Pneumatic means filled with or operated by compressed air. In general, pneumatic means related to air or wind, and pneumatics is the branch of physics that deals with the properties of air.

Is pneumatic the same as air?

The principles of pneumatics are the same as those for hydraulics, but pneumatics transmits power using a gas instead of a liquid. Compressed air is usually used, but nitrogen or other inert gases can be used for special applications. With pneumatics, air is usually pumped into a receiver using a compressor.

Do pneumatic systems use air?

A pneumatic system is a system that uses compressed air to transmit and control energy. Pneumatic systems are used extensively in various industries. Most pneumatic systems rely on a constant supply of compressed air to make them work. This is provided by an air compressor.
