The accumulator/filter drier acts as a filter, removing moisture and contaminants from the A/C system — debris that flushing alone cannot clear, which is why replacement is essential during service.

• Moisture control: a desiccant bag absorbs moisture from the refrigerant; a leaking or open system can saturate the bag within hours, making the unit ineffective.
• Leak-free build: quality welds are designed for a durable, leak-free design, with high-quality desiccant for appropriate absorption.
• Ready to install: necessary gaskets, o-rings and seal are included.
• Proven experience: produced in an ISO/TS16949 & ISO14001 certified facility and backed by over 50 years of mobile A/C experience.

Replacing the accumulator/filter drier is required to validate compressor warranty and should be done anytime the system is opened or serviced.
