Powder weighing fume hood

weighingexhaustcontainment

Product overview
Envair Technology’s Ventilated Balance Enclosure (VBE) is an enclosure for precision weighing of hazardous powders to six-decimal-place accuracy while providing high containment to protect the operator. The compact footprint offers improved accuracy and visibility compared with weighing inside a fume cupboard and reduces the risk of cross-contamination.

Airflow & containment
Air flows downward continuously through the front sash and top bypass, channeling air and any escaped powders to extraction through the worksurface and the H14 HEPA filters located below. The negative-pressure design directs airflow rearwards and down through the filters to ensure product containment and operator protection.

Key Features

• Standard widths: 600, 900 or 1200 mm; bespoke sizes available on request
• Optional granite slab for vibration control, supported on an independent frame to enable weighing to six decimal places
• Available in ducted or ductless configurations
• H14 HEPA filter included
• Fitted internal LED light as standard
• Construction options: stainless steel or powder-coated electro-galvanized steel
• Integral plug sockets to power balance and display
• Clear views into the unit from three sides to improve visibility of powder handling

Benefits
The VBE delivers higher weighing accuracy than fume cupboards, improved operator protection through H14 HEPA filtration and negative-pressure containment, and reduced facility cross-contamination risk due to a dedicated extraction and filtration path.
