Product Overview
The Ventilated Balance Enclosure (VBE) is designed for controlled weighing, dispensing, and handling of pharmaceutical powders. It provides a localized, controlled working environment around the weighing operation through negative-pressure ventilation, HEPA filtration, and controlled exhaust.

- Balance weighing and preparation activities in controlled environments
Engineering & Compliance
Final airflow performance, fan duty, filter grade, pressure drop, noise level, electrical load and exhaust configuration should be confirmed against the approved URS, process risk assessment, site conditions and applicable project standards before fabrication. The brochure identifies recommended/typical values as design-basis values rather than guaranteed performance claims.
