Keep your A/C system clean and dry with the Four Seasons A/C Receiver Drier / Filter Drier 33474, a steel filter drier that drops in as a direct-fit replacement for the listed applications: 1999-2005 MACK CH, 2004-2006 MACK CHN, 1999-2005 MACK CX, and 2004-2005 MACK CXN. See the Buyer's Guide tab for engine-level fitment details.

This part is listed under both names — A/C Receiver Drier and Filter Drier. It acts as a filter, removing moisture and contaminants from the air conditioning system — contaminants that cannot be cleared by flushing, which is why replacing the drier is essential whenever the system is opened.

  • Steel construction: a steel filter drier body with quality welds for a durable, leak-free design.
  • Moisture absorption: a desiccant bag absorbs moisture from the system; a leaking or open system can saturate the bag within hours, making the drier ineffective.
  • Installation hardware: the necessary gaskets, o-rings and seal are included for easier installation.
  • Backed by experience: produced in an ISO/TS16949 & ISO14001 certified facility, drawing on over 50 years of mobile A/C experience.

Replacing the filter drier is required to validate compressor warranty and should be done anytime the system is serviced.
