Four Seasons 33390 A/C Receiver Drier Steel Filter Drier

The Four Seasons 33390 is a steel A/C receiver drier (filter drier) designed as a direct-fit replacement for automotive air conditioning systems. Acting as both a filter and a desiccant unit, it removes moisture and contaminants from the refrigerant circuit to protect system components and maintain efficient cooling performance.

How It Works:

The receiver drier collects liquid refrigerant exiting the evaporator, filters out particulate contaminants, and absorbs moisture via an internal desiccant bag. Contaminants captured by the drier cannot be removed through flushing alone, making replacement an essential step whenever the A/C system is opened or serviced.

Key Features:

• Steel construction for durability and long-lasting service life
• High-quality desiccant for effective moisture absorption
• Quality welds provide a leak-free, durable design
• Male insert O-ring outlet fitting for secure, reliable connections
• Body length: 7.0 inches
• Manufactured in an ISO/TS16949 & ISO14001 certified facility
• 1-year warranty

Four Seasons, a division of Standard Motor Products, Inc., is the largest aftermarket mobile climate control parts supplier in the industry. All products are tested, validated, and inspected before leaving the facility. Replacing the receiver drier is required to validate compressor warranty and should be performed any time the A/C system is serviced.
