PNEUMATIC Understanding the basic of pneumatic
Aditya@poltekom.ac.id
Definition • Pneumatic is a system / tools that is worked basically using the air pressure / air flow • Therefore the force / work / displacement generated based on the general law of air pressure and flow • Pneumatic is an actuator using the air pressure as their source of power
