What is a Horizontal Flow Hood?
Figure 1 A Horizontal Flow Hood
A horizontal flow hood is a type of clean bench or laminar floor hood aimed at providing the user with a clean work area free from particulates and other possible contaminants. This is done by blowing laminar airflow over the working area.
This laminar flow hood gets its name from the way it operates. This guide has more information about its operating principle, so keep reading.
Due to its operation, a horizontal flow hood is one of the most sought-after laminar flow hoods. As such, it is used in various industries, mostly involving research and experimentations. It is also a nice choice for companies working on sensitive technology that does not need to expose the sample to the elements or other types of contaminants.
What is the Operating Principle of a Horizontal Flow Hood?
Figure 2 How a Horizontal Flow Hood Works
Unlike the vertical flow hood, where the air travels downwards, the air in the horizontal flow hood travels from back to front. This air is passed through the HEPA filter, which filters 99.99% of the particles.
Because of the design, the horizontal flow hood will require more space to set it up. Also, it needs more clearance at the rear to allow for air to get into the flow hood. Such means that the horizontal flow hood takes up more space than the vertical flow hood.
The horizontal flow hood might have some limitations depending on what you are working on. Let us say you are handling a project with soldering fumes or maybe fine powder. It will be harder to work better in such a case. This is because the fumes and powder might get blown into the operator’s face.
Consider looking at the product manual in detail to understand where best you can use the horizontal flow hood without risking the life of the operator.
What are the Common Applications of Horizontal Flow Hoods?
The horizontal flow hood will mostly be an ideal choice for those working in the research sector. The same works great for other industries such as manufacturing, aerospace, bioscience, food processing, and pharmaceutical production.
It is easy to see how its sterile environment will be a top choice for those working in the drug industry. The last thing you need is for the medication to be compromised.
Can Horizontal Flow Hoods Protect the User?
No. The horizontal flow hood is meant for protecting the sample in the work area from airborne particle contamination. It does not protect the user or the surroundings. So, before you can start handling may be toxic substances, you need proper protection. Always take extra caution when handling toxins, radionuclides, and other biohazardous materials in the horizontal flow hood.
What are the Benefits of a Horizontal Flow Hood?
Here are some of the pros that make more people consider getting themselves the horizontal flow hood.
– This type of hood is good for eliminating the turbulent effects seen in the vertical flow hoods. It is more convenient to operate and take items, which can effectively improvework efficiency. The horizontal flow hood is easy to operate because there is no glass in front of it.

You will tend to discover more benefits as you keep using the horizontal flow hood.
Why is a HEPA Filter Important for a Horizontal Flow Hood?
Figure 3 How a HEPA Filter Works
Zonsteel makes class 100 or ISO 5 horizontal flow hoods. To ensure such hoods meet the stringent standards, there is a need for using a HEPA filter.
A HEPA filter is important for filtering up to 99.99% of the particles in the air. The result is that the work area becomes sterile, thus suitable for the different applications you might have in mind.
The HEPA filter is further sealed with gel ensuring there are no leaks. You can now depend on Zonsteel horizontal flow hoods to provide you with the best work environment.
As much as the HEPA filter is good at its job, there is the need to ensure you always take good care of it. There is a need for proper maintenance of the filter to keep it in good condition. Inspect it every six months and replace it when it no longer works as expected.
Is the Air Blower in the Horizontal Flow Hood Noisy? What is the Airspeed it Generates?
The horizontal flow hood needs a constant flow of air over the work area. That is made possible with the use of an air blower mounted in the hood.
The best thing about this air blower should be its silent operating mode. You will always find it is a comfortable work environment when the blower can maintain a silent operation.
Also, the air blower is designed to be energy saving. Even if you have to run the horizontal flow hood for hours, it will not use a lot of energy.
It is energy-saving while at the same time able to generate big pressure. This is more reason to consider getting it.
In addition to being quiet, the air blower generates an airflow of 0.45m/s. This is the recommended airspeed for a Class 100 or ISO 5 laminar flow hood.
This kind of speed is good enough to prevent the contamination of the sample in the hood.

The horizontal flow hood, like any other machine, needs maintenance too. This time we are talking about its filter. If the filter is not working correctly, then it can lead to contamination.
It is best to start by inspecting the filter to ensure it is in the right working condition.
Remember, there are two types of filters in a horizontal flow hood. These filters include the primary filter and the HEPA filter.
The primary filter is expected to be dirtier as it traps the large dust particles. If it is too dirty, then proceed to replace it with a new pre-filter.
You still have to inspect the condition of the HEPA filter. In most cases, you will have to replace it after a couple of years of using it. Some people might try to wash the filter. However, it is not recommended unless it is a washable filter.
Zonsteel will have a detailed guide for the maintenance of the other parts of the horizontal flow hood. Make sure to follow the guide to keep the flow hood in great working condition.
