Powder Weighing Balance Enclosure Laboratory operations involving weighing, mixing and dispensing hazardous or nuisance powders can now be performed safely and economically with the Esco Powdermax 1 Powder Weighing Balance Enclosure. The enclosure’s unique design maintains balance stability to 4 decimal places without compromising containment. Designed specifically for powder containment applications, the Powdermax Enclosure employs carefully directed inward airflow at the face of the enclosure to protect the operator from exposure to hazardous powders or potent pharmaceutical compounds. The aerodynamically designed enclosure reduces airflow turbulence for maximum containment while minimizing the effect that air drafts may have on sensitive weighing balances. The enclosure design exceeds the containment requirements of ANSI/ASHRAE 110 as proven by independent type testing. All exhaust air is HEPA-filtered, removing virtually all particulate matter, before recirculation to the laboratory. Designed for Enhanced Usability and Efficiency The Powdermax 1 is designed specifically to provide the operator with a high level of usability, comfort and visibility. • A 13-degree sloped front allows easy access to the work zone, eliminating operator fatigue and increasing productivity. • Transparent 6 mm (0.2”) frameless acrylic front and sides enhance visibility and operator comfort during longer periods of operation. The self-supporting pre-tensioned hinges on the front window provide easy access during loading and start-up. • Ergonomically designed apertures for hands simultaneously provide maximum movement within the work zone while protecting the operator. The curved front edge minimizes airflow turbulence and improves user comfort. Esco Powdermax 1 Powder Weighing Balance Enclosure Model PW1-3A_ • Electronic ballast for the fluorescent lighting provides zeroflicker with increased energy efficiency, reliability and service life with a lower heat output. • Two electrical pass throughs on the back wall of the unit provide convenient access to power sources for equipment. • The spacious interior dimensions will easily accommodate large analytical balances. Enhanced Filtration System The enclosure’s unique filtration system ensures the highest level of protection for the operator. • The Powdermax 1 provides enhanced safety to laboratory personnel by drawing air across the front opening in the hood at a controlled rate, preventing the escape of powders and particulate matters into the general laboratory environment. • A unique filter mounting system eliminates bypass leaks inherent in conventional clamping systems. • The Powdermax 1 is equipped with a generously sized HEPA filter system, rated at >99.99% efficiency for 0.3 micron sized particles. • The aerodynamically designed system constructed of 1.2 mm (16 gauge) epoxy powder-coated electrogalvanized steel delivers maximum containment by ensuring airflow uniformity throughout the work chamber of the cabinet. • Since HEPA-filtered air is recirculated to the laboratory, the enclosure does not have to be connected to an extraction/ exhaust system, resulting in low operating costs and mobility. User-Friendly Control System The user-friendly Esco SentinelTM micro-processor based control system is fully configurable according to operator’s requirements and comes equipped with a number of enhanced features to

Powdermax 1 Powder Weighing Balance Enclosure Airflow Blower Exhaust HEPA Filter Unfiltered / potentially contaminated air Inflow air Room air is drawn in across the front of the The state-of-the-art baffle system ensures airflow uniformity throughout the cabinet's main chamber. Air is drawn up through the cabinet's work zone and forced through the HEPA filter (>99.99% typical efficiency for 0.3 micron sized particles). The HEPA filtered air then returns to the laboratory stripped of all airborne contaminants or is vented through the optional exhaust collar to exhaust ducting for enhanced safety....
