SEFA – Types of Ventilated Devices<\/span><\/h1>[vc_column_text]Laboratory fume hoods are perhaps the most widely used ventilated device.\u00a0<\/span><\/p>\n

However, the family of <\/span>ventilated devices<\/span><\/a> includes, in addition to the fume hoods, biosafety cabinets, laminar flow hoods, local exhaust ventilation and more.<\/span><\/p>\n

All ventilated devices used in a laboratory are safety devices and should be carefully examined<\/span><\/p>\n

for application and safe working practice.\u00a0<\/span><\/p>\n

Let\u2019s look at the SEFA classification of the ventilated devices.<\/span>[\/vc_column_text][vc_row_inner][vc_column_inner][vc_column_text]<\/p>\n
