Description
A0042300311 – Mercedes-Benz OE AC Compressor
The A/C compressor is the core component of the automotive air conditioning system, functioning as a pump that circulates refrigerant under high pressure. It draws in low-pressure refrigerant gas from the evaporator, compresses it into a high-pressure, high-temperature state, and pumps it into the condenser. This specific unit is a variable-displacement 6SEU16C style compressor, which utilizes a swash-plate design to adjust refrigerant flow according to cooling demand, enhancing fuel efficiency. Key specifications include a 115mm 5-groove (rib) belt pulley and compatibility with R134a refrigerant.
