What is a Vertical Laminar Flow Hood?
Figure 1 A Vertical Laminar Flow Hood
A vertical laminar flow hood is essential for maintaining a clean work area with the absence of particulate contamination. This is done by providing a constant airflow over the surface to maintain a contaminant-free.
It is called a vertical laminar flow hood because of the design and the direction of the air over the surface. In this case, the air flows downwards as it is pumped from the top of the hood.
What is Laminar Flow?
Laminar flow means that the airflow within the entire body of the designated space remains at a uniform velocity and direction. So, if it is a vertical laminar flow hood, the direction and speed are maintained throughout. The same applies to the horizontal laminar flow hoods.
Laminar flow is incorporated in laminar flow hoods to help in creating clean enclosures important for multiple applications. Due to their operation principle, the laminar flow hoods are commonly used when working with semiconductors, biological samples, and many other sensitive materials.

Figure 2 Illustration of an ISO 5 Cleanroom
This means that the air cleanliness of the vertical laminar flow hood is of the highest quality. It is one of the top-rated clean areas compared to the other classifications. It is mostly achieved by using the HEPA or the ULPA filers, ensuring that the work area maintains a high level of cleanliness.
The ISO 5 clean area also needs a unidirectional airflow. That is something you will get with the vertical laminar flow hood. The air will sweep across the filters and down the hood at a velocity of 0.45m/s Upon exiting the hood, the air sweeps the hood’s contaminants, leaving you with a clean working area.
Before a laminar flow hood is rated as an ISO 5 environment, it has to live up to the stringent classifications. It is why an ISO 5 zone needs 240 to 360 air changes per hour to help maintain its cleanliness.
Zonsteel is a top brand when it comes to making high quality vertical laminar flow hoods. You can buy them today knowing they would maintain the features of class 100 or ISO 5 clean area.
How Does The Vertical Laminar Flow Hood Work? Is it Effective?
Figure 3 How a Vertical Laminar Flow Hood Works
The vertical laminar flow hood works by pushing the room air into the system past the HEPA filter using a fan. The HEPA filter is crucial for removing up to 99.99% of the particles in the air before it is forced down into the work area.
Since the fan filter unit is placed on the top of the vertical laminar flow hood, it becomes easier to direct airflow downwards. This also reinforces the effect of gravity; thus, it is easier to achieve quick results.
The air sweeps across the work area and exits from the front panel. This leaves you with a clean working area to use for various applications.
Looking at whether it is effective or not, we find it is ideal for various applications. It is why the vertical laminar flow hood remains a popular option.
What is the Purpose of the Primary Filter in the Vertical Laminar Flow Hood?
Any system containing a HEPA filter will always have a primary filter. The reason is that the primary filter is important for removing the large particles that might otherwise end up clogging the HEPA filter. As such, this will largely improve the overall lifespan of a HEPA filter.
Since the primary filter would be trapping the large particles, it is best if you replace it more often to prevent dirt from accumulating in the system.
The HEPA filter is also Part of the Vertical Laminar Flow Hood. How Can You Maintain It?
Since HEPA filter is important in a vertical laminar flow hood, it is important to know how best to maintain it.
It is advisable to replace the HEPA filter rather than cleaning it. However, sometimes it is still possible to clean the HEPA filter to continue using it.
Before you can clean the HEPA filter, there are a few things to keep in mind. Make sure that your filter can be washed. It is why you can get most HEPA filters being marked as washable or permanent.
A washable HEPA filter for a vertical laminar flow hood is one that can be cleaned by rinsing it under cold water. Make sure not to touch the filter material. Also, you have to allow it to completely dry before installing it into the vertical laminar flow hood.
There will be some special instructions to consider too. Always look at what Zonsteel recommends on the maintenance of the HEPA filter.
If you find the filter marked permanent, then you can only clean it gently using a vacuum cleaner. The vacuum cleaner will suck away as much dust and debris as possible. Such filters should not be exposed to water.
Now that you know how to maintain the HEPA filter ensure that your vertical laminar flow hood is always in the right working condition.
