Keep the A/C on the 1994-2003 MACK MR moving clean, dry refrigerant with the Four Seasons A/C Receiver Drier / Filter Drier, MPN 33466. This steel filter drier drops in as a direct-fit replacement for the listed applications, removing moisture and contaminants that can't be cleared by flushing alone — which is why the drier is replaced whenever the system is opened or serviced.

  • Steel construction: a steel filter drier built in an ISO/TS16949 & ISO14001 certified facility for consistent product integrity.
  • Quality welds: welded for a durable, leak-free design.
  • Desiccant bag: high-quality desiccant absorbs moisture from the system; a leaking or "open" system can saturate the bag within hours, so it should be replaced with service.
  • Installation hardware: the necessary gaskets, o-rings and seal are included for the install.

Acting as a filter, it removes moisture and contaminants circulating in the air conditioning system. Backed by over 50 years of Four Seasons mobile A/C experience, it's designed to be replaced anytime the system is serviced to help validate the compressor warranty.
