This enclosure is ideal for procedures such as nanoparticle manipulation and dry powder chemical handling. It can help to keep hazardous powders and particulates contained. The enclosure pulls room air in from the front, and allows it to flow to the baffle, and finally through a ULPA exhaust filter (99.999% efficient on particles 0.12 micron in size) before returning to the laboratory or cleanroom. The ULPA filter is top-accessible for leak scanning of entire surface. Enclosure features a deep interior, Guardian™ airflow monitor, true bag-in/bag-out filter disposal system, built-in blower, ergonomic air foil with aerodynamic Clean-Sweep™ opening that enhances airflow, upper dilution air supply, upper containment sash foil, zone-perforated rear baffle, and pressure gauge for monitoring filter loading. Type 304 stainless steel interior sides, removable baffle, removable air foil, and integral work surface are easy to wipe down and clean. Requires a supporting base (not included).
