A typical compressed air system includes:

• Compressor to generate compressed air
• Air receiver tank to store air and stabilize pressure
• Air dryer to remove moisture
• Air filters to remove particles and oil
• Air regulator to set the correct pressure
• Air lubricator to add lubrication when required
• Air piping to distribute air throughout the system
• Control and monitoring system to track pressure, temperature, humidity and dew point
• Safety valves for overpressure protection
• Drain valves to remove condensate

Some systems may include additional or fewer components depending on the application.
