How Ductless Laboratory Fume Hoods function in a lab

Info

Ductless Laboratory Fume Hoods should only be used in situations where the risk is extremely low and where access to the hood and the chemicals used inside are strictly regulated.

Ductless fume hoods are self-contained, filtered laboratory enclosures that eliminate dangerous fumes, vapours, and particles from the lab. They are also known as carbon-filtered enclosures or filtered fume hoods. Unlike conventional fume hoods, they require no ductwork and have relatively cheap installation costs.

It eliminates chemical odors, is less expensive, and requires less effort to install. Before choosing a ductless fume hood, there are a few crucial factors to take into account. To be certain that a ductless fume hood is an ideal option for your laboratory and your applications, carefully analyze the following four factors:

Despite the fact that ductless and filtered fume hoods come in several classes, certain hoods still have restrictions on the types of applications that can be done inside. Only light-duty or process-specific ductless fume hoods should be utilized, according to some manufacturers. A wide variety of chemicals can be employed in other filtered fume hoods, however, keep in mind that increased chemical contents will always result in shorter filter life.

This implies:

• There should only be a few different kinds of chemicals used.

• No intense heating, such as acid digestion applications, should be done in the hood.

• The recommended chemical volume should be 500 ccs or less per chemical.

• Longer periods of moderate chemical exposure should be maintained.

A typical ducted fume hood is most likely the best choice for optimal safety and practicality from an economic standpoint if your application does not fit these criteria. The application should be done in a ducted fume hood if you don't know what chemicals will be utilized in the future or if you have a very large list of compounds.

Ductless hoods are frequently fitted with filters designed for certain chemicals. For different chemical families, specific filter types maximize chemical trapping capacity; nonetheless, some chemicals cannot be properly filtered or cannot be filtered efficiently enough to make ductless hoods a financially viable choice. Acids, bases, and solvents can all be removed by filtered fume hoods using a single type of filter, however, some compound’s low molecular weight solvents cannot be removed in this way.
