The Circulaire range of filtration fume cabinets are designed to provide operator and environmental protection. The cabinet provides an inflow of air >0.5m/sec through the working aperture to provide operator protection.
The contaminated air is then passed through electrostatically charged pre-filters to remove particulate and then through Activated Carbon main filters to remove chemical contaminates before exhausting the air back to the laboratory. An additional carbon or HEPA exhaust safety filter may be fitted if required.
When installed the cabinet complies fully with international standards including BS7989:2001 for filtration fume cupboards.
