Keep your air conditioning refrigerant clean and dry with the Four Seasons A/C Receiver Drier, MPN 33532. This steel filter drier drops in as a direct-fit replacement across a wide range of INTERNATIONAL medium- and heavy-duty trucks, including the 1990-1995 4600, 1990-1997 4700, 1990-1997 4800 and 4900, 1981-1992 5070 and F5070, and 1988-1992 9300 — see the "Vehicles it fits" section for the full list of 33 applications.
Working as a filter within the A/C system, it removes moisture and contaminants from the refrigerant using its desiccant — debris that flushing alone cannot clear, which is why the drier is replaced whenever the system is opened or serviced.
- Steel construction: a durable steel filter drier housing.
- Quality welds: built for a durable, leak-free design.
- High-quality desiccant: absorbs moisture that can otherwise saturate a leaking or open system within hours.
- Installation hardware: the necessary gaskets, o-rings and seal are included.
Backed by Four Seasons' mobile A/C experience, this unit is intended to help protect the rest of the A/C system. Many manufacturers require replacing the drier anytime the system is serviced to validate the compressor warranty.
