INTRODUCTION OF PNEUMATICS

What is pneumatic systems ?

• Pneumatic is a system that is worked using the air pressure or air flow

• pneumatic is a system that is worked using the air pressure or air flow but

  controlled using electrical devices

• pneumatic is a system that is worked using fluid
