Mercedes-Benz 30L-4-port air tank As a core component of the Actros series heavy-duty truck pneumatic system, its main function is to ensure the stable operation of the braking system and related equipment, specifically as follows:

- Store compressed air ：The 30L capacity can store a sufficient amount of compressed air to provide a continuous air source for the vehicle's braking system (such as service brakes, parking brakes), pneumatic auxiliary equipment (such as air horns, pneumatic windows), avoiding insufficient air pressure due to high instantaneous air demand.

- Stable air pressure output ：By storing compressed air, it buffers the air pressure fluctuations from the air compressor, providing stable air pressure for the braking system, ensuring uniform braking effect (such as avoiding sudden changes in braking force), and improving driving safety.

- Filter and precipitate impurities ：After the compressed air enters the air tank, the flow rate decreases, and the moisture, oil stains, and other impurities in the air will precipitate at the bottom of the tank, reducing wear and blockage of precision parts such as the brake valve and air chamber, and extending the service life of the pneumatic system.

- Adaptable to 4-port pneumatic connection ：The four connection ports correspond to different pneumatic functions (such as connecting the air compressor intake, brake chamber exhaust, air pressure sensor interface, etc.), precisely matching the pneumatic layout of the Actros series, ensuring smooth pneumatic connection, and improving system response efficiency (such as rapid air supply during braking).

In short, it is the "air source warehouse + pressure stabilization station" of the Actros series heavy-duty truck pneumatic system, ensuring that air-consuming equipment has sufficient air source, and ensuring the reliable operation of core functions such as braking through stable air pressure and impurity filtration.
