Keep moisture and contaminants out of the A/C loop with the Four Seasons A/C Receiver Drier / Filter Drier 33471, a steel unit that installs as a direct-fit replacement for the listed applications: 1980-1982 and 1984-1988 MACK MS200P MID-LINER, 1981 and 1983-1988 MACK MS250P MID-LINER, 1981-1988 MACK MS300P MID-LINER, and 1981-1988 MACK MS300T MID-LINER. See the Buyer's Guide tab for engine details.

  • Filters the system: acts as a filter, removing moisture and contaminants that cannot be cleared by flushing.
  • Desiccant absorption: high-quality desiccant held in a desiccant bag draws moisture from the refrigerant circuit for appropriate absorption.
  • Steel construction: built with quality welds for a durable, leak-free design.
  • Install-ready: the necessary gaskets, o-rings and seal are included.

Because a leaking or "open" system can saturate the desiccant bag within a few hours and render the drier ineffective, replacing this component is essential whenever the A/C system is serviced. Four Seasons notes that replacement is also required to validate the compressor warranty. Backed by decades of mobile A/C manufacturing experience, this filter drier is produced in an ISO/TS16949 and ISO14001 certified facility.
