Four Seasons A/C Accumulator P/N:33175

Keep your A/C system dry and clean with the Four Seasons A/C Accumulator 33175, a direct-fit replacement for the 1986-1993 Ford Aerostar (see the Buyer's Guide tab for engine applications). The accumulator/filter drier works on the low-pressure side of the air conditioning system, using a desiccant bag to remove moisture and trap contaminants that flushing alone can't clear — which is why it's replaced whenever the system is opened or serviced.

• Moisture & contaminant control: A desiccant bag absorbs moisture while the unit filters out debris circulating in the refrigerant.
• Leak-resistant build: Quality welds are used for a durable, leak-free design, with high-quality desiccant for appropriate absorption.
• Installation hardware included: The necessary gaskets, o-rings and seal are supplied for the job.
• Backed by experience: Built in an ISO/TS16949 & ISO14001 certified facility, drawing on over 50 years of mobile A/C experience.

A leaking or "open" system can saturate the desiccant bag within a few hours, making the accumulator/filter drier ineffective. Replacing this component is also required to validate many compressor warranties, so it should be renewed anytime the A/C system is serviced or a compressor is replaced.
