Many people are familiar with their stove hoods and they are well aware of the benefits of having them. Being able to expel smoke and steam through a vent can come in very handy when you’re cooking and don’t want the fire alarms to go off. However, very few people take that extra step to include a ventilation system of the same type and apply it to business. Some companies, such as metal refineries, need these types of systems to ensure the safety of their employees and if they don’t have a system to ventilate noxious gasses and other fumes from a work area they can be held liable for any damages that may be caused to a person.

Fortunately, many businesses are well aware of the dangers involved in their particular industry and strive to make the work place as clean and healthy as possible. Even old automotive painting booths have been retrofitted with fume hoods to expel excess paint particles. Most of these ventilation systems, unlike your stove hood, are hooked into a purifier of some type that helps to remove the dangerous particles from the air before it is expelled into the atmosphere.

There are several great manufacturers of these much needed ventilation hoods that offer a wide variety of products to meet individual needs. In many cases companies will also warranty and install their product with the proper system requirements for little to no extra cost. With the several styles and multiple manufacturers to choose from, there is sure to be a fume hood option that fits your businesses particular needs while accommodating even smaller budget companies.

When it comes to laboratory fume hoods, the selection on the market is quite impressive. No matter if you are looking for a sophisticated hood system or a specialized ventilation equipment, you can easily purchase it. A fume hood is the perfect ventilation device for numerous purposes. In fact, such a device should not be missing from a laboratory.

A fume hood is a ventilation machine specially designed to limit the exposure to hazardous or toxic fumes, vapors or dusts. This actually is a large piece of equipment, so you need to make sure you have enough space to accommodate it.


Nowadays, there are two types of laboratory fume hoods available in sale. They both function on the same principle.

  1. Ducted fume hoods draw the air from the room and expel it outside the building.
  2. Recirculating fume hoods draw the air and filtrate it to make it safe, before being flown back in the room.

Why to use fume hoods?

Fume hoods are a must in laboratories. They can:

  • Protect the user;
  • Protect the product or experiment performed;
  • Protect the environment.

Fume hoods may also offer explosion protection and protection against spill contaminates. Workers in laboratories, as well as the entire environment, have to be protected against the risk of experiment accidents. This is why all laboratories should be equipped with at least one fume hood.


Fume hoods can easily protect workers in buildings in which hazardous or noxious chemicals are released during various types of experiments, during testing or research. Actually, these great devices are found in all buildings in which noxious gases can be generated and released.

Fume hoods are designed to keep the environment safe, too, so they will not only offer protection to the user. As contaminated air is drawn into the device and filtered before being released back in the environment, no gases or chemicals will affect the environment.


Even though these devices are necessary in all laboratories, they have one major disadvantage. Fume hoods consume an impressive amount of energy. Actually, laboratory fume hoods can consume about 3 to 5 times more energy than a home. As they filter, control and move air, fume hoods require a high amount of energy to run.


Which type of laboratory fume hood is right for your lab?

When thinking about purchasing a fume hood system for your lab, you need to consider a series of factors. Below are listed some of the most important ones.

  • Type of work performed;
  • Air consumption;
  • Safety;
  • Convenience;
  • Energy consumption;
  • Work flow.

Laboratory fume hoods usually are qualitative products that can control the exposure to toxic or flammable vapors. A good fume hood will exhaust hazardous gases and vapors, protecting workers and the environment.

Things You Should Know About Fume Hoods Types

Fume hoods are devices which can be used with ventilation purposes. They have the ability to limit the exposure to noxious fumes, but also vapors and dust. Such devices, regardless of their types, usually have quite impressive dimensions and so they need a lot of space to be stored. Nowadays, there are two main type of the devices known to exist. They are the ducted and recirculating fume cupboards. No matter the type chosen, you should know that all are going to work while basing on the same principles. Air is drawn in from the front side, being then filtrated and fed back into the room, or eliminated outside the building. 

There are numerous types of ventilation devices that can be used today. Besides the fume cupboard, clean benches, bio-safety cabinets, glove boxes and snorkel exhausts, can also be used. They are going to have as major purposes protecting the user, but also the environment against harmful vapors. As there are different types of devices of this kind, they are all going to offer different levels of performance. The constant volume, variable volume, ductless and laminar flow, are the most popular fume cupboard types. The constant volume fume hood is going to run on constant speed all the time. This means that it can save a lot when it comes to energy consumption. However, it has the major disadvantage of being quite noisy, making this way the working environment really unfriendly. The variable volume fume hood is a device considered to be very safest, offering the possibility to adjust speed.

The ductless and the laminar flow fume hoods are very popular today. The ductless device will extract the air from the room and filter it, before returned back into the room. These devices are much appreciated for their high efficiency, but also for the fact that they are able to work while consuming less energy. The laminar flow works on a system based on the reverse process of the one supposed by the ductless fume hood. Regardless of their types, all fume hoods are going to have an audible and visual alarm to indicate to the user when something is wrong with the system. The device should be handled only by authorized personnel when it comes to all adjustable changes. Annual maintenance of the devices will be required in all cases, as well as periodic fume hood function inspection, to make sure that it has not been harmed or damaged.

Ductless Fume Hoods

Filed under: Fume Hoods - 28 Jun 2010  | Spread the word !

A fume hood is a device that resembles a cupboard and is designed to keep dangerous fumes and vapors out of the environment during laboratory experiments. There are two basic types of fume hoods, ducted and ductless (also called recirculating). Both types of hoods follow essentially the same principles. Contaminated air is sucked in from the open or front part of the cabinet. The air is then purified and released outside the building (ducted fume hoods) or released back into the room (recirculating fume hoods).

There is some debate in the scientific community as to which type of fume hood is better. Proponents of ductless fume hoods point out that ductless hoods are less expensive and require less maintenance that ducted hoods. Ductless hoods are also more portable. And a quality ductless fume hood will take constant readings of the airflow and alert the user if there is a problem or if the filter needs to be changed.

But not everybody is crazy about recirculating fume hoods. The Princeton University Laboratory Safety Manual specifically warns researchers against using ductless fume hoods. They argue that the filters do not always work properly and that the potential for toxic air being released back into the laboratory is high. They also argue ductless fume hoods are not equipped to handle emergency events, like a toxic spill.

Perhaps there is no one size fits all answer. Before selecting a fume hood, a laboratory should consider its budget, its needs for flexibility, and the toxicity of the materials being examined. A small laboratory with a tight budget that is working with minimally toxic materials might well benefit from a ductless fume hood, whereas a laboratory dealing with more dangerous materials might decide it worth the extra money to invest in a ducted fume hood.
