ATEX (EX) Rated and Certified Filtration Fume Cabinet

The Circulaire 1100EX and 1400EX are both ATEX Zone 1/T4 type filtration fume cabinets. The cabinet is intended to deliver operator and environmental protection. The cabinet provides an inflow of air >0.5m/sec through the working aperture to give operator protection. The contaminated air is passed through pre-filters to remove gross particulate and then through carbon main filters to remove chemical contaminates. Finally, the air passes through a HEPA exhaust filter for fine particulate removal before being discharged back to the laboratory. All electrical components are rated for Zone 1/T4 use. The airflow is constantly monitored with a vane anemometer attached to the right side of the cabinet to supply a visual indication of face velocity. The cabinets do not require connection to an external ventilation system and can be fitted with carbon filters for fume containment, HEPA filters for filtration of particulate or both if required. The system is presented in two sizes, 1100mm wide and 1400mm.
