Airtex Automotive Division 7D0-820-191 A/C Receiver Drier

The Airtex Automotive Division 7D0-820-191 is an A/C receiver drier designed to maintain optimal air conditioning system performance. This essential component serves as both a reservoir for refrigerant and a filter to remove moisture and contaminants from the AC system.

Key Features:

• Removes moisture and debris from the refrigerant to protect system components
• Contains desiccant material that absorbs water vapor and prevents ice formation
• Filters out contaminants that could damage the compressor or expansion valve
• Stores excess refrigerant to ensure proper system operation
• Direct replacement for OEM part number 7D0-820-191

The receiver drier is a critical service component that should be replaced whenever the AC system is opened for major repairs, especially when replacing the compressor, condenser, or evaporator. Regular replacement helps prevent costly damage to other AC system components and ensures efficient cooling performance.
