Carrier P502-8164S Filter Drier

The Carrier P502-8164S is a high-capacity liquid line filter drier engineered for heavy-duty moisture and acid removal in commercial and residential HVACR systems. Designed as a 16 cubic inch filter drier, this unit features a 1/2" ODF (solder) connection, ensuring a secure, leak-free fit for high-pressure applications. The internal filtration media consists of a 75% molecular sieve and 25% activated alumina desiccant blend, optimized for maximum adsorption of water and neutralization of destructive acids. A 20-micron outlet pad provides final stage particulate filtration, preventing contaminants from reaching the expansion valve or compressor. With a 650 psig maximum working pressure, this uni-directional drier is a robust HVAC replacement part compatible with a wide range of refrigerants including R-410A, R-22, and R-134a. This OEM-spec Totaline P502-8164S ensures system dehydration and longevity for professional contractors performing critical maintenance.

• Universal Refrigerant Compatibility: Approved for use with CFC, HCFC, and HFC refrigerants, including R-410A and R-22.
• High Acid Neutralization: The 25% activated alumina content effectively captures organic acids to prevent motor burnout.
• Superior Moisture Capacity: 16 cu. in. volume provides ample desiccant surface area for deep system dehydration.
• Rugged Construction: Rated for 650 psig to handle modern high-pressure 410A systems without deformation.
• Simplified Installation: 1/2" ODF solid copper connections allow for standard brazing techniques without overheating the desiccant.

Is the Carrier P502-8164S bi-directional?
No, this model is a uni-directional liquid line drier. Always ensure the flow arrow on the canister points toward the metering device to maintain proper filtration performance.

What is the filtration rating of the outlet pad?
This drier utilizes a fine 20-micron outlet pad to trap small copper shavings, scale, and other debris before they can impact system orifices.

Can this drier be used on a suction line?
This is a dedicated liquid line drier. For compressor protection after a burnout, a specifically rated suction line drier with pressure taps is recommended.
