Ductless Laboratory Fume Hood Filtering Steps

  1.  Air can be drawn directly from the laboratory room into the fume hood, creating negative pressure, and the airflow at a stable face velocity creates a natural barrier to isolate users from the chemicals they handle.

  2.  The fan system sucks toxic and harmful fumes upward, then the airflow takes contaminations into the filtration   system. The filters can be customized based on the chemicals needs to purify.

  3.  The contaminations will be absorbed on the filter’s internal space, recirculating clean air back to room.
