PowderSafe Type B enclosures help protect workers from hazardous chemicals

HepaSafe technology allows the operator to change both the prefilter and the primary HEPA filter while the enclosure remains under negative pressure

The PowderSafe Type B enclosures from AirClean Systems based in Raleigh, NC in the US, provide a controlled negative pressure HEPA-filtered environment for professionals to work with and weigh powders.

The enclosures are made from polypropylene, which is chemically resistant and allows users to clean them without the worry of degradation, while their high mass construction alleviates the threat of vibration and balance disturbance during weighing.

Exclusive to PowderSafe enclosures, HepaSafe technology allows the operator to 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 protecting operators from hazardous chemicals and compounds being manipulated within the enclosure.

The AirSafe automatic safety controller, a standard feature on all PowderSafe enclosures, monitors and maintains proper face velocity so that accurate balance readings can be ensured without turbulence or vibration.

AirSafe also monitors HEPA filtration and will alert the end user if a filter change is necessary. This allows PowderSafe to be self-contained and self-monitored, eliminating the need for external filter boxes, ductwork, filter sampling ports, or other cumbersome parts.

SafeBridge Consultants and Triangle Certification have both independently tested the PowderSafe for containment.
