This steel filter drier draws on more than 50 years of Four Seasons mobile A/C experience. Inside the A/C circuit, it acts as a filter: a desiccant bag absorbs moisture, and the unit removes contaminants that flushing alone cannot clear. The part is listed under both names, A/C receiver drier and filter drier.

• Welded steel construction: quality welds designed for a durable, leak-free build.
• High-quality desiccant: provides appropriate absorption of moisture in the system.
• Seals included: the necessary gaskets, o-rings and seal come with the unit for easier installation.
• Certified production: engineered and tested by Four Seasons and produced in an ISO/TS16949 and ISO14001 certified facility.

When to replace: A leaking or open system can saturate the desiccant bag within a few hours, which leaves the drier ineffective. Replacement is required to validate the compressor warranty. The drier must also be replaced any time the A/C system is serviced.
