Copeland EK 306S – Liquid Line Filter Drier (3/4″ ODF)

The Copeland EK 306S is a premium compacted bead liquid line filter drier with a 20 micron outlet pad and 3/4″ ODF connections. Its desiccant blend removes moisture and acid, protecting compressors and expansion valves in refrigeration and air conditioning systems. It works with R-134a, R-404A, R-407C, R-410A, R-507, and older refrigerants such as R-22, and it is approved for POE oils with Copeland compressors.
