Fume hoods and accessories represent one of the largest expenditures that a laboratory manager faces. The cost of air filtration does not end at the initial purchase price of a fume hood. Construction of ductwork and placement of utilities may be a one-time expense, however the ongoing cost of power and the increased HVAC load on the facility can be significant.
Ducted Fume Hoods
Traditional “ducted” fume hoods are connected to existing facility ductwork and pull contaminated air through the hood and direct it outside the facility and into the atmosphere. Ducted fume hoods can be filtered or unfiltered depending on the design and application.
Ductless Fume Hoods
Ductless fume hoods contain filters which clean contaminated air and recirculate it directly back into the laboratory. No additional ductwork is required to exhaust air to the outside. Ductless fume hoods provide the same filtration capabilities as ducted hoods, but are easier to install, have lower initial installation costs, can easily be moved or relocated in the laboratory and can be highly efficient.
