Representing a quantum leap forward in rough vacuum, the new GHS 350-900 VSD+ range promises customer benefits including average energy savings of 50% compared with conventional oil-sealed and dry vane vacuum pumps, as well as best in class noise levels and oil retention. Dirk Ville, General Manager of Atlas Copco Compressors UK said: “With clear synergies between compressed air and vacuum, which represent the ‘Yin’ and ‘Yang’ of air movement, Atlas Copco has been able to use its advanced compressor technology experience to design the GHS VSD+, leading to a breakthrough in energy efficiency, capable of dramatically reducing UK manufacturers’ lifecycle costs. Approximately three-quarters of companies who use rough vacuum require oil-injected pumps, which are traditionally fixed-speed, so the potential for energy savings across UK industry is massive.” The GHS 350-900 VSD+ range, generating nominal displacement of up to 900m3/h, incorporates state-of-the-art VSD technology that enables users to precisely adapt their vacuum generation requirements to match the demands of their process. Coupled with an innovative motor design and inlet control valve, the new range sets new standards for energy efficiency in rough vacuum pumps, leading to a dramatic reduction in total cost of ownership. Other compelling benefits depend on the application, including increased production for food packaging lines.
