Class IIA BSC - E Series

Metisafe® biological safety cabinets recirculate 70% (-/+5%) of the device’s total air. After passing through the main HEPA/ULPA filter, the clean air flows down to the work chamber. The 30% (-/+5%) of the total air is exhausted out of the cabin after passing through the exhaust HEPA filter at the top of the device. The indoor environment’s intaken air is passed through the air grills in the front section of the workbench and directed to the fan unit. Those air barriers prevent the reach of dirty indoor air into the workbench. Both intaken and recirculated total air inside the device is collected in the fan section. Then it passes through the pre-filter (optional), main HEPA filter and laminarizator, and protects the work material by providing ISO-5 cleanliness class laminar airflow. The primary air barrier occurs in the work chamber and the negative plenum structure surrounding it. The air in the cabin is prevented from reaching the user, including possible accidents,and a zero leakage work station is provided.
