Lennox 44W12 Filter/Drier for HVAC Refrigeration Systems

The Lennox 44W12 is a professional-grade filter/drier designed for use in air conditioning and refrigeration systems. This essential component serves dual purposes by removing moisture and filtering contaminants from the refrigerant circuit, helping protect compressors and other system components from damage.

Key Features:

• Removes moisture and acid from refrigeration systems
• Filters particulate contaminants to protect system components
• Desiccant core absorbs water vapor from refrigerant
• Designed for reliable performance in residential and light commercial HVAC applications
• Essential component for system installation and repair

Filter/driers like the 44W12 are critical during system installation, repair, or after compressor burnout to ensure clean, dry refrigerant flow. The molecular sieve desiccant captures moisture that could cause ice formation, corrosion, or acid buildup, while the filtration media traps debris that could damage valves, expansion devices, or the compressor itself.
