A/C Receiver Drier for 2019-2024 Mack Terrapro & More - Four Seasons 33475

Help keep moisture and contaminants out of your truck's air conditioning system with the Four Seasons A/C Receiver Drier / Filter Drier 33475, a steel drier that absorbs moisture with a desiccant bag. It fits many Mack and Volvo trucks, among them the 2008-2011 Mack CXU, the 2008-2011 Mack CHU and the 2019-2024 Mack TerraPro. See the "Vehicles it fits" section for the full list.

Four Seasons describes this part as a steel filter drier, and it is also cataloged as an A/C receiver drier. It is listed under both names.

• Filters the A/C system: The drier removes moisture and contaminants from the air conditioning system. Flushing cannot remove these contaminants, so Four Seasons calls replacing the drier essential.
• Desiccant moisture absorption: High-quality desiccant in a desiccant bag absorbs moisture. A leaking or "open" system can saturate the bag within a few hours, which leaves the drier ineffective.
• Welded steel construction: Quality welds give the unit a durable design intended to be leak-free.
• Installation seals included: The necessary gaskets, O-rings and seal are included to make installation easier.

Four Seasons accumulators and filter driers are produced in an ISO/TS16949 and ISO14001 certified facility with state-of-the-art equipment and high-quality materials. They are backed by more than 50 years of mobile A/C experience. Replacing the drier is required to validate the compressor warranty, and the drier must be replaced any time the system is serviced.
