Heavy-Duty AC Compressor Assembly 200V77970-7028 for HOWO T7H TH7 TX MAX T5G Trucks

As the "heart" of the truck cab air conditioning system, it is driven by the engine belt via an electromagnetic clutch. It is responsible for compressing low-pressure gaseous refrigerant (R134a) into high-pressure, high-temperature gas and sending it to the condenser, serving as the power source for the entire refrigeration cycle. The housing is typically made of high-strength, lightweight cast aluminum, offering rapid heat dissipation and strong shock resistance. Equipped with reinforced solenoid valve coils and high-precision one-way bearings, it can withstand frequent start-stop cycles at high engine speeds, and its internal seals are heat-resistant and refrigerant corrosion-resistant, effectively preventing Freon leakage.
