Flow Sciences’ Top Mount Safety Enclosure with Bag-in / Bag-out Filtration is engineered to provide a safe, stable working environment in laboratory settings. The 30” deep base accommodates larger micro and analytical balances and the gentle, non-turbulent airflow limits balance fluctuation and loss of materials. Internal plenums and mounted aerodynamic airfoils around the face opening ensure smooth, horizontal airflow pattern across the work surface. The bag-in / bag-out filter is designed for safe disposal and replacement of HEPA filter by a certified technician. In Flow Sciences’ “Filter First” design, the fan is positioned to remain contaminant-free even when working with potent powders.
