Portable fume hoods, also known as ductless fume hoods, are movable enclosures with a sash that filters hazardous vapors, particles, and fumes from the lab by use of carbon and/or HEPA filters which can be chemical specific. These fume hoods can be easily move from location to location and require no installation, unlike ducted fume hoods.
It is important to note that some chemicals are not able to be filtered effectively and the types of chemicals being used are to be taken into consideration. Other considerations are filter lifespans, applications, and overall costs.
Benefits of Portable Fume Hood
Hoods Are Movable
They can be shared among various projects at different times ofportable fume hood the day or on different days of the week.
Many ductless fume hoods are on wheels, making it easy to position them when and where needed, including when they are not in service. This level of mobility is impossible with ducted fume hoods, which are permanently connected to your HVAC system.
Are Less Expensive
The initial cost of a portable fume hood is almost always less than the cost of a ducted unit. That's because portable fume hoods don't require the extensive ductwork and structural modifications that ducted fume hoods need. Ducted fume hoods often need significant changes to the building's HVAC system to ensure proper ventilation as well. This can be costly. Because portable fume hoods are self contained, they don't require these modifications.
Portable Units Are Easier To Install
For many of the same reasons outlined above, portable units are easier to install. In fact, a ductless fume hood is often ready to go immediately after delivery. Workers simply insert the appropriate hepa filter or carbon filter, roll it to the workstation and plug it in.
Allow For Scalability
Portable fume hoods offer significant scalability advantages for lab operations, making it easier to adjust to varyingportable fume hood business demands and project scopes.
When expanding your lab, adding portable fume hoods can be done quickly and without the need for extensive renovations or infrastructure upgrades. This allows for rapid scaling to accommodate increased workloads or new types of research and development activities.
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.
Bench-top Fume Hood:
Bench-top fume hoods are hoods that are placed on the top of a work surface. They are, on average, about three feet from the floor. This type of hood requires ductwork, a base cabinet, a work surface, and an exhaust blower for it to function properly.
Walk-in Fume Hood:
Also known as a floor-mounted fume hood, a walk-in fume hood does not sit on another surface. This type of fume hood is similar in size to a small closet and comes in a wide variety of measurements to best fit your needs. Walk-in fume hoods are best for when working with oversized tools or equipment.
Double-faced Fume Hood:
Double-faced fume hoods are just that, double-faced. This means that there are workspace entrances on both sides creating a 360-degree viewing area. Like portable fume hoods, these can also be moved with ease to different areas. The most common use for double-faced hoods is in classrooms or other learning environments where demonstrations are given regularly.
Size of the Portable Fume Hood
The available space in the lab: If you have limited space, you will need to get a Portable Fume Hood that optimizes it. The area will determine the Portable Fume Hood's width, length, and height.
For example, a bench-top fume Portable Fume Hood would be ideal if the only available space is on a work surface. These Portable Fume Hoods do not have a mount or support system; thus, they sit on work surfaces.
Lab equipment: The type of equipment you will have inside the Portable Fume Hood and the dimensions play a significant role in determining the size of a fume Portable Fume Hood. The larger the equipment, the larger the Portable Fume Hood you will need and vice versa.
For example, floor-mounted or walk-in fume Portable Fume Hoods are installed from the floor up instead of sitting on another surface. They resemble a small room and allow you to work inside the space. Ideal if you need to use oversize tools and equipment or robots while working with toxic chemicals.
The number of users: If more than one person uses the Portable Fume Hood simultaneously, you may want to consider a fume Portable Fume Hood that allows access from either side. If you need to use it in different locations, consider getting a moveable option such as a ductless unit.
What to look for in a Portable Fume Hood
Size.
A basic starting point when shopping for and specifying a Portable Fume Hood is size. builds custom Portable Fume Hoods, so even if your size requirements are unusual, we can build a Portable Fume Hood to fit your space.
Materials.
Some chemistries require specialized materials for containment. Highly corrosive acids at high concentrations, for example, often require a Portable Fume Hood constructed from polypropylene rather than stainless steel for better corrosion resistance. For hydrofluoric acid, polycarbonate is the preferred material for the sash, to avoid etching of a glass window. Knowing the expected chemistry that will be put in the Portable Fume Hood is crucial to ensuring years of reliable functioning.
Standards.
Sometimes a "one-size-fits-all" Portable Fume Hood just won't work. In those cases, look to the applications engineers at Best Technology for a customized Portable Fume Hood.
Window orientation.
Some Portable Fume Hoods use a horizontal sliding window, which limits the access of the operator to the working area inside the Portable Fume Hood. Look for a vertically sliding window (sash), so that users have more available working area in the interior of the Portable Fume Hood. Best Technology offers Portable Fume Hoods with counterbalanced, vertically sliding windows.
What Are the Applications and Versatility of a Portable Fume Hood?
Chemical Handling and Analysis
In laboratories, Portable Fume Hoods are often used for chemical handling and analysis. They provide a safe atmosphere in which to work with volatile, poisonous, or caustic substances. Portable Fume Hoods ensure that reagents, solvents, acids, bases, and other chemical compounds are handled safely. They make it easier to weigh, mix, dilute, and transfer chemicals, as well as conduct experiments and reactions that produce potentially dangerous gases or vapors.
Biological Safety
In biosafety applications, a Portable Fume Hood with adequate filters or ventilation systems are used. Working with infectious materials, biological agents, or genetically modified organisms (GMOs) requires a controlled environment, which these hoods provide. They safeguard researchers from biological dangers and prevent diseases or pollutants from entering the laboratory environment.

How a Portable Fume Hood Works
A Portable Fume Hood is a ventilated enclosure in which gases, vapors and fumes are captured and removed from the work area. 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.
Depending on its design, the sash may move vertically, horizontally or a combination of the two and provides some protection to the hood user by acting as a barrier between the worker and the experiment.
The slots and baffles within the hood direct the air and, in many hoods, can be adjusted to allow the most even flow. It is important to prevent the baffles from becoming blocked, by excessive material storage or equipment, since this significantly affects the exhaust path within the hood and as a result, the efficiency of hood capture.
The beveled frame around the hood face, called the airfoil, allows for even air flow into the hood by eliminating sharp curves to reduce turbulence.
Provides a full personal protection solution in the lab in the form of high-quality high-efficiency durable Portable Fume Hoods. They come in various sizes like 1500 mm and 1200 mm width (5' and 4'), both 3' deep and about 7.4' tall. They are all floor-mounted Portable Fume Hoods.
The exterior of the chemical hood is made of 1.2 mm or 1.5 mm thick CRCA steel, which is electro-galvanized with epoxy powder coating and rigid structure, according to IS:513 standards. Labkafe Portable Fume Hoods are chemical and heat resistant and fire retardant as well. It has a drip plug and catcher system in place to collect anything that may spill out.
The insides of the Portable Fume Hoods are built with 6 mm thick panels with a smooth finish for easy cleaning. The sass or shutter is mounted on a hinged panel for easy access; and the airflow is auto-bypass type. The working surface table top is of jet black granite (20 mm thick) with a chem-resistant coating; it also resists regular scratches and corrosive spillage.
The sass in these Portable Fume Hoods is made of toughened float glass that is at least 5 mm thick. It has about two and a half feet of operating height. The sass is counterbalanced and smooth, so it's very easy to operate and doesn't jam. There's also a 20-watt lamp inside for clear viewing. Don't worry, the light is covered in fume-proof housing.
How often to clean a Portable Fume Hood
Type of Portable Fume Hood: Ductless Portable Fume Hoods need filters to remove toxins to recirculate air into the lab. Make sure you're using the right filter for the chemicals you intend to use in the hood. Ducted hoods will exhaust fumes out of the laboratory.
Previous uses: What sort of chemicals were last used in the Portable Fume Hood? Make sure to use cleaning solutions that won't react to lingering chemicals. Mild soap and water is the safest option. Test your cleaning products on a small area first to make sure there aren't any damaging reactions.
Variety of use: If you use the hood for the same process on a regular basis, you may be able to go a long time between cleaning. But, if you're using the hood for a variety of processes, you need to clean it before you change processes.
Frequency of use: If you use a Portable Fume Hood on a regular basis, develop a cleaning schedule. If your hood isn't used often, clean it immediately afterward. Ducted Portable Fume Hoods used with low-risk chemicals can go months without a clean. Portable Fume Hoods used for dangerous or varied processes need cleaning after every use.
Type of chemicals: Certain chemical residues may be dangerous if left inside. Perchloric acid hoods come with a washdown system to prevent residue from exploding.
Stain capability: Although stains won't hurt, it's nice to have your equipment look good. Certain processes can leave residue that stains, such as soot. Clean up after messy experiments to keep your Portable Fume Hood in good condition.
