Circulaire® Recirculating Fume Cupboard + Airflow Display
Filtration Fume Cupboards can be installed anywhere within your workspace and, thanks to our advanced carbon filtration technology, pollutants produced during chemical handling are captured and absorbed at source, removing the requirement for ducting to an external environment.
The non-ducted fume cabinet does not bare the high costs of installation, maintenance and operation of exhausting conditioned air, instead, the air is cleaned before being safely recirculated back into the working environment.
Recirculating Fume CabinetsIncreased Safety Performance
Our range of Single Operator Recirculating Filtration Fume Hoods are the ideal solution for laboratory workspaces where the installation of externally vented duct systems can be problematic. In working environments where a mobile solution is required, the units can be easily relocated to allow laboratories to be reconfigured.
We offer Activated Carbon, for Chemical Filtration, HEPA/ULPA Filters, for Particulate, or a combination of both to suit your protection requirements.
Recirculating clean air back into your laboratory or working environment ensures that Ductless Fume Cupboard solutions are more environmentally friendly than a Ducted option, and the environmental impact of exhausting fumes to the outside atmosphere.
