G3Lab fume cupboard

Fume cupboards are an essential part of many Australian labs, but are large energy users and can be a key contributor to running costs of large laboratory buildings. In recent years two technologies have become popular in reducing fume cupboard running costs: variable air volume (VAV) technology and the automatic closing sash.

When combined, these two features can significantly reduce the cost of conditioned make-up air, due to the fume cupboard airflow being reduced to reflect the actual sash opening and the sash being closed more often. But fume cupboards with VAV airflow control and auto sash were typically a luxury item, limited to top-end manufacturers or as an add-on to basic models, limiting the number of new projects that can afford to install energy-efficient fume cupboards.

G3Lab recognised the benefits of bringing these features to a wider range of lab users and has now introduced its own fume cupboard which includes VAV and auto sash features at a lower installed cost, according to the company. The fume cupboard also uses Accuvalve technology to measure actual airflow, which makes it 100% compliant to AS2243.8.
