Downflow Booths provide containment by utilizing high velocity air to capture airborne dust particles. Downflow Booths are versatile devices that can:

  • Be used to control exposure risk to hazardous materials for a wide variety of equipment and processes.

  • When used correctly, provide Operator Exposure Levels (OEL's) ≤100 micrograms/meter3 over an 8 hour Time Weighted Average (TWA).

  • Enhance cGMP practices.

Key Features

  • Modular, easy-to-clean rigid design with minimal joints.

  • Single, Two-Stage or Three-Stage HEPA/ULPA filtration can be accommodated.

  • Removable bulkhead panels enable access to fine dust filter for service from inside the booth.

  • Re-circulatory Airflow or Single Pass Airflow if solvent or hazardous fumes are present in the process (may also require explosion proof electricals).

  • Cooling Coils can be fitted to offset heat gains in re-circulatory airflow systems.

  • HEPA/ULPA gel-seal downflow filters are replaceable from within the booth. Gel-seal is more reliable than conventional gasketed seals.

  • Voltage-compensating blower(s) ensure stable airflow.

  • Magnehelic gauges provide convenient and reliable means for monitoring booth airflow.

  • Booths ship knocked-down for site assembly.

  • Compact ceiling and rear plenums maximize usable work area while minimizing floor space.

  • IQ/OQ protocols available.

  • Energy-efficient tear-drop light fittings minimize airflow disruption.

  • Comprehensive factory and site acceptance tests include: filter integrity, particle count (air cleanliness), downflow velocity and uniformity, exhaust velocity/volume, containment zone verification, noise level, light intensity, temperature rise and electrical safety.

  • Containment performance verified according to the ISPE Good Practice Guide, Assessing the Particulate Containment Performance of Pharmaceutical Equipment.
