The Airtex Automotive Division 64-50-9-202-689 A/C Receiver Drier is a critical component of your vehicle's air conditioning system. This receiver drier serves as both a filter and moisture removal device, protecting the A/C system from contaminants and water vapor that can cause corrosion and reduce cooling efficiency.

Key Functions:

• Removes moisture from refrigerant to prevent internal corrosion and ice formation
• Filters contaminants and debris from the A/C system
• Stores excess liquid refrigerant during operation
• Contains desiccant material that absorbs water from the refrigerant
• Protects compressor and expansion valve from damage

Important Service Notes:

• Should be replaced whenever the A/C system is opened for service
• Must be replaced if moisture contamination is suspected
• Recommended replacement during compressor or evaporator service
• Desiccant has limited moisture absorption capacity and cannot be regenerated

This receiver drier is manufactured to OEM specifications (BMW part number 64509202689) and ensures proper refrigerant flow and system protection. Regular replacement of the receiver drier helps maintain optimal A/C performance and extends the life of expensive system components.
