                     Portable Fume Hood and its benefit 
Lab equipment comes in many different configurations to meet the variety of substances and 
methods that various labs use in. Generally, lab equipment supplier provide many type of lab 
equipments for different R&D applications such as Fume Hood, Laminar Air Flow, Pass Box and 
many more. It can be challenging to select the best equipment for your application due to its 
complexity. You can use this study to decide if a portable fume hood is the best option for your lab 
What is a Portable Fume Hood? 
Portable fume hood is also known as a re-circulating fume hood, because it filters the air in your lab 
and then circulates it. They are separate lab enclosures that work by continuously blowing air across 
the workspace and pulling it through a filter to remove pollutants, particles, and chemical odours. 
Portable fume hoods do not have connections to the building's HVAC system, in contrast to ducted 
fume hoods. They reuse the clean air inside your laboratory as opposed to venting it outdoors like 
ducted hoods do. 
Uses for portable fume hoods 
 Light to medium workload labs that frequently use ten or less compounds, as well as chemicals in 
small amounts of 500 ml or less, benefit from the usage of portable fume hoods. They perform best 
in laboratories with knowledgeable and skilled lab staff as well as in those without access to outdoor 
venting. Employees shouldn't be exposed to contaminants for longer than two to three hours each 
day. 
Advantages of portable fume hood 
In contrast to ducted fume hoods, portable fume hoods can offer a variety of advantages. 
Movable- The majority of ductless fume hoods are moveable, allowing for sharing between several 
projects at various times of the day or on various days of the week. Several portable fume hoods 
have wheels, making it simple to move them to the appropriate location and position when needed. 
When not in use, they may also be easily rolled away. Ducted fume hoods that are always attached 
to the building's HVAC system, are unable to be moved about. 
Saving energy- Portable fume hood may use less energy than a ducted fume hood, which frequently 
operates continuously because it only consumes electricity while it is in use. Additionally, ducted 
fume hoods must move air farther, which uses energy. 
Less costly- A portable fume hood's initial cost is generally less than that of a ducted device. Ducted 
units incur additional expenditures for connecting to the building's HVAC system on top of the 
purchasing price. Since they feature fewer motors and fan that normally only run when the machine 
is in use, portable/ductless fume hoods offer lower daily operating costs than ducted hoods. 
Simple to install- Frequently, a portable fume hood can be used right away after delivery. Simply 
wheel it to the workstation, plug it in, and insert the proper filter. In contrast, ducted fume hoods 
need more intricate connections and could need for licences, permits, and approvals before they can 
be used for the first time. Portable fume hoods can be easily maintained by lab staff, however 
ducted fume hoods may require training for building engineers to ensure correct maintenance and 
operation. 
The limitations of portable fume hoods 
 Under certain circumstances, a portable fume hood might not be the ideal option. The hood will be 
ineffective if the substances in the lab can't be successfully eliminated by charcoal or other easily 
accessible filters. 
They might not function properly in extremely hot environments or when exposed to a lot of 
chemicals. They are not a wise choice for labs staffed by inexperienced or student workers. 
Additionally, a portable fume hood's filter needs to be replaced on a regular basis. It is necessary to 
rely on lab staff to complete this activity as needed, and the expense of repeated filter replacements 
may eventually outweigh the initially modest acquisition costs. With current filters, some substances 
cannot be efficiently regulated. 
Should Your Lab Consider a Portable Fume Hood? 
 For your lab, a portable fume hood can be the best option. You should discuss your application with 
a professional fume hood manufacturer before continuing. An expert in fume hoods can evaluate 
your laboratory's needs and work with your budget to assist you chooses the best choice to protect 
the environment and your lab staff's safety.
