The PowderSafe Type B enclosure provides a controlled negative pressure HEPA-filtered environment for professionals to work with and weigh powders. The enclosure is fabricated with polypropylene, which is a chemically resistant, high mass polymer. The innate chemical resistance of polypropylene allows users to easily clean the enclosure without the worry of degradation, while the high mass construction alleviates the threat of vibration and balance disturbance during weighing.
The operator can change both the prefilter and the primary HEPA filter safely and easily while the enclosure remains under negative pressure. Furthermore, even, horizontal air distribution is provided throughout the enclosure, preventing turbulence. This laminar horizontal air movement ensures operator protection from hazardous chemical and compounds being manipulated within the enclosure. Manufacturer says it has been independently tested for containment by both SafeBridge Consultants, Inc and Triangle Certification. AirClean Systems
