Lennox 12L74 Catch-All Liquid Line Filter Drier 5/8" ODF

The Lennox 12L74 is a professional-grade Catch-All liquid line filter drier designed for residential and commercial air conditioning and refrigeration systems. This sealed model features 5/8" ODF solder connections, 30 cubic inches of desiccant volume, and measures 9.25" in length, making it suitable for systems up to 16.9 tons.

Advanced Filtration Technology:

• Moisture Removal: Utilizes a specially formulated blend of molecular sieve and activated alumina desiccants that adsorb and retain moisture deep within the granules, protecting expansion valves from freeze-up
• Acid Removal: Superior capability to remove hydrochloric, hydrofluoric, and organic acids from refrigerant systems, protecting system components from corrosion
• Particulate Filtration: Effectively filters scale, solder particles, dirt, and foreign matter that could damage compressors, solenoid valves, and expansion valves
• Oil Breakdown Protection: Unique desiccant blend removes products of lubricant decomposition, making it highly effective for system cleanup after hermetic motor burnout
