What Is Pneumatics?
The word Pneumatics comes from the Greek word Pneum
means wind or breathe.
Pneumatics is a section of technology that deals with the
application of pressurized gas to produce mechanical mo
Air is all around us even though we cant see or feel it.
Air presses on our bodies with a great force. We dont feethe air inside our bodies is pushing back equally hard.

History of Pneumatics Applications:
3000 B.C. - Simple Bellows used to start fire.
A.D 1602-1686 German Physicist Otto von Guericke invented a
vacuum pump.
A.D. 1754-1839 Scottish engineer William Murdoch Applied pneu
to postal services.
A.D.1826-1896 Alfred Beach experimented on pneumatic subw
A.D. 1888 John Dunlop invented tyre.
A.D.1904 First pneumatic subway in New York.

Compressor: It is a device which is used to increase the pressu
or gas by compressing it.
It is the core part of the pneumatic system.
It is required to run various pneumatic tools.

Why to use pneumatic tools?
They do not require their separate motor which makes then slighter and easier to handle.
Design and construction of these tools is simple and easy.
Free from electric shock and electric hazards.
A large variety of tools an be used on a single compressor.
Makes us able to tackle small household repairs like fixing boshoe rack. Hooking a wall painting etc.

Pneumatics VS Hydraulics:
No need of storage.
Air cannot be used at high
pressures as oil, as it is
compressible.
Can be operated at very high
speeds.
In case of failure due to fatigue or
aging the air storage tank will burst
setting projectiles of tank like
grenade.
