A method and a system for producing and supplying compressed air

摘要: In a system (1) for producing compressed air, of the type comprising an electric motor (26) driving rotary compressor (4), air is supplied directly by (4) to one or more services tools (28) without using any intermediate storage device such as receiver; demand greater lesser quantities met varying speed rotation (26), hence in response difference between supply pressure (Pr) registering at outlet and preset operating (Pu). The two pressures monitored continuously, result variable characteristic remains constantly negligible level.
