What is the main component used to store compressed air in a pneumatic system?

The main component used to store compressed air in a pneumatic system is the air receiver tank. This device serves as a reservoir that holds compressed air, allowing the system to maintain consistent pressure and provide a steady supply of air to various tools or actuators during operation. The air receiver tank buffers demand fluctuations, ensuring that there is enough compressed air available when needed, and it can also help in trapping moisture and particulates from the compressed air before it reaches other components.

While other components listed, such as pneumatic actuators, pressure regulators, and flow control valves, play essential roles in the functioning of a pneumatic system, they do not serve the primary purpose of storing compressed air. Pneumatic actuators convert compressed air energy into mechanical motion; pressure regulators control the air pressure to ensure it remains within desired limits; and flow control valves regulate the speed and direction of air flow, but none of these components are designed specifically for the purpose of storing compressed air.
