 INTRODUCTION

This article is an update of the text written by François POYET. Part of the text has been retained.

Compressed air is increasingly used in industry and the service sector, thanks to its flexibility of application. Economic imperatives are prompting users to better anticipate production costs in order to control energy and maintenance expenditure.

The appearance on the market of new compression and treatment equipment, the constraints imposed by quality standards and respect for the environment have led decision-makers to consider compressed air as an energy in its own right, and to entrust its production to specialists capable of managing all these parameters.

As the use of compressed air expands, manufacturers are installing compressed air plants and distribution networks in their factories and on their construction sites.

Note :

This article does not deal with :

  • very low-pressure compressed air (p < 2 mbar): ventilation, air conditioning;

  • pneumatic conveying (see our articles on Document handling [A 9 336] and Pneumatic handling of bulk goods [A 9 304][A 9 303][A 9 302][A 9 301][A 9 300] ;

  • air cushions [B 1 190] ;

  • air at absolute pressures below 1 bar: vacuum technology (see the articles Vacuum pumps and Main industrial applications [BM 4 120] in this treatise;

  • combustion air blowing in metallurgy (blast furnaces, converters, etc.), in the chemical industry (reactors, etc.), in nuclear reactors, in heat engines (supercharging);

  • aerodynamic wind tunnels.
