Laboratory Fume Hood

Laboratory Fume Hood 

Two main types exist, ducted and recirculating (ductless). The principle is the same for both types: air is drawn in from the front (open) side of the cabinet, and either expelled outside the building or made safe through filtration and fed back into the room. 

• Protect the user from inhaling toxic gases
• Protect the product or experiment 
• Protect the environment
• Secondary functions of these devices may include explosion protection, spill containment, and other functions necessary to the work being done within the device. 

Fume hoods are generally set back against the walls and are often fitted with infills above, to cover up the exhaust ductwork. Because of their recessed shape they are generally poorly illuminated by general room lighting, so many have internal lights with vapor-proof covers. The front is a sash window, usually in glass, able to move up and down on a counterbalance mechanism.
