VENTILATED BALANCE ENCLOSURE

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.

Key Features

  • Designed specifically for weighing and dispensing operations requiring localized ventilation.
  • SS304 stainless-steel internal surfaces provide durability and easy cleaning.
  • Rear air-plenum/baffle arrangement helps promote uniform airflow.
  • Service-access arrangement facilitates filter and fan maintenance.
  • Airflow monitoring and alarm provisions can be integrated.
  • Ergonomic work height provides a comfortable and clear working area for balance operation.
  • Custom dimensions, exhaust connections, control configurations, and material options can be provided according to an approved URS.

Applications

The VBE is suitable for:

  • Pharmaceutical API and powder handling
  • Laboratory weighing
  • Pharmaceutical powder dispensing
  • Controlled handling of dry powders where localized containment is required
  • 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.
