This paper presents practical experiences of savings within compressed air systems with the special attention to the compressed air end uses, particularly in pneumatic control systems. Firstly, the systematic approach to energy savings is presented. Following, various energy-saving measures have been reviewed. They encompassed system analysis and harmonization of production and consumption, minimisation of loses (leak prevention strategy, identification and quantification of leakages), possibilities for reducing pressure drop on filters, and three methods for optimization of pneumatic control: by-pass control, PWM control, and usage of exhaust air. Finally, energy conservation of a complex robotic cell with installed electric and pneumatic devices is shown.
