Product Description
Product Description
A ductless fume hood is a stand alone, compact workstation that provides a continuous flow of air that filters hazardous fume vapors out, recirculating clean air back into your working environment. Because the air is recirculated, no exterior ducting or makeup air is necessary. These air filtration systems are designed to keep harmful airborne contaminants away from the operator's respiratory zone while they work within the hood.
Also referred to as exhaust hoods, these containment systems are used for a variety of applications including chemical fume control, powder and dust removal, solvent vapor control, pharmaceutical powder filling, light grinding, acid gas fumes, anesthesia gas containment, epoxy fume control and other applications that produce hazardous particulates and fumes.
Ductless fume hoods offer several key advantages when weighing your options versus a ducted fume hood:
-No costly ducting or venting
-No permitting issues for venting outside of the building
-Adaptable (mobility and ease in change of layout)
-Environmentally friendly
-Significant energy cost saving

More About the Fume Hood
A ductless fume hood may not be suitable for the application being practiced as there are certain features of a ducted hood that may suit your needs more:
Certain chemicals/gases carry a low molecular weight and are not efficiently captured through a carbon filter (ie. methane, butane, propane gas)
Loading: the amount of uses per time frame may require us to directly vent outside versus running through a particular filter "too much"
For example: If your application is using acetone gas and evaporating gallons per day, running it through a carbon filter in excess may saturate it past an effective point, rendering it to be useless or replaced at a significant rate.
Benefits of a Ductless Fume Hood
-Minimal installation costs-no external ducting or venting
-Portable
-Minimal maintenance
-Environmentally friendly
-Significant energy cost savings
-No permitting issues for venting outside (ie. EPA air sampling

FAQ
What Is a Fume Hood?
A fume hood is a piece of laboratory equipment designed to minimize a person's exposure to hazardous chemicals. The fume hood draws away harmful vapors so lab employees can work with chemicals without the risk of accidental exposure. The air is extracted from the fume hood and filtered to remove dangerous vapors, and then either exhausted outside of the building or recirculated back into the lab.
How Does a Fume Hood Work?
The fume hood works by using a sash (a window that opens or closes to protect the user) to contain the vapor and keep it away from the user's face or to prevent it from drifting out into the rest of the laboratory. Blowers draw in air from the room, through a filter or number of filters within the fume hood and towards an exhaust area.
To safely work in a fume hood, keep all work at least six inches away from the plane of the sash. This will ensure fumes are pulled away from the user. Also, make sure the hood sash remains closed as much as possible and keep the hood slots and baffles free of any obstructions by containers or equipment. Never place your head inside the fume hood when working with chemicals.
The airflow will differ depending on the type of hood you use. For a constant air volume (CAV) hood, the fan has only one speed, providing a stable and continuous airflow. A variable air volume (VAV) hood allows users to adjust the velocity of the exhaust for added versatility, while reduced air volume (RAV) hoods offer lower airflow performance, making them ideal for working with less harmful compounds.
Why do fume hoods use so much energy?It's the air being sucked through the fume hood, not the fume hood itself that consumes so much energy. For health and safety reasons, labs use 100% outside air which must be heated or cooled for comfort before it is brought into the lab. In addition to the energy required to condition the air, a significant amount of additional electricity is required to run large fans to move the air through the building and through the fume hoods.How does shutting the sash save energy?Most fume hoods at Stanford are variable air volume (VAV), meaning that the fume hoods are designed to vary the air flow based on how wide open the sash height is. Sash position is connected to the building's ventilation system so that a building's fan speed and the volume of air moved is reduced when the sash is lowered.Is it safe to shut the sash?The sash is an important safety barrier between the fume hood interior and the laboratory, protecting the lab user. Sashes should be opened only to set up or modify an experiment. At all other times, shutting the sash is safest. When the sash is shut there is still some air flow through the hood to remove any fumes.How do I remind myself and my roommates to close the sash?You can post a sticker, like the one shown in the picture below, to remind yourself and your lab mates to close the sash when not in use. The sticker also educates new fume hood users tha a lower sash is safer, and that the sash should only be open when setting up and modifying experiments. Project Cases
