Airtex Automotive Division 911-573-939-02 A/C Receiver Drier

The Airtex Automotive Division 911-573-939-02 is an air conditioning receiver drier designed as a replacement for Porsche part number 911-573-939-02. This critical A/C system component serves three essential functions to keep your air conditioning operating efficiently and reliably.

Key Functions:

• Acts as a temporary storage container for refrigerant and oil during periods of low cooling demand
• Contains desiccant material that absorbs harmful moisture from the refrigerant to prevent corrosion and system damage
• Features an internal filter that traps debris and contaminants to protect downstream components

Technical Details:

• Compatible with both R12 and R134a refrigerants
• Replaces OEM part numbers 911-573-939-02 and 911-573-939-03
• Designed for models with receiver drier mounted in left front fender

The receiver drier is a serviceable component that should be replaced whenever the A/C system is opened for service, as the desiccant material becomes saturated when exposed to atmospheric moisture. Most compressor warranties require receiver drier replacement to ensure proper system protection and performance.
