In a pneumatic system, compressed air is supplied through which type of line?

In a pneumatic system, compressed air is supplied through a supply line. This line is specifically designed to transport compressed air from the source, such as a compressor, to various components within the system, such as cylinders, valves, and actuators. The primary role of the supply line is to ensure that a consistent and controlled flow of compressed air is available for the operation of machinery and equipment that rely on pneumatic power.

The supply line is crucial because it maintains the pressure and flow necessary for the pneumatic components to function efficiently. In contrast, return lines are utilized for the return of air or fluid back to a reservoir or to complete the circuit, while exhaust lines are designed to vent excess air from the system, and drain lines are typically used for removing moisture or contaminants. Understanding the role of each type of line helps in effectively designing and maintaining a pneumatic system.
