Enhancing Laboratory Safety with Energy Efficient VAV Systems in Fume Hoods

by | Apr 12, 2024 | 0 comments


Air quality within a laboratory significantly impacts safety, especially when handling hazardous chemicals that emit dangerous vapors. Automated VAV systems in fume hoods are essential for maintaining a safe working environment. This article explores how these systems function to enhance laboratory safety.

The Importance of VAV Systems in Laboratories

Consistent monitoring of air quality in laboratories where fume hoods are used is crucial. It ensures that harmful chemicals are efficiently vented and that the air within the lab remains safe for personnel. Automated monitoring systems provide continuous surveillance without the need for manual intervention, increasing the reliability of safety measures.

Features of Automated VAV Systems

  1. Airflow Control Systems: Modern fume hoods often include sophisticated airflow control systems like Variable Air Volume (VAV) systems. These systems adjust the air volume based on the sash height and the operations performed, minimizing energy usage while maximizing safety.
  2. Real-Time Monitoring: These systems provide continuous feedback on the concentration of various chemicals in the air, ensuring that they stay within safe limits.
  3. Integration with Ventilation Systems: Automated systems can be integrated with the lab’s HVAC system, adjusting ventilation rates based on the detected air quality to optimize energy use and maintain safety.
  4. Energy Saving: VAV systems saves about 30-40 % energy
  5. Alerts and Notifications: In the event of air quality deteriorating beyond safe thresholds, the system automatically alerts laboratory personnel and initiates emergency ventilation procedures.

LabGuard’s Role in VAV Systems

LabGuard integrates cutting-edge VAV systems into the fume hoods, providing laboratories with:
