A Mid-Range Solution for Everyday Lab Work

KNF LABOPORT N 820 G is a mid-range, versatile solution for a broad spectrum of lab applications, offering a flow rate of 20 l/min, an ultimate vacuum of down to 6 mbar abs., and a pressure of up to 0.1 bar g. 

Winner of Red Dot Design Award 2020

Working closely with researchers and scientists, the company launched this newly-revamped laboratory vacuum pump series with various user-centric improvements. In 2020, the Red Dot Jury honored the LABOPORT N 820 G with the internationally-acclaimed award for its modularity and usability.

Feature Highlights
  • A beautiful, streamlined surface that is easy to clean
  • Modularly expandable — separators/condensers are available individually at any time, users can now build their custom-fit vacuum system with ease
  • Straightforwardly monitor current status with the new three-color display (in operation, standby, and error)
  • High chemical resistance and excellent compatibility to most vapors and condensate
  • ATEX compliance in accordance with (Ex) II 2/-G IIB+H2 T3 (internal atmosphere only)
  • Integrated gas ballast valve and rotational speed control
  • The pump can start against the ultimate vacuum

Moreover, the new LABOPORT pump series offers a 20% – 30% reduction in footprint compared to its predecessors, further saving valuable laboratory workspace.
