rating ensures thorough filtration without restricting flow, while the 680 PSI maximum pressure rating makes it suitable for use with modern high-pressure refrigerants. The 3/4″ sweat connections allow for fast, professional installation on new systems or during service and changeouts.
