This station helps provide user protection by keeping powders and particulates contained during weighing procedures. The built-in HEPA filter is mounted in the upper plenum, and an exhaust collar allows connection to ductwork and a remote blower. The HEPA filter cell is 99.99% efficient on particulates 0.3µm in size. The deep interior easily accommodates large micro and analytical balances. The Clean-Sweep™ airfoil allows air to sweep the work surface for maximum containment. The perforated rear baffle promotes horizontal laminar airflow to maximize containment. The upper containment sash foil bleeds air into the enclosure to direct concentrations of contaminants away from the operator’s breathing zone. The upper dilution air supply introduces room air at the top of the sash to dilute contaminants in the upper chamber and bathe the back of the sash with clean air. Additional side-entry airfoils allow air to sweep across the interior glass surfaces to enhance containment. The airfoil’s ergonomic design provides a comfortable position for the operator’s forearms. Station requires a work surface, supporting base, remote blower, and ductwork (available separately).
