Application
The Copeland ASD45S7W suction line filter drier is recommended for installation on the suction side of the compressor to capture contaminants before they can enter and damage the compressor. It is especially critical following a compressor burnout, where acid and carbon deposits must be removed from the system to ensure reliable operation of the replacement compressor. The 40 micron filtration media and desiccant core work together to remove both solid particles and moisture, safeguarding system components and refrigerant quality.
