Laminar Flow Box with acid-resistant extraction system and curtain

Laminar Flow Box with acid-resistant extraction system and clean room curtain

The EFBS-V series devices are used where clean room conditions are required, but where these conditions are at the same time impaired by vapours, combustion gases, etc., e.g. AAS graphite tubes, ICP/MS, and laboratory benches used for chemical analysis.

The extraction system has a maximum capacity of 1 cubic meter per minute and is continuously adjustable. The PVC strip curtain is adjusted so that its ends are flush with the device housing.


Control panel


The flow velocity can be controlled in 8 steps. The controls include the “night reduction” (eco) mode to save energy costs, and the “MAX” function to clean the workstation, parts, or equipment if applicable.

  • 8 level adjustment of the flow velocity with night reduction and flushing function
  • LCD display with selected flow velocity in m/second
  • Automatic flow adjustment with filter replacement indicator (optional)
  • LED fault indicator
  • Interior light switch on the control panel (optional)
  • Service and interval indicator, dependent on the usage period



Telescoping arm for extraction.

Arm with three-dimensional position adjustment for connection to the acid-resistant extraction system. Only in combination with the EFBS, EFBS-V and EBS series.
