PowderSafe™ Type B Enclosure

PowderSafe™ Type B Enclosure

Effectively weigh powders to seven decimal places



AirClean® Systems PowderSafe Type B enclosures usher in a new era of powder weighing and containment technology. Precise airflow control is achieved with the AirSafe automatic safety controller. AirSafe allows the operator to set the desired face velocity and then automatically maintains that setting. HEPASafe filter change technology provides a safe and effective means for replacement of both the pre-filter and primary HEPA filter.

PowderSafe™ Type B Enclosure Airflow Diagram

PowderSafe™ Type B Enclosure Airflow

  1. A
    Turbulence-free laminar flow room air enters enclosure.
  2. B
    Air is drawn in an even horizontal laminar fashion toward the rear plenum of the enclosure while being mixed with contaminated air.
  3. C
    Contaminated air enters a pre-filter and then the primary HEPA filter.
  4. D
    Air cleaned by the primary HEPA filter enters the permanent safety HEPA filter.
  5. E
    Clean air is recirculated into the room.
