FILTER-DRIER AND ACCUMULATOR

The Behr AD 207 000S is an A/C receiver drier designed to filter moisture and debris from the refrigerant in air conditioning systems that utilize a thermal expansion valve. This component is crucial for maintaining efficient operation and preventing damage to other A/C system parts. It is located on the high-pressure side of the system.

This receiver drier should be replaced whenever the A/C system is opened for repairs or component replacement, as the desiccant inside can become saturated with moisture from atmospheric exposure. Regular replacement ensures the system remains dry and performs optimally, preventing issues like ice formation or corrosion.
