Which process creates air pressure in a pneumatic system?

In a pneumatic system, air pressure is primarily created through mechanical compression. This process involves using a mechanical device, typically a compressor, which compresses air by reducing its volume. As the volume of the air decreases, the pressure increases according to Boyle’s law, which states that at a constant temperature, the pressure and volume of a gas are inversely proportional. By compressing the air, the system can generate sufficient pressure to perform various tasks, such as powering actuators, cylinders, and other pneumatic devices.

This process is fundamental to pneumatic systems, as it allows for controlled pressure delivery to perform work effectively. The use of mechanical means ensures that air can be stored and utilized efficiently, making it a practical approach in industrial applications.
