Laboratory Systems is a recognised leader in the design, manufacture and installation of fume cupboards and associated systems. With over fifteen years of experience, our engineering team has an unrivalled breadth of technical knowledge and advice they can provide.

Laboratory Systems was the first UK company to develop and patent a high containment / low energy fume cupboard. The DynamicFlow fume cupboard offers high levels of safety whilst reducing energy cost by up to £1,000.00 per year per fume cupboard.

Whilst the safety of laboratory personnel is paramount, the amount of heated/conditioned air consumed by conventional fume cupboards is a constant area of concern to many laboratory managers. Surprisingly, fume cupboard design has changed little since the 1970s. The conventional operation specification for fume cupboard is to provide an average face velocity of 0.5 m/sec across the open sash area.

Traditionally this has been taken as a minimum and can actually range up to 0.75 m/sec in certain circumstances. Where a number of fume cupboards are grouped together the total extract volume is very high which results in a large volume of make-up air being required to balance the laboratory pressure.

Over the past 10 years, it has become standard practice to address this problem not at the fume cupboard itself but by designing sophisticated extract and air input systems, often referred to as variable air volume systems (VAV.).

These typically use complex sensing and feedback controls to monitor the instantaneous demand at each fume cupboard in order to calculate and adjust the correct volumes required. Although the VAV approach has proved successful and cost effective in many cases, it does not address the problem at source, namely the volume of air required by an individual fume cupboard to maintain the containment performance.
