2Properties of Compressed Air
- Availability
- Easily stored in large volumes
- Simplicity in design and control
- Provides linear and rotary movement
- Low system cost due to low component cost
3Properties of Compressed Air
- Components have long working life resulting in
longer system reliability - Environmentally friendly
- Safety issues are minimized e.g.. Fire hazards
unaffected by overloads (actuators stall or slip) - Pneumatic actuators in a system do not produce
heat (except for friction)

8Air Receiver
A pressure Vessel (Tank) normally made of metal
and installed either horizontally or vertically.
This vessel provides a volume of air to be
utilized by the system and reduced the loading
and unloading of the compressor.

9Air Treatment
All atmospheric air carries both moisture and dust
Inlet Filter
- Used to remove large particle dirt from
- entering the system.
- Used to prevent excessive
- wear of cylinder, piston rings and other moving
parts in the initial stage of the system
10Air Dryer
Compressed air cannot hold the same amount of
moisture as non compressed air. Once the air is
compressed, some of the moisture condenses in the
tank and is removed through a drain valve. The
remaining moisture will rust internal components
of the system and must be removed. One way this
is done by sending the air through an air
conditioned chamber which will condense more of
the moisture which is present.
