    Keep your air conditioning system clean and dry with the Four Seasons A/C Receiver Drier 33728, a steel filter drier that installs as a direct-fit replacement on the 2007-2011 Western Star 4900EX, 4900FA, 4900SA, and 6900XD (see the "Vehicles it fits" section for engine-level details). It filters the refrigerant while its desiccant absorbs moisture and traps contaminants that flushing cannot remove, which is why replacing the drier is essential whenever the system is opened or serviced.

    • Steel filter drier: built with quality welds for a durable, leak-free design.
    • Desiccant absorption: uses high-quality desiccant to draw moisture out of the system; a leaking or "open" system can saturate the desiccant within a few hours and make the drier ineffective.
    • Filters contaminants: removes moisture and debris the refrigerant carries, helping protect the rest of the A/C system.
    • Install hardware included: necessary gaskets, o-rings and seal are included for easy installation.

    Produced in an ISO/TS16949 & ISO14001 certified facility and backed by Four Seasons' mobile A/C experience. Replacing the filter drier is required to validate compressor warranty and should be done any time the system is serviced.
