1.Cleanliness

-Air is used by a machine and is then exhausted to the atmosphere.

-no return line is necessary.

-Any leaks will be of air

2.Availability

-Air is freely available in the pneumatics.

-very easy to set up a manufacturing process.

-Simplicity of Design And Control

-Control is as easy as it is simple ON-OFF type control.

3.Reliability

-Pneumatic systems tend to have long operating lives and require very little maintenance.

-The equipment is less likely to be damaged by shock

4.Storage

-Compressed Gas can be stored, allowing the use of machines when electrical power is lost.

5.Safety

-Very small fire hazards (compared to hydraulic oil).

-Machines can be designed to be overload safe.
