SHACMAN Cab A/C System Receiver-Drier Assembly DZ13241821201
It serves to absorb trace amounts of moisture and filter out particulate impurities within the air conditioning piping, while also acting as a temporary buffer reservoir for liquefied refrigerant to prevent compressor damage caused by "liquid slugging."
It is recommended that heavy-duty trucks undergo preventive replacement every two years or every 100,000 to 150,000 kilometers (or after two consecutive summers of high-temperature, heavy-load operation).
