COBRA NX – For Rough and Medium Vacuum Applications

The COBRA NX is a series of high-performance and robust dry screw vacuum pumps for industrial applications. These vacuum generators are in use wherever gases and vapours need to be pumped reliably. The proven, completely dry screw vacuum technology allows the COBRA NX to run without operating fluids in the compression chamber.

In practice this means no contamination of the pumped medium, and no environmental emissions. In addition, no costs arise for the purchase, replacement and disposal of operating fluids. Maintenance tasks such as oil changes or filter replacement are no longer required or are reduced to a minimum.

Vacuum pumps of the COBRA NX series are robust, extremely reliable and highly efficient – and the most advanced screw vacuum pumps on the market today. They operate efficiently throughout their vacuum range, and deliver constantly high pumping speeds.

Your benefits at a glance:

  • Advanced Screw Design
  • Efficient: low energy consumption, minimal maintenance, minimized operating costs
  • Robust: high vapour and particle tolerance, self-draining
  • Compact Design

Product Overview


The Efficient Standard Solution for a Wide Range of Applications

Heat treatment
Vacuum systems with COBRA NX screw vacuum pumps combined with Busch Panda vacuum boosters provide perfect and efficient vacuum generation for heat treatment processes such as:

  • Nitriding/Nitrocarburizing
  • Annealing
  • Hardening
  • Tempering
  • Vacuum soldering

Vacuum is a key part of many coating processes, creating specific atmospheric conditions to improve surfaces and component properties. COBRA NX screw vacuum pumps are the optimal solution for coating processes as key part of a vacuum system. Examples of applications are:

  • Plasma enhanced deposition
  • Physical vapour deposition
  • Chemical vapour deposition

Vacuum drying
Vacuum drying is used to dry items rapidly at low temperatures and without thermal damage. For example, it is employed in the drying of foodstuffs in order to preserve food flavour. The high vapour tolerance of COBRA NX vacuum pumps makes them ideal for drying processes with high humidity. Examples of applications are:

  • Freeze drying
  • Cleaning/Drying of industrial parts

COBRA NX vacuum pumps are ideal for the vacuum packaging of wet products such as foodstuffs, and for the packaging of dusty materials. They are also highly suited to thermoforming or tray sealer vacuum packaging machines.

The high vapour and particle tolerance and advanced screw design of COBRA NX vacuum pumps make them ideal for rough degassing applications such as the deaeration of pastes and moist materials. COBRA NX are, for example, used in:

  • Clay degassing
  • Brick degassing

and many more!
