What is the need of filter in pneumatic system?

Typical commercial pneumatic filters will remove particles as small as 5 micrometres from the air. The filters protect pneumatic devices from damage that would be caused by these contaminants. These contaminants include lubricant particles ejected by the compressor, dirt particles, small water droplets or aerosols.
