How does a fume hood work?

A fume hood is a ventilated enclosure in which gases, vapors and fumes are contained. An exhaust fan situated on the top of the laboratory building pulls air and airborne contaminants through connected ductwork and exhausts them to the atmosphere.

Different types of Fume Hood

Fume hoods(Polypropylene fume hoods) also work to protect you from explosions and chemical spills. The safety glass is designed to “spider” instead of shattering in the event of an explosion, keeping those in the area safe from glass and chemicals when explosions occur. Most hoods also include spill-containment features, which can be especially important when working with exceptionally hazardous materials.

Whether you work on personal projects,it’s important to determine what type of fume hood you should invest in.

Benchtop Fume Hood

A bench-top fume hood is a hood that sits on a work surface approximately 36” above the floor. Along with the hood, you will need a supporting base cabinet, a work surface, and an exhaust blower. This type of fume hood will need ductwork, which should be factored into your installation costs.

Floor Mounted Fume Hood

A floor mounted Fume Hood, or a walk-in fume hood, is installed from the floor up instead of sitting on another surface. It resembles a small room, allowing you to work inside the space. This is ideal when you may need to use oversized tools or equipment, such as drums, processing units or robots while working with toxic chemicals. The large doors allow you to roll large apparatus or tables into the area as needed. These fume hoods can range in size depending on your needs but are generally the size of a small closet. Standard models range from 6 to 24 feet wide, 7 to 16 feet high, and 4 to 8 feet deep.

Double Faced Fume Hood

A double-faced fume hood is most ideal for demonstrations. It has entrances on both sides and allows for 360-degree viewing. This type of fume-hood can come as a typical bench-top or wall installation or as a portable unit. These are usually in classrooms where teaching demonstrations are frequent.

Portable double-faced fume hoods are especially useful in shared learning environments, where the hood may need to be moved from one classroom to the next.

Portable Fume Hood

Portable fume hoods are also known as recirculating range hoods. They are ductless, which means that they operate off of a carbon filter system.

These Fume hoods Cabinet are easier to install, mobile, and use less energy. The installation process requires no ductwork or wall penetration. They’re usually smaller or on wheels, so you’re able to move them to different areas of your lab. If energy-usage is important, these are eco-friendly when compared to the energy usage of full sized Fume Hoods

While portable fume hoods may seem like an easier option, there are a few disadvantages to this model. The method in which toxins filter out can put workers at a higher risk of exposure. Filters also need regular maintenance.

Portable fume hoods are ideal if you work with less than 10 chemicals or small amounts of chemicals. The chemicals also need to be able to filter through the carbon.
