Atlas Copco’s GHS range of oil-sealed rotary screw vacuum pump combines a robust oil-injected rotary screw technology with Atlas Copco’s advanced screw design.

Efficient, on-site vacuum

GV 1200 Vacuum

Oil-injected rotary screw systems are highly efficient vacuum technologies, in the operating pressure range 10 mbar(a) to 650 mbar(a). The two screw elements rotate at slow speeds, so the GHS runs at sound level from 82 dB(A). Such silent operation allows you to install the GHS close to the point of use.

Reliable performance

Reliability is a key feature of the GHS vacuum system. The technology is contract-free and thus wear-free. As an added benefit, the oil-injection technology leads to robust, trouble-free operation. Next to this advanced technology, the GHS is outfitted with reliable, oversized motors and a highly efficient oil-mist separation. The state-of-the-art coalescing filters reduce oil mist carry-over in the environment. This leads to less oil top-ups, lower running temperatures and lower motor power consumption.

Benefits of the oil-sealed rotary screw vacuum pumps

  • Match capacity to demand: the modulated valve is fitted directly to the pump inlet
  • Plug-and-play installation.
  • Space saving canopy, thanks to lift-out panels instead of swing-out doors.
  • Maximum uptime, thanks to minimal maintenance.
