Downdraft Anesthesia Work Station

The Downdraft Anesthesia Work Station is specifically designed to provide a small bench-mounted unit with unrestricted access for those procedures that are difficult to perform in a fume cabinet. The downflow action takes the contaminated air away from the operator and an audible alarm will alert the operator when the airflow falls to an unacceptable level.


  • No ducting or installation costs.
  • Integral lighting illuminates the work surface.
  • All mechanisms in the head are on the clean side of the filter, with the switches and electrical components being isolated from any contamination.
  • The filter clamping mechanism enables the filter to be easily located and ensures an even seal at the filter face.
  • The main filter block can be chosen from fourteen different types which include specialty filters for vapors of acids, mercury and formaldehyde.
  • Total airflow = 145 CFM
  • Work surface face velocity = 80 FPM
