Which mechanism generates air pressure in a pneumatic system?

Which mechanism generates air pressure in a pneumatic system?

• A. Mechanical compression
• B. Electrical energy
• C. Hydraulic pressure
• D. Chemical reaction

Answer: (A)

Air pressure in a pneumatic system comes from mechanically compressing air. A compressor uses mechanical energy to push air into a smaller volume, which makes the air molecules collide more and increases pressure. The result is stored compressed air that can be released to power actuators. Electrical energy typically powers the compressor, but the actual creation of pressure is the result of the compression process. Hydraulic pressure and chemical reactions aren’t how pneumatic systems generate air pressure.
