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

The AirSafe automatic safety controller, a standard feature on all PowderSafe enclosures, monitors and maintains proper face velocity so accurate balance readings can be ensured without turbulence or vibration. AirSafe also monitors HEPA filtration and will alert the end user if filter change is necessary. This advanced technology allows PowderSafe to be completely self-contained and self-monitored, eliminating the need for external filter boxes, ductwork, filter sampling ports or other cumbersome parts.
