AC Compressors are essential components of a vehicle's HVAC system, responsible for circulating refrigerant to produce cool air within the passenger compartment. Located within the engine bay, these pumps compress refrigerant gas, increasing its temperature and pressure before it flows to the condenser. Proper compressor function is vital for efficient air conditioning, ensuring driver and passenger comfort. These compressors are utilized in passenger cars and commercial vehicles alike, and often require specialized oil and expansion devices for optimal performance. Examples in this HVAC > AC Compressor category include units from MAHLE (MPN 70817545, 72440561), MAN (MPN 81.61930-0042) and for Volvo Trucks and Scania (MPN 2760241).
