1. Pneumatic System

2.  The Pneumatics and Hydraulics is the main
elements in Fluid Power. (Kuasa bendalir)
 What is Fluid Power?
 Fluid Power is a method to transmit power from one
location to the other by using of confined fluid, which is
in the form of liquid and gas.
 Kuasa bendalir adalah satu kaedah untuk menghantar
kuasa dari satu tempat ke tempat yang lain dengan
menggunakan bendalir terkepung, dalam bentuk cecair
atau gas.
 Hydraulic is a transmission of power (penghantaran
kuasa) through liquid.
 Pneumatic is a transmission of power through gas or
air.

9. What is Pneumatic?
 Greek Nomenclature
 Pneu – air
 Matic – power
 Pneumatic System
 A system that powered by compress air to move actuator.
 A system that uses air to power something

10. Usage of Pneumatic
 Electronic industries
 Food industries
 Robotic
 Air is also used to power drills, sanders, grinders,
and the like at garages and car body shops.

11. Advantages
 Can transfer power even in long distance.
 No effect on higher temperature
 Flexibility in control
 Very fast response and movement
 No air return
 Clean working area
 Easy to setup (build circuit)
 Very cheap (air source)

12. Disadvantages
 Requires careful preparation to get compressed air
 Noisy
 Low maintenance cost but high preparation cost
 Limited force
 No speed consistency due to compress able air
 Lot of hoses to build circuit
