Bulk powder stations are designed to protect the user from airborne particulates and fumes generated during powder transfer operations Systems also feature a built-in Guardian 0 digital airflow monitor. If the face velocity falls below the setpoint for more than six seconds, an audible alarm sounds and a red light glows. The alarm can be muted. Airflow monitor features an LCD display of actual face velocity and an RS-232 port. Retaining rings are constructed of Type 304 stainless steel. One retaining ring is required; it should be slightly larger than the diameter of source container and a minimum of 5.1cm (2") smaller than the inner bag diameter. Polyethylene safety sleeves are fastened with a retaining band to the outside of the source container and access opening to help contain powders for easy clean up. The access opening cover provides a solid work surface. An extra transfer caddy is available to provide for easier material handling. Optional utility shelf kit has three epoxy-coated steel shelves. An ergonomic airfoil with Clean-Sweep openings enhances airflow while a zone-perforated rear baffle creates horizontal laminar airflow to maximize containment. Systems feature large interior dimensions to accommodate large balances and equipment. Systems are equipped with upper dilution air supplies, upper containment sash foils, an upper diffuser screen, side-entry airfoils, a true bag-in/bag-out filter disposal system, a 99.99% efficient HEPA filter, and a Minihelic pressure gauge. A front-mounted fluorescent lamp provides excellent visibility. Systems are constructed of epoxy-coated aluminum and steel and feature a 25.6cm (/32") I.D. exhaust collar, two utility ports, a left side-mounted waste chute, and side wiping seals to contain contaminants. The front sash and sides are constructed of 0.6cm (1/4") thick tempered safety glass. Hinged front sash features an ergonomic angle and pivots upward. The front sash has a 30.5cm (12") operating height and
