Laboratory fume hoods can be fabricated from different materials and include specific surface types, such as stainless steel, fiberglass, PVC or even polypropylene.
Chemical fume hoods are a mainstay for most research and educational labs. They protect users from chemical and radiological exposure. Ideal if you plan on conducting experiments that use toxic or volatile chemicals to lower the chances of inhalation.
Laminar flow hoods protect the samples from contamination. They do not offer lab personnel any protection; thus, you must not use them when working with toxic or infectious chemicals.
Demonstration or educational hoods: These are optimized for teaching. An example is the double-faced fume hoods, which have entrances on both sides, allowing for 360-degree viewing.
Biological Safety Cabinets (BSCs) have a different application and do not fall within the fume
hood category. They are, however, a must-have for labs that handle
viral microbes and infectious diseases.

How to Choose the Right Size for Your Fume Hood Blower
Next, you'll need to decide what size you'll need for your operations. This refers to the power of the fume hood blower and is essential to ensuring your equipment transfers enough air to keep your lab free of contamination.
It's worth noting that choosing the most robust blower is not immediately the best option. If a blower is too powerful, it could strain the ductwork and create turbulence.
Calculating the required power isn't easy. You'll need to consider the static pressure present in your duct system. This is calculated based on the diameter, duct length, number of bends, and velocity at which the fume will operate.
Talk to your manufacturer or reach out to CFI and consult a fume hood expert for the right choice.
Exhausting tempered air from your fume hood is often one of the most costly energy uses for laboratories.
That's why depending on your operations, you might benefit from a blower with multiple speed settings that will allow you to alleviate the burden of these costs.
Intelli-sense multi-speed blowers can operate at up to three speeds which are programmed through a control box. This is located on top of the hood.
A blower with this function is very versatile. It could operate at lower speeds during the night, using the least amount of air. More extensive labs that operate on a constant volume can instead use belt-driven single-speed blowers.
To ensure a safe exhaust system, you need to consider the correct material for your ductwork.
Your ducting should be compatible with local fire codes. Most importantly, make sure it's compatible with the chemicals it will be exposed to in your lab. Most commonly, duct systems will be fashioned from:
