Laboratory Fume Hoods and Uses
Fume hoods are pivotal for keeping people safe around dangerous chemicals. Laboratory Fume hoods are used to limit the exposure of toxic fumes and vapours in the surrounding environment
In order to protect people from the harmful effects of these fumes, fume hoods are used to get rid of the harmful aspects and allow the individuals to work safely. Labs use fume hoods when working with substances that let off a harmful fume or odour. Scientists can work with substances directly under the fume hood, or simply place the substance in the fume hood after the work is done
The Different Types of Fume Hoods available with us
Each lab’s requirements are unique and customised provisions required. Metrolabs provides a variety of fume hood sizing options to suit every laboratory need.
DUCTLESS FUME HOODS
A Ductless fume hood uses carbon filters to remove fumes and vapours from a laboratory. Carbon filtration, an advanced technology used within a ductless fume hood, is an eco-friendly choice for both the user and the environment. Instead of funnelling the fumes outside, the fume hood filters out the harmful fumes and then returns the clean air back into the laboratory. Ductless fume hoods are also energy and cost efficient and even offer electronic monitoring in order to routinely test the performance of the filtration system.
CHEMICAL FUME HOODS
A Chemical fume hood is used in laboratories where dangerous chemicals are handled in the workplace. This type of hood is specifically designed to allow laboratory workers to work with these chemicals without exposing themselves to the harmful drawbacks associated with them. Featuring quality steel and a design that exceeds SEFA standards, this unit will ensure workers can work with chemicals safely. The innovative design of the fume hood allows users to have a full view of their work and laboratory through a sash.
>CANOPY FUME HOODS
The canopy fume hood is a ventilation system for non-toxic materials that removes heat steam and odors. These units are often used over ovens or steam baths and are mounted to a wall or the ceiling for easy removal and accessibility. These types of fume hoods can also be customized to fit the exact space in a laboratory in order to effectively ventilate the area.
EXTRACTOR ARM FUME HOODS
An Extractor Arm fume hood is a local exhaust ventilation device that ventilate local fumes, odors and air streams in a lab. The typical size of an extractor arm fume hood is 2”, 3” or 4”. Each of these sizes can be mounted on a bench, wall or ceiling. The variety of designs are to ensure the perfect fit for any laboratory or workplace.
LOW FLOW FUME HOODS
A Low Air Flow fume hood operates at a lower rate than a standard unit meaning they take up less space in a lab and can save up to 40% on an energy bill. They reduce energy intake by reducing the amount of conditioned air required to fill a room. You can check with an expert to determine if a low air flow fume hood is the right option for your lab.
ACID RESISTANT FUME HOODS
Acid Resistant Fume Hoods (Perclhoric/ Nitric/ Sulphuric/ Hyderochloric) Fume Hood is designed specifically to be used with perchloric acid in order to prevent perchlorate salt formations. These steel devices feature a bench top and are available in a variety of widths in order to fit any lab environment. The grade of steel used in the design of Perchloric Acid Fume Hoods provides the ultimate protection from the perchloric acid.
VARIABLE AIR FUME HOODS
A Variable Air Volume Fume Hood has control over the air that is exhausted from the unit and reduces the costs of the device by maintaining a constant velocity. These items are sold to be used with exhaust control systems that other manufacturers provide. They come with a sash in a full view version that allows for the user to have a clear line-of-sight while still protected as they work. It also provides a great deal of interior lighting to assist with visual clarity.
FUME HOOD ACCESSORIES
Common accessories include lab blowers, ventilation ducting in PVC, aluminum, stainless steel, sheet metal and lattice rod assemblies for distillation rack applications. Each accessory is specifically designed so the fume hood is easier to use for the lab worker and safer for the materials in the lab environment.
Ventilation Systems Remove Harmful Materials from Labs
Chemical fume hoods play a vital role in containing or removing hazardous fumes, vapors, or radioactive materials from a lab setting. Fume hood technology has continuously improved for more than 50 years to enhance safety, efficiency and ease of use. Properly certified hoods from Metrolabs Laboratory Furniture allow lab personnel to work with harmful materials at close range, safely and conveniently.
Metrolabs designs and outfits laboratories as a complete system and will help you choose the right model, design and positioning for operational safety and efficiency in the laboratory. Your choice of hood design and model depends heavily on your application. Metrolabs Laboratory Furniture has extensive experience outfitting labs with safety equipment across all industry types.

Biological Safety Cabinets
Biological safety cabinets (BSC) are similar to chemical fume hoods as they ventilate laboratory workspaces. However, BSC are specially designed for the removal of biological pathogens. Three different classes (Class I, Class II, and Class III) offer various levels of protection. The type your lab needs will depend on the pathogens used in your applications.
BSC are recommended for medical laboratories, food processing plants, and water and wastewater management facilities. Learn which class of cabinet is right for your work.
Green chemical fume hood options include:
- Bench or floor-mounted (walk-in) models
- Customized hoods for specific applications
Custom hood sizes and materials are available. Talk to our chemical fume hood sales team for detailed options or visit Laboratory Fume Hood Energy Model to calculate your fume hood energy Indiage.
Designing Lab Ventilation Systems: Professional Experience Matters
A properly functioning fume hood can be the difference between a safe lab and a dangerous work environment. Fume hood placement is just as important as the type. The right location will ensure you have optimal ventilation for your work. Using CAD renderings, our award-winning lab designers will find the right placement for all your casework furniture, ventilation systems, and safety equipment.
