Know the industry
history of oil sealed screw vacuum pump
The first oil-sealed rotary screw vacuum pump in the world was probably manufactured by Quincy Compressor in 1980. In the year 2004, the company expanded the business and built a new factory in Kunshan, China.
In 2010, the company was acquired by the Atlas Copco Group. All compressor and vacuum pump technologies of Quincy were shared with Atlas Copco since then. With this new rotary screw vacuum pump, Atlas Copco dominates the market more than one decade.
In 2019, the founder of Everblue, the most experienced chief engineer of Quincy and Atlas Copco thereafter, decided to start his own career, together with a mature R&D team. Thanks to the highly reliable technology, Everblue is developing fast and successfully today in the enormous Chinese market.

What our clients say
The pump is in running in the facility now and it’s more than our expectation. The performance is much higher than our pumps in use. No leak at all.
We buy this 7.5 kW pump to replace 11 pieces of 1.5 kW rotary vane pumps for chips packaging. Super low noise, only 30% load. I’m really very satisfied.
We used 3 rotary piston pumps for vacuum forming before. This EVS 950 is amazing. It’s smart, stable and saving power consumption more than 50% for us.
