1.0 INTRODUCTION TO PNEUMATIC SYSTEM

A fluid power system is one that transmits and control energy using pressurized liquid
or gas. In pneumatics, this power is air. Air which is colourless, odourless and tasteless

gas consisting of approximately 78% nitrogen and 20% oxygen [1]. The remaining
2% consists of about 1% Argon and a mixture of other trace element such as helium,

hydrogen and neon.

“Air has existed since the beginning of time. Man has harnessed the power of the

wind to power many devices. Only in the last century has man used air as power
transmission medium.”.

Pneumatics came from Greek terminology, pneu mean a breath of air and matics mean
flow power. Pneumatics known as the use of compressed air to generate force that can

produce mechanical movement.

1.0.1 Examples of pneumatic control in the industry field.

i. Foods industry
ii. Industrial robotic and automation)

iii. Electronic Industry

iv. Air tools
v. Operation of bus doors

1.0.2 Advantages of Pneumatic System

i. Availability
a. As we know, air is practically available everywhere in unlimited quantity

b. and it is free sources.

ii. Transportation
a. Compressed air can be easily transported in pipe lines from one point to

another point location.

b. Its be not necessary to return the compress air reservoir.
