Compressed air in industry

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

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.
