Original Press Release:
NEW XPert(TM) Filtered Balance System Provides User Protection During Weighing Procedures
XPert Filtered Balance Systems provide user protection during weighing procedures by keeping powders and particulates frequently found in pharmaceutical, dry chemical, mold and asbestos weighing operations contained and away from the operator. The interior depth of 23" accommodates large micro and analytical balances. Containment-enhancing features include the patented* Clean-Sweep(TM) air foil that allows air to sweep the work surface, the upper containment sash foil to bleed air into the enclosure to direct concentrations of contaminants away from the users' breathing zone; and a zone-perforated rear baffle that creates horizontal laminar airflow. A true bag-in/bag-out filter disposal system allows the HEPA filter to be safely removed and replaced by a certified technician.
The frame is of sturdy glacier white and gray, dry powder epoxy-coated aluminum with a steel rear panel and baffle. Tempered safety glass sash, sides and top offer excellent visibility and provide better fire, scratch and corrosion resistance than acrylic. The ergonomic 20° angled sash allows a closer view, reduces glare and provides a more comfortable operating position than vertical sashes.
The built-in blower and exhaust HEPA filter mounted in the upper plenum take up less space than a separate exhauster and filter housing would require, while isolation supports minimize blower vibration. Since HEPA filtered air is returned to the laboratory, these enclosures have the added benefits of low installation costs, portability and energy savings as outside ducting is not required. Enclosures are available in 2', 3' and 4' widths.
