Circulaire® Hybrid Fume Cupboard Monmouth Features & Benefits - Recirc. + Ducted Combo-Tech ■ Environmental Sustainability - Carbon + HEPA Multi-Stage - Auto-Airflow Compensation - Energy Efficient - Touchscreen Interface Combining Safety & Sustainability Solution Operation The Circulaire® Hybrid Fume Cupboard sets the standard for environmentally responsible and sustainable choices in laboratory and research facilities. Our green hybrid process results in a 60% decrease in extraction of conditioned air that with ducted fume cupboards would be lost to atmosphere. Inflow air is drawn in through the front aperture, mixing with contaminated air from the working chamber, before being drawn into the multi-stage activated carbon and HEPA filteration system. Clean and without contaminating the building exhaust air, airflow is guided through internal ventilation where it is divided. 40% is extracted to the duct system and the remaining 60% is recirculated back into the working chamber to provide containment and operator safety. Total Airflow Recirculated Airflow Exhausted Airflow Filter Power Consumption Sound Level Activated Carbon, H14 HEPA or Activated Carbon/HEPA Combination 1.8 kw (Max.)
