Fume Cupboards - Enterprise Dynamic Flow ™

Principles of Enterprise DynamicFlow™ Fume Cupboard

The primary philosophy behind the development of the Enterprise DynamicFlow fume cupboard was to achieve high levels of containment of hazardous substances providing safe operating conditions without resorting to high air velocities. The aim was to reduce the overall operational face velocities from the customarily accepted 0.5 m/sec to 0.25 m/sec and in turn reduce the volume of supply and extract air by 50%.

The starting point for the new design was to take Premier's proven Enterprise model and, in a radical departure from previous practice, redesign the fume cupboard critical construction details. The following Computerised Fluid Dynamic (CFD) analysis diagrams (Figs 1 & 2) show how this was accomplished. The resulting innovative design features are currently the subject of a patent application.
