Are there any energy-efficient options available for fume cupboards?

Yes, energy-efficient options are available for fume cupboards. Some models incorporate Variable Air Volume (VAV) systems, which adjust the airflow based on the sash height, resulting in the reduction of extracted conditioned air whilst the fume cupboard sash is in the closed position. Additionally, the use of energy-efficient fans, LED lighting, and smart control systems can further enhance the energy efficiency of fume cupboards.
