PowderSafe™ Type C Enclosure

PowderSafe™ Type C Enclosure

A universal enclosure built with the application and operator in mind



AirClean Systems Type C PowderSafe balance enclosure incorporates the user-friendly features and chemical fume containment capabilities of the ductless fume hood with airflow dynamics and HEPASafe features of the PowderSafe Type B. Thermally fused polypropylene makes the PowderSafe Type C enclosure perfect for powder or solvent weighing, manipulation and enclosing weighing equipment. Fitted with the AirSafe automatic safety controller, the Type C PowderSafe has an even laminar flow airstream for accurate weighing.

The entire rear wall of the enclosure is a filtration zone; a clean sweep of all particulate and gases is achieved. This design feature makes the Type C PowderSafe ideal when weighing the lightest powders or the heaviest solvents.

AirClean Systems HEPASafe filter change-out technology, incorporated into each PowderSafe Type C Powder Enclosure, allows the operator to safely and effectively change both the pre-filter and primary HEPA filter. Standard on each Type C enclosure is the AirSafe Automatic Safety Controller. The face velocity on the PowderSafe Type C 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.



  • Horizontal laminar airflow pattern
  • AirSafe™ automatic safety controller

PowderSafe™ Type C Enclosure Airflow Diagram

PowderSafe™ Type C 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
  • Waste port for weighing vessels
  • ULPA filter
  • Gas phase bonded carbon filtration
  • Contrasting base color
  • Sturdy stand with leveling feet
  • Polypropylene base cabinet
