What are the different types of fume hood design?
Sep 30, 2025
Hey there! I'm a supplier in the fume hood design business, and today I wanna chat about the different types of fume hood design. Fume hoods are super important in labs, industrial settings, and other places where you need to handle hazardous chemicals or materials. They help keep the air clean and protect people from harmful fumes. So, let's dive in and take a look at the various types out there.
1. Ducted Fume Hoods
Ducted fume hoods are one of the most common types. These bad boys are connected to an exhaust system that vents the fumes outside the building. They're great for dealing with high - volume and highly toxic chemicals.
The way they work is pretty straightforward. When you turn on the fume hood, air is drawn into the hood through the front opening, which is called the face. The contaminated air then travels through a duct and gets expelled outside. This ensures that the indoor air quality remains safe.


One of the key features of ducted fume hoods is their high efficiency. They can handle a wide range of chemicals, from acids to solvents. However, they do require a proper exhaust system, which can be expensive to install and maintain. If you're interested in ducted fume hoods, you can check out our Duct Fume Hood page for more details.
2. Ductless Fume Hoods
Ductless fume hoods, on the other hand, are a more flexible option. They don't need a duct system to vent the fumes outside. Instead, they use filters to clean the air before recirculating it back into the room.
These fume hoods are great for small labs or areas where installing a duct system is difficult or expensive. They're also easier to install and move around. But they do have some limitations. The filters need to be replaced regularly, and they may not be suitable for all types of chemicals. For example, they may not work well with high - boiling - point solvents or large amounts of particulate matter.
If you're considering a ductless fume hood, make sure to understand the specific chemicals you'll be working with and choose the right filter. This will ensure that the fume hood can effectively remove the contaminants from the air.
3. Exhaust Fume Hoods
Exhaust fume hoods are designed specifically for exhausting fumes. They come in different shapes and sizes, depending on the application. Some are designed for general laboratory use, while others are more specialized for specific industries.
These fume hoods typically have a high - velocity exhaust system that can quickly remove fumes from the work area. They often have adjustable baffles inside the hood to control the airflow and ensure that the fumes are properly captured.
Exhaust fume hoods are essential in environments where there's a high risk of exposure to toxic fumes. If you're in the market for an exhaust fume hood, you can visit our Exhaust Fume Hood page to learn more.
4. Walk - In Fume Hoods
Walk - in fume hoods are large enough for a person to walk into. They're used in situations where you need to work with large equipment or perform operations that require a lot of space.
These fume hoods are often used in industrial settings, such as chemical manufacturing plants or large research labs. They have a high - capacity exhaust system to handle the large volume of air and fumes. The design of walk - in fume hoods also takes into account the safety of the workers inside, with features like emergency shut - off switches and proper lighting.
However, walk - in fume hoods are expensive to install and operate. They require a significant amount of space and a powerful exhaust system. But if you have the need for a large - scale fume - handling solution, they can be a great option.
5. Benchtop Fume Hoods
Benchtop fume hoods are smaller and more compact. They're designed to sit on a laboratory bench or table. These fume hoods are perfect for small - scale experiments or for working with low - volume chemicals.
They're easy to install and don't require a lot of space. They can be a cost - effective solution for small labs or educational institutions. Benchtop fume hoods often come with adjustable sashes, which allow you to control the amount of airflow and access to the work area. You can find more information about Fume Hood Sashes on our website.
6. Canopy Fume Hoods
Canopy fume hoods are typically used in industrial kitchens or areas where there's a lot of heat and steam. They're designed to capture and exhaust the fumes and odors generated by cooking or other heat - producing processes.
These fume hoods are usually installed above the cooking equipment or other heat sources. They have a large surface area to capture the rising fumes. Canopy fume hoods often come with grease filters to remove the grease particles from the air before it's exhausted.
While they're mainly used in the food industry, they can also be adapted for other applications where there's a need to capture and exhaust fumes from a large, open area.
7. Custom - Designed Fume Hoods
Sometimes, off - the - shelf fume hoods just won't cut it. That's where custom - designed fume hoods come in. We can design and build fume hoods to meet your specific requirements. Whether you need a unique shape, size, or function, we can create a fume hood that's tailored to your needs.
Custom - designed fume hoods are great for specialized applications, such as working with radioactive materials or in cleanroom environments. We'll work closely with you to understand your needs and ensure that the fume hood meets all the necessary safety and performance standards.
Choosing the Right Fume Hood
When it comes to choosing the right fume hood, there are several factors to consider. First, think about the type of chemicals you'll be working with. Different fume hoods are better suited for different chemicals. For example, if you're working with highly toxic chemicals, a ducted fume hood may be the best option.
Next, consider the volume of fumes you'll be generating. If you're doing large - scale experiments or industrial processes, you'll need a fume hood with a high - capacity exhaust system.
Also, think about the space you have available. Benchtop fume hoods are great for small spaces, while walk - in fume hoods require a lot of room.
Finally, consider your budget. Ducted fume hoods can be more expensive to install and maintain, while ductless fume hoods may be a more cost - effective option in the short term.
