Fume Cupboard/Hood

A Guide to Laboratory Fume Hood Types

A fume hood (fume cupboard) is a type of local ventilation device that is designed to limit exposure to hazardous or toxic fumes, vapors or dusts.

  • protect the user from inhaling toxic gases (fume hoods, biosafety cabinets, glove boxes)
  • protect the product or experiment (biosafety cabinets, glove boxes)
  • protect the environment (recirculating fume hoods, certain biosafety cabinets, and any other type when fitted with appropriate filters in the exhaust airstream)


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.


Fume hoods are generally available in few different widths: 900 mm, 1200 mm, 1500 mm, 1800 mm.


Most fume hoods for industrial purposes are ducted. A large variety of ducted fume hoods exist. In most designs, conditioned (i.e. heated or cooled) air is drawn from the lab space into the fume hood and then dispersed via ducts into the outside atmosphere.


Below is few types of DUCTED Fume hood in the market.

1) General Fume Hood 

2) Perchloric Acid Fume Hood

3) Distillation Fume Hood

4) Floor Mouted Fume Hood

5) Radioisotope Fume Hood
