Bulk powder systems keep airborne particulates and fumes contained during powder transfer procedures
Systems also feature a built-in Guardian™ 1000 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 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. The variable speed built-in blower features a dynamically balanced, vibration-isolated motorized impeller and is outfitted with a 99.99% efficient HEPA filter. Systems incorporate an intrinsically safe, negative pressure design. 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 Minihelic® pressure gauge, two utility ports, and a left side-mounted waste chute. A front-mounted fluorescent lamp provides excellent visibility, and the systems operate quietly at 45–67dBA. Systems are constructed of epoxy-coated aluminum and steel. The front sash and sides are constructed of 0.6cm (1/4") thick tempered safety glass. Hinged front sash features an ergonomic 10° angle and pivots upward. The front sash has a 30.5cm (12") operating height, locks to a loading height of 71.1cm (28"), and features side wiping seals to contain contaminants. A push-button hydraulic lift mechanism raises the container to the optimal height. An electronic beam senses the location of the container and triggers the lift mechanism to automatically stop at the optimal access height.
