According to wikipedia: Compressed air can be used in or for:
pneumatics, the use of pressurized gases to do work.
Also: Pneumatic systems in fixed installations such as factories use compressed air because a sustainable supply can be made by compressing atmospheric air. The air usually has moisture removed and a small quantity of oil added at the compressor, to avoid corrosion of mechanical components and to lubricate them. see http://en.wikipedia.org/wiki/Pneumatics

does your text use also: fluid powered system? האם יש הבדל בין דרישות בטיחות לרכיבי ומערכות פניאומטיות, ולבין דרישות בטיחות עבור רכיבים ומערכות הממונעות ע"י נוזל

An engine IS a mechanical device that converts energy into mechanical motion. It can be powered by fuel (liquid, solid, gaseous), electricity, air ...

However this EN refers to auxiliary attachments that are coupled to heavy machinery such as tractors etc.

power system? Does the 'power system' in this context reffers to a mechanical device or engine?
