YOU SHOULD KNOW
Some Basic Knowledge
History of Oil Screw Vacuum Pump
1980
Quincy Compressor launched the world’s first oil-sealed rotary screw vacuum pump, later expanding to China with a new Kunshan factory in 2004.
2010
The acquisition of Quincy by Atlas Copco led to a merged technological prowess, enabling them to maintain the new market dominance for over a decade.
2019
Everblue, established by Quincy’s ex-chief engineer and a veteran R&D team, rapidly emerged as a market leader in China, outshining industry giants with superior technology.
