FAW Jiefang Pneumatic Brake System Parts Air Compressor Assembly 3509010B81D 

The 3509010B81D Air Compressor Assembly is an important component of the heavy-duty truck pneumatic system, providing the compressed-air source required for the vehicle's air brake system and other air-operated functions. The compressor is mechanically driven by the engine and converts atmospheric air into pressurized air, which is subsequently processed by the air dryer and stored in the vehicle's air reservoirs. From the storage circuit, compressed air is distributed to the brake master valve, relay valves, brake chambers, trailer control circuit, and other pneumatic components according to the vehicle configuration. Because the air compressor directly supplies the pneumatic circuit, its compression efficiency and air delivery capacity have a direct relationship with the vehicle's ability to maintain the required operating air pressure during repeated braking and other air-consuming operations. For heavy-duty trucks operating in long-distance freight, construction, logistics, and high-load transportation, the air compressor works continuously whenever the pneumatic system requires additional air pressure. The 3509010B81D complete assembly is intended for replacement and maintenance of compatible truck pneumatic systems. When selecting this component, buyers should verify the part number, truck brand and model, engine model, compressor mounting position, drive connection, air inlet and outlet arrangement, and pressure specification against the original unit. Since publicly available technical information for this specific part number is limited, it is preferable to confirm the original sample or vehicle VIN/parts catalog before quoting exact dimensions, weight, or model compatibility.
