Circulaire® Hybrid Fume Cupboard

The highly energy efficient Circulaire® Hybrid Fume Cupboard features Environmentally Responsible and Sustainable Active Eco Technology and Partial Airflow Recirculation. 

Hybrid Recirculating + Ducted Fume Cupboard Technology exhausts clean air to the outside atmosphere and ensures that, compared to a conventional fume cupboard, the volume of exhaust air and the energy used are reduced to contribute to a greener environment and make it a sustainable choice for laboratories and research facilities.

MonSci-Icons-Recirc Tech

Lower Air Consumption means up to 60% less outgoing air than a conventional Fume Cupboard.

MonSci-Icons-Active Eco

Saves Energy and Operating Costs by reducing Power Output, Lighting and Fan Speeds without compromising safety.

Recirculating + Ducted Fume Cupboard Technology cuts emissions by exhausting clean air to the outside atmosphere.


Operator protection is provided through filters specified to your requirements and application. 

Our Hybrid Fume Cupboard combines the best features of traditional fume hoods with advanced filtration technology setting new standards for user protection and environmental responsibility to save on energy, resource and operating costs.


The inflow air is drawn in from the laboratory through the front aperture, mixing with the contaminated air from the working chamber before being drawn through air intake grilles on the work surface into the Activated Carbon/HEPA Filters*. The advanced multi-stage filter options ensure superior removal efficiency, making it suitable for diverse chemical processes and experiments.

Cleaned and free of contaminants, the airflow is then guided through internal ventilation where it is divided so just 40% is extracted to the duct extract system.

The remaining 60% is recirculated back into the working chamber creating an air-curtain across the front aperture to provide containment and operator safety. This method differs to traditional fume cabinets which rely purely on inflow velocity for protection.

Vitally, this green process results in a 60% decrease in extraction of conditioned laboratory air that with conventional ducted fume cabinets would be lost to atmosphere.

An additional key benefit of our Hybrid Technology, in comparison to ducted systems, is the extracted air is clean and filtered. The contaminants are removed directly at the source without contaminating the building exhaust air.

Intelligent airflow management technology optimises air circulation to reduce energy consumption while maintaining constant air quality.

*Various Options for Carbon / HEPA Combinations are available.
