Although they can be put to the same uses as fume hoods, they also provide a physical barrier for noise reduction. They make it possible to confine extensive work areas, preventing cross-contamination between different analytical techniques.
They are recommended for the evacuation of non-toxic fumes and heat from a work area in order to prevent dispersion into the laboratory atmosphere.
They are not recommended for use with toxic compounds that emit ionising radiation, concentrated acids with a high thermal load, or pathogens. They are available in standard modules of 900-1500 mm, with three configuration options: sash, hinged or sliding. They include lighting and an on-off switch on the side. From an energy consumption point of view we recommend the VAV version, which is available in variable flow and constant flow versions.
