The workspace is swept by laminar airflow, guaranteeing clean air free of any particles likely to contaminate the products handled. A high-efficiency HEPA H14 filter removes particles before the air is extracted into the laboratory.

The safety cabinet is equipped with a double ventilation system – supply and exhaust – which guarantees a stable and constant air barrier, regardless of any filter clogging.

The air flow enters through the opening in the safety cabinet front window. All external particles are drawn through the air barrier to avoid contaminating the handling. This air flow passes under the work surface and up to the HEPA H14 filters.

The laminar airflow velocity is 0.40 m/s.

Part of the flow is redirected to the extraction filter (around 35%) for release into the laboratory. The other part of the flow (around 70%) passes through the air flow filter and is then released into the handling chamber, creating a laminar flow.

This class 100 – ISO5 air flow ensures protection of the handling against contaminants in ambient air, in compliance with European standard EN 12469-2000.
