Jinqu specializes in producing mufflers, SCR exhaust gas aftertreatment systems, and air reservoirs

The functions and applications of the 4-hole aluminum alloy air reservoir for trailers mainly include the following:
- Storing compressed air : Provides an air supply for the trailer's braking system, horn system, and more. When the driver activates the brakes, the high-pressure air stored in the air reservoir is quickly delivered to the brake wheel cylinders, enabling the braking function.
- Stable atmospheric pressure :The compressed air pumped by the air compressor has unstable pressure. The air receiver tank allows this fluctuating air to remain inside temporarily, before steadily releasing stable compressed air—ensuring that systems like the braking system can operate reliably.
- Filtering impurities and moisture: Compressed air typically contains impurities such as moisture, dust, and oil. The air receiver tank allows the air to briefly linger inside, where water molecules, along with heavier particles like dust and oil, settle at the bottom of the tank—effectively filtering the air and protecting the pipelines and valves from corrosion.
- Cooling down : When outside air is drawn into the air compressor and compressed, it generates a certain amount of heat. The air receiver tank can then cool down the compressed air, allowing the stored air to occupy a larger volume while making it easier for moisture to settle out.
- Release the remaining pressure : When the vehicle is stationary or the braking system does not require operation, the air reservoir can release excess compressed air into the atmosphere via its exhaust valve, ensuring stable and reliable performance.
In terms of application The 4-hole aluminum alloy air reservoir is primarily used in various commercial vehicles such as semi-trailers and full trailers. These vehicles rely on reliable air supply for their braking systems, air suspension adjustment systems, and more. The 4-hole aluminum alloy design offers advantages like lightweight construction, excellent corrosion resistance, and superior airtightness. Its multiple port configurations allow for convenient connections to different air lines, easily meeting the complex pneumatic system requirements of trailers—such as simultaneously supplying compressed air to brake wheel cylinders and air suspension airbags.
