PowderSafe™ Bulk Handling Enclosure

PowderSafe™ Bulk Handling Enclosure

Effective containment during bulk powder manipulations



AirClean® Systems PowderSafe Bulk Handling Enclosures provide effective control and containment of airborne particulate during manipulation and transfer of potent compounds. Designed to provide a turbulent free airflow environment, PowderSafe™ Bulk Powder Handling Enclosures move air in a horizontal pattern to maximize containment while minimizing sample loss and balance instability.

AirClean® Systems PowderSafe Bulk Handling Enclosures come complete with a sturdy stand which provides a comfortable working height of 39 inches. The bulk powder handling enclosures are available in 4-ft., 5-ft. and 6-ft. widths with a nominal depth of 36 inches.

AirClean® Systems HEPASafe filter change-out technology, incorporated into each PowderSafe Bulk Powder Handling Enclosure, allows the operator to safely and effectively change both the pre-filter and primary HEPA filter. Standard on each bulk handling enclosure is the AirSafe Automatic Safety Controller. The face velocity on the PowderSafe Bulk Handling Enclosures, as preset by the operator, is constantly monitored and maintained by the AirSafe Automatic Safety Controller. AirSafe monitors the condition of both HEPA filters and provides audible and visible alarms when filter change out is necessary.

Optional bonded carbon filtration for removal of fumes during bulk chemical handling and dispensing can be added to the PowderSafe Bulk Handling Enclosure. Bonded carbon filters can be placed in the exhaust of the enclosure to capture chemical vapors. The AirSafe Automatic Controller constantly monitors the carbon filter life and alerts the end user when filter change out is necessary.



  • AirSafe™ automatic safety controller

PowderSafe™ Bulk Handling Enclosure Airflow Diagram

PowderSafe™ Bulk Handling Enclosure Airflow

  1. A
    Air enters in an even horizontal laminar fashion.
  2. B
    Contaminated air enters and particulate is removed via electrostatic pre-filtration and HEPA filtration.
  3. C
    Particulate free air moves upward where it enters the HEPASafe™ filtration area.
  4. D
    Particulate free air passes into the bonded carbon filtration bed to remove chemical fumes and vapors.
  5. E
    Clean air is recirculated into the room.



  • Carbon filtration for liquid chemicals
