Ductless Fume Hoods

Cabinet Filtration System •

The inflow moves from the ambient environment into the work zone through the hood front opening with an average velocity of 0.4 m/s or 80 fpm • Negative pressure is maintained within the main chamber of the hood to ensure that no chemical fumes or vapors escape the work zone • Air is taken through the pre-filter and activated carbon mounted in the interior of the hood. The carbon filter removes all fumes from the exhaust air stream and filtered clean air is exhausted directly back to the room.
