High Performance Features and
Safety Precautions
The patented* XPert Bulk Powder Enclosure features the containment- enhancing
features of the XPert Balance Enclosure along with the ergonomic features of the
automatic hydraulic lift and transfer cart. The XPert Bulk Powder Enclosure
provides a revolutionary way to seal the source container to the stainless work
surface. The XPert Bulk Powder Enclosure is unique, providing unmatched
containment, safety and ergonomics all in one complete system.
High Performance Features
1.
Barrier Containment Air Foils
The containment-enhancing and aerodynamic design of the upper sash foil,
side air foils and lower Clean Sweep

air foil all prevent escape of powder
concentrations along the perimeter of the sash opening.
2.
Rear Perforated Baffle
The rear perforated baffle promotes horizontal laminar air streams through
three zones that increasingly provide more airflow at the lower work
surface. This smooth airflow minimizes the forward air roll preventing
contaminated powders from moving toward the sash opening. The
concentrated powders are primarily removed on the first pass through the
chamber. The rear perforated baffle also pivots down for ease in cleaning.
3.
Upper Dilution Air Supply
The upper dilution air supply constantly bathes the sash interior and
reduces stagnant air pockets in the upper interior of the enclosure thereby
reducing concentrated powders.
