Compressed air, a major source of industrial energy, is being used increasingly in both the manufacturing and process industries where its distinct advantages of cleanliness, flexibility, safety and economy of use, compared with other energy sources, are fully exploited.
Modern process equipment, pneumatic controls and instrumentation, however, demand a supply of clean, uncontaminated air and this has necessitated the development in recent years of more advanced designs of compressors and ancillary equipment.
Maintenance of the cleanliness of this air, from source right up to the point of use is obviously essential. Hence air mains and branch lines are also required to be of an advanced design.
