Description
The Supco LLD084S is a liquid line filter drier engineered to safeguard refrigeration and air conditioning systems from the damaging effects of moisture, acid, and particulate contamination. Designed for installation in the liquid line of a refrigerant circuit, this drier works continuously to keep the system clean and dry, helping extend compressor life and maintain peak system efficiency.
How It Works
Liquid line filter driers are installed downstream of the condenser and upstream of the metering device. As refrigerant flows through the drier, the desiccant core captures moisture, acids, and solid contaminants before they can reach the expansion valve or compressor — two of the most vulnerable and costly components in any refrigeration system.
Key Features
- Liquid line design for installation between condenser and metering device
- Desiccant core absorbs moisture, acid, and particulate contaminants
- Helps protect compressors, expansion valves, and other system components
- Supports system efficiency and reliability over the long term
- Compact, durable construction suitable for residential and light commercial applications
- Supco quality backed by decades of HVAC/R component manufacturing expertise
Applications
- Residential and light commercial air conditioning systems
- Refrigeration equipment liquid line circuits
- New system installations and system changeouts
- Post-compressor burnout cleanup installations
Why Use a Liquid Line Filter Drier?
Moisture in a refrigerant circuit reacts with refrigerant oil to form corrosive acids that degrade system components and shorten equipment life. A quality liquid line filter drier is one of the most cost-effective ways to protect your investment and ensure long-term system reliability. The Supco LLD084S delivers dependable filtration and moisture removal in a straightforward, easy-to-install package.
