| Resumen |
The operation and limitations of conventional fume cupboards are described. These criteria (high cost of laboratory air, reduction of airflow) were used as basic parameters for a computer-assisted design programme. The outcome was the development of a new model of laboratory fume cupboard with a modified airflow system (2 vertical vortexes moving in opposite rotational directions and flowing upwards). This new design underwent extensive testing: air velocity profiles in the working aperture, gas dwell time in the hood, interference factor of the sliding window when left open. One of the advantages of this laboratory fume cupboard is the virtually total separation of laboratory air and fume - cupboard air. |
