Description
What is Fume Hood Exhaust Fan
A reliable engineering piece often found in labs, fume hoods remove vapors, dusts, gases and fumes that are created. within the hood. As air flows into the hood, a fume hood exhaust fan system removes these toxic chemicals. There are two types of fume hoods commonly used today: Ducted and ductless.
Protection of Personnel
Principal purpose of a fume hood exhaust fan is to protect laboratory staff from harmful substances. When breathed or in contact with the skin or eyes, fumes and vapors produced by chemicals, volatile substances, or biological agents can be hazardous or toxic. Fume hood exhaust fan create a physical barrier between the worker and the hazardous materials, preventing direct exposure and minimizing the risk of inhalation or contact.
Containment of Hazardous Substances
Fume hood exhaust fan are used to keep hazardous pollutants contained in the workplace. They provide a safe environment in which to undertake chemical reactions, sample preparations, or other laboratory activities involving volatile, poisonous, or caustic compounds. The hood's construction, which includes a clear sash or sliding door, works as a physical barrier, preventing fumes, gases, or particle matter from escaping.
Ventilation and Exhaust
To ensure a controlled airflow within the workspace, fume hood exhaust fan use a ventilation system. The airflow from the laboratory is directed into the hood, catching and trapping the hazardous gases and chemicals. The trapped fumes are then securely expelled to the outside environment via a duct system by the ventilation system. This continuous airflow helps to minimize the accumulation of harmful substances in the workspace and maintain a safe working environment.
Environmental Protection
Fume hood exhaust fan have an important function in environmental protection in addition to protecting workers. The fume hood exhaust fan exhaust system guarantees that harmful vapors and substances are safely sent outside the building. This minimizes the influence on air quality and the risk of contamination or pollution by preventing the release of hazardous compounds into the laboratory or surrounding environment.
Compliance with Safety Regulations
Fume hood exhaust fan assist laboratories in meeting regulatory requirements and standards for occupational health and safety, environmental protection, and laboratory operations. Many regulatory authorities and organizations have specific criteria and rules for fume hood exhaust fan design, installation, operation, and maintenance. Compliance with these rules guarantees that laboratories keep a safe working environment and follow best practices when handling dangerous compounds.

How To Meet Lab's Fume Hood Exhaust Fan Requirements
Depending on your lab, you may need different specifications for your fume hood blower and exhaust fans. Let's take a look at how to meet the requirements of your lab.
What type of fume hood exhaust fan do you need?
Which type of fume hood exhaust fan you need depends on the intended use. If you are venting non-toxic materials, for example, you could use a fume hood exhaust fan coated with epoxy.
If the purpose is to mix acids, you will need an acid-resistant fume hood exhaust fan. Pvc is often the best material choice for perchloric acids and other corrosive operations.
Where the chemicals in your lab are moderately or highly corrosive, fiberglass is also a good option. If your work is volatile, there are even fume hood exhaust fan with explosion-proofing and those that are resistant to sparks.
These fume hood exhaust fan will often come with an enclosed motor that ensures fumes in the air stream won't encounter a spark or touch the motor.
If there's any chance of fumes in your lab catching on fire, spark resistance should prioritize.
Tip: Unsure what type of fume hood exhaust fan you need? Match the fume hood exhaust fan to the material of the fume hood liner for a good estimation.
How to choose the right size for your fume hood exhaust fan
Next, you'll need to decide what size you'll need for your operations. This refers to the power of the fume hood exhaust fan 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 fume hood exhaust fan is not immediately the best option. If a fume hood exhaust fan 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.
How many operating speeds does your fume hood exhaust fan need?
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 fume hood exhaust fan with multiple speed settings that will allow you to alleviate the burden of these costs.
Intelli-sense multi-speed fume hood exhaust fan can operate at up to three speeds which are programmed through a control box. This is located on top of the hood.
A fume hood exhaust fan 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 fume hood exhaust fan.
The right material for your exhaust system
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:
Pvc: This is intended for use with corrosives.
316 stainless steel: Suitable for use with solvents.
If you handle both corrosives and solvents, always ensure your duct system can handle the more aggressive chemical.

Before we wrap up, here are some tips to keep in mind to ensure a fume hood operates efficiently.
Keep chemicals or lab equipment away from the fume hood. It should not be used for storage, but if you have to place something inside, put it on top of blocks to allow airflow below.
Permanently remove obstructions from the hood slots and baffles. This ensures a good airflow stays in place.
Follow manufacturer's guidelines for replacing your fume hood exhaust fan and other equipment. This will also indicate how much distance to maintain between the hood and your work.
Design your laboratory in such a way that fume hoods are kept away from outside airflow influences. It shouldn't be placed near a door or open window.
If you follow these tips, you shouldn't go too far wrong!
