The thing to know about Portable Ductless Fume Hood

Downflow Workstation

A portable ductless fume hood is a device used to control volatile organic compounds (VOCs) in an enclosed space to ensure the safety of workers by preventing exposure to toxic gases. There are many different types of regulations and guidelines for handling hazardous materials. It is important to understand them because regulations sometimes vary across states, countries, or even localities. The OSHA regulations for handling VOCs are a good example of this. All employers must follow the standards outlined by OSHA if they handle chemicals that involve health hazards, whether in VOCs or other chemical substances such as asbestos or hydrogen sulfide.

What is Portable Ductless Fume Hood?

A portable ductless fume hood is a polyethylene enclosure that is portable and can be used to provide a safe working environment in an area that potentially generates hazardous fume, smoke, or vapor. It allows the safe handling of toxic and flammable chemicals without adversely affecting indoor air quality.

Since the 1950s, portable ductless fume hoods have been designed by various researchers in different jurisdictions. They were designed to be used in standard equipment like laboratory hoods to reduce unnecessary waste of laboratory chemicals and aid in the safety of workers. Some were designed to work as fume cupboards, while others were designed to work as a Class I biological safety cabinet (BSC).

How does it work?

The hood has an internal blower system, which moves the air through the filtering device and removes 99.97 percent of airborne particulate. The blower can also cool flammable or toxic materials with a temperature of up to 110 degrees Fahrenheit. The fume hood has a five-foot height, four-foot width, and five-foot depth. They are designed to fit in a standard laboratory benchtop so that users would not need to move it from where they are working.

The cabinet is equipped with a mounting hook for hanging additional tools and equipment such as an electric hot plate, combustion engines, and other laboratory equipment like scales or balances (depending on the type of operation).

Benefits of Portable Ductless Fume Hood:

The portable ductless fume hood allows a user to work safely and efficiently. It is easy to transport, lightweight and even can be used as a chemical shield cabinet. Users have reported many positive benefits after using them.

  • Protection from toxic chemicals that could cause serious harm
  • Meeting OSHA guidelines for handling hazardous VOCs
  • Fume hood often increases efficiency by containing fumes that make it difficult to see or smell vapors or harmful ones.
  • The fume hood combines flexibility with safety. It can be used by people in various locations in the lab, including the fume hood, and it can be moved to different locations as needed.
  • It improves workplace efficiency by reducing workplace waste and increasing workplace safety.
  • The fume hood helps workers stay productive because they are working in a safe and free of distractions caused by fumes and vapors that go unnoticed.
  • Allows for more efficient use of chemicals because chemicals are not wasted due to fumes escaping from poorly fitted lids or improper ventilation.

What are Benchtop Ductless Fume Hoods?

Benchtop ductless fume hoods are designed especially for conducting experiments on hazardous VOCs. They are built with high-efficiency filters to capture small particles, such as dust and dirt, that escape from the hood at sealed orifices and are not captured by the exhaust fan. In addition, the fan is large enough to remove any small particles without removing important chemicals in the work area.

The filter can be placed directly on the benchtop to decrease the work time required to dispose of hazardous VOCs. In addition, to reduce the risk of contaminants to the work area, the benchtop fume hoods can be used in conjunction with a porous absorbent mat strategically placed on the benchtop beneath the filter.

Different forms of fume hoods?

Fume hoods are designed to make workplaces safer for workers, but they have several functional differences that make them better suited for handling particular operations. For example, depending on the situation, you may want to use a laboratory hood designed to contain vapors and fumes. Laboratory fume hoods are also called mini fume cabinets or laboratory fume cupboards. Other types of fume hoods include:

  1. Prep-station hoods: Prep-station fume hoods prevent exposure to airborne contaminants during meal preparation in hospital settings. These hoods are properly equipped with a full-face shield since the risk of infection is higher than in other types.
  2. Animal care hoods: Animal care fume hoods are designed to keep animals in a safe environment. If an animal enters a laboratory fume hood by accident, it may be killed or injured by its equipment. Laboratory animal care fumes hoods give animals a safe environment to live in and contain noxious fumes to protect workers from injuries and infections that can occur from exposure to pathogens.
  3. Cabinet for infectious waste: Cabinet for infectious waste is used to dispose of bio-hazardous medical materials from hospitals and research facilities.


Portable Fume Hoods by Global Lab Supply are a common piece of laboratory equipment used in scientific labs and other industries such as hospitals and research facilities. They are designed to protect workers in contaminated areas and make work more efficient by reducing the time needed to clean up after experiments with toxic chemicals. The main advantage of these fume hoods is that users can easily move them from one place to another.
