Power, instrumentation, process and breathing air
The quality of compressed air is often characterized as
- Power air - used for tools in plant and workshops
- Instrument air - used in pneumatic process control systems, laboratories, paint spraying and climate control systems
- Process air - used in production processes, pharmaceutical and food processes
- Breathing air - used in hospital air systems, diving, cleaning of breathing equipment
Power Air
Power air quality is used for pneumatic tools in plant and workshops.
- Filtered separator is normally required
- Refrigerated compressed air dryer and particulate filter may be required where sir tools, sand blasting and pneumatic control components are used.
Instrument Air
Instrument air quality is used in pneumatic process control systems, laboratories, powder coating, paint spraying, climate control systems, packing machines etc.
- Refrigerated compressed air dryer and oil removal filter required
Process Air
Process air quality is used in production processes, chemical, pharmaceutical and food processes and laboratories.
- Refrigerated compressed air dryer, oil removal filter and oil vapor absorber may be required
- For outdoor lines in cold climate low dew point desiccant dryer and particulate filter may be required
Breathing Air
Breath air quality is used in hospital air systems, diving, cleaning of breathing equipment.
- aftercooler, coarse pre-filter, and auto draining water trap required
- suitable in-line sorbent beds and filters required
