Pull moisture and debris out of your A/C loop with the Four Seasons A/C Receiver Drier (MPN 33994), a steel filter drier that drops in as a direct-fit replacement for the 2012-2024 Freightliner 108SD, 2011-2015 Freightliner M2, and 2012-2024 Freightliner M2 106. See the Buyer's Guide tab for engine-level fitment.

  • Steel construction: A steel filter-drier body built with quality welds for a durable, leak-free design.
  • Desiccant filtration: A desiccant bag absorbs moisture while the unit filters out contaminants that flushing cannot remove from the A/C system.
  • Install hardware: Necessary gaskets, o-rings, and seal are included for installation.
  • Backed by experience: Produced in an ISO/TS16949 and ISO14001 certified facility, drawing on Four Seasons' mobile A/C background.

The receiver/filter drier removes moisture and contaminants from the refrigerant circuit. A leaking or "open" system can saturate the desiccant bag within a few hours, making the drier ineffective. Four Seasons notes the drier should be replaced any time the system is opened or serviced, and that replacement is required to validate compressor warranty. If a saturated or restricted drier is behind your A/C trouble, this unit replaces it.
