The Carrier P504-8083S Filter Drier is a bi-directional liquid line filter drier engineered for heat pump systems. This 8 cubic inch unit features 3/8 inch ODF sweat connections for reliable brazing. It handles CFC, HCFC, and HFC refrigerants, utilizing a desiccant blend of 75% molecular sieve and 25% activated alumina to remove moisture, acid, and solid contaminants down to 40 microns. This OEM replacement part, with a maximum working pressure of 680 PSIG and corrosion-resistant epoxy finish, maintains system integrity during heating and cooling cycles.
Bi-Flow Functionality: Internal check valves allow core filtration in both flow directions, essential for heat pump liquid lines.
Advanced Contaminant Control: Activated alumina and molecular sieve desiccant provide superior acid and moisture capacity.
High-Pressure Rated: Validated for maximum working pressure up to 680 PSIG, making it compatible with high-pressure refrigerants like R-410A.
