Boxes for Handling Powdered Materials

Powder handling enclosures are designed to contain airborne particulates generated during weighing, dispensing and handling of powders. 

Devices included:

• Circulaire® Powder Containment Cabinet
• Circulaire® Powder Containment Booth

1. Circulaire® Powder Containment Cabinet

Technical information

• Air volume: 375–720 m³/h
• Air velocity: 0.4 m/s
• Primary filter: H14 HEPA (99.9995% at 0.3 µm)
• Exhaust filter: Optional activated carbon / HEPA
• Power consumption: 150–250 W (max.)
• Sound level: approx. 50 dB(A)

The Circulaire® Powder Containment Cabinet provides a controlled environment for accurate weighing and handling of powders. Designed for precision applications, it ensures stable airflow conditions and reliable containment, minimising the risk of exposure while supporting consistent and repeatable weighing results.

2. Circulaire® Powder Containment Booth

Technical information

• Air velocity: Adjustable up to 0.9 m/s
• Air volume: Adjustable up to 1350 m³/h
• Primary filter: H13 HEPA (99.97% at 0.3 µm)
• Power consumption: up to 960 W
• Sound level: approx. 60 dB(A)

The Powder Containment Booth is designed for handling medium to heavy powder applications where higher airflow and larger working space are required. Negative pressure and high-efficiency filtration ensure airborne particulates are captured at source, providing effective operator protection during open powder handling tasks.
