Fume hoods are one of the most important safety equipment used to protect laboratory personnel form getting exposure to toxic gases, hazardous chemical fumes and harmful vapours generated during experiments performed inside fume hoods. (Caution: chemical fume hood may not provide protection from highly toxic i.e. LD < 50 mg/kg or highly reactive materials. This kind of operations must be carried out in a Glove box or other tightly closed system). Jay veer fume hoods are supported by properly designed fume exhaust duct system having efficient centrifugal blower. In order to compete budget and space the exhaust duct system can be clustered with more than one fume hoods too.
