Laminar Air Flow Hood: An Ultimate FAQ Guide

It is an enclosed hood that is specially designed for preventing contamination of biological samples, semiconductor wafers, or other particle-sensitive materials.

Laminar airflow is usually required by most of the contamination-sensitive environments as required in a Laminar Air Flow Hood.

This airflow works in the unidirectional sweeping of the particles, beginning from the cleanest area to the exit area.

In this case, the area under the hood is the cleanest whereas the vents along the bottom or back of the hood or the sash opening are the exit area.

Via the HEPA filter, the air is drawn inside and blown smoothly following a laminar flow pattern towards the user. The direction of the airflow helps in protecting the sample from the user.

But this does not ensure the protection of the user from the sample. A stainless steel hood construction is followed, free from any joints or gaps as these sites are significantly involved in heavy spore collection. You can get a Laminar Air Flow Hood in either vertical or horizontal configurations.

What is a Laminar Air Flow Hood?

A Laminar Air Flow Hood is prime quality and highly efficient device that supports control particle contamination.

The unidirectional air traveling at a constant speed, with least or no crossover of air streams (also referred to as lamina) is called laminar airflow.

It is opposite to the turbulent airflow in which the formation of eddies and swirls takes place which helps in the deposition of the particles randomly on the surfaces.

A Laminar Air Flow Hood has a special design that is responsible for ensuring that the upstream area will always be the cleanest area located closest to the filter face.

It also has a UV-C germicidal lamp that is helpful in sterilization of the interior as the contents before carrying out the procedure for preventing particulate contamination of the process.

Before starting your procedure turn these lamps on for at least 15 minutes

Once sterilized, switch off the light to limit eye and skin exposure to harmful UV as they are a leading cause of cataracts and cancer.

How Does a Laminar Air Flow Hood Work?

The laminar airflow inside this hood is the basis of its main principle. It has a clean and controlled environment free of contaminating particles, which is done by the inward airflow by the action of the single or multiple HEPA filters.

The incoming air travels through a precise filtration system and then enters the working surface after becoming the laminar airflow.

A pre-filter or filter pad present in the beginning receives this air and converts it into a streamlined airflow pattern in the hood’s controlled area. You can also use a medium filter.

This air then reaches the HEPA filters when pushed by the fan or the blower. These HEPA filters capture the bacteria, and dust particles to convert this particulate air into pure, clean, and filtered air.

This filtered air has two ways now, either it enters the working bench on its way to strike the user’s face. Or it may also enter through the perforations available at the lower surface of the hood.

Laminar Air Flow Hood is a properly enclosed system with a constant positive pressure of air strictly maintained. This pressure inhibits the entry of contaminated air particles into the hood’s controlled area.

 

How is a Laminar Air Flow Hood Constructed?

Initial Layering:

Two layers of plywood (3/4″) are used; one is 31-3/4″×31-3/4″ and the other is 20″×31-

3/4″.

Both the layers are glued together and then secured with screws. The two-layered thick table area undergoes a lamination process also.

Attaching the Filter:

From the table, the HEPA filter is set back at the thickness of the egg crate white panel (having rectangular cells for proper direction and diffusion of air).

The filter is held in shape by the space blocks. Machine screws help in securing the HEPA filter to the egg crate panel through the half-inch channel into the aluminum filter frame.

 

Building the Enclosure:

1″×12″ pine dado is used for building an enclosure around the HEPA filter for receiving the filter edges for making a better seal to sturdily hold the filter. This was followed by screwing the enclosure into the 3/4″ base.

 

Covering the Back:

1/4″ plywood is used for covering the back of the plywood.

 

Making the Top:

One continuous angle aluminum piece is used for making the 1/16″ thick 1″ angle aluminum frame for the plexiglass hood top.

At the corners, from the top side, a triangle is then cut out for making the 90-degree bends. The ends are then adjusted and secured in the 1/2″ channel.

What are the Major Types of Laminar Air Flow Hood?

According to the air flow’s direction, a Laminar Air Flow Hood is characterized into two different types: horizontal laminar air flow and vertical laminar air flow.

 

Horizontal Laminar Air Flow Hood:

This hood directs the air to the HEPA filters by the action of the blowers, this air is basically collected from the surrounding environment the filtered air enters the working area in a horizontal direction.

This hood is advantageous in a way such that the flow of air in a direction parallel to the working area is helpful in cleaning the environment with a maintained constant velocity.

But unfortunately, in this hood, the flowing air is finally directed towards the user’s face, which is not a safe option.

 

Vertical Laminar Air Flow Hood:

In this type of hood, the air movement is directed from the top portion to the bottom portion directly.

The working bench in this system doesn’t need to be that much deep and can be fitted in less space in contrast to the horizontal one.

Due to this, it is also easy to manage, has maximum air filter efficiency and there are minimum chances of airflow obstruction. Also, there is the least possibility of contaminated air movement downstream.

The best thing about Vertical Laminar Air Flow Hood is its safety, as it doesn’t target the face of the user for directing the blowing air.

Vertical Laminar Air Flow Hood

What are the Main Parts of a Laminar Air Flow Hood?

The major components that join together to form the Laminar Air Flow Hood are:

Main Body:

The main body of the hood is made using stainless steel, and the least gaps or spaces or even no gaps are present to limit the space where spores can accumulate and grow.

The purpose of this Laminar Air Flow Hood is to achieve insulation inside the controlled area and also to achieve protection from the external environment.

To easily take your hands inside this hood, a glass shield is present in the front portion. In some cases, this shield can be fully opened; however, sometimes, it has two different openings.

 

Work Surface:

To perform your procedures, there is a flat working surface present inside every Laminar Air Flow Hood.

You can easily place all your required equipment including the burner, culture plates, and loops on this surface so that you can easily access them when required.

In order to avoid rust and corrosion, stainless steel is most commonly used in constructing this work surface.

 

Pre-Filter:

A pre-filter or filter pad allows the air to pass through it and is installed in the upper portion of the hood.

Its purpose is to grab the dust and dirt particles from the flowing air and also to capture the microbes so that they disturb the internal control environment by reaching there.

 

Blower or Fan:

Under the filter pad, there is a powerful fan installed. The purpose of this fan is to consume the air and direct it into and around the hood.

This fan also sends the air towards the HEPA filter which acts as a primary filter so that final and precise trapping of microbes and leftover microbes can be done.

 

UV Lamp:

It is important to sterilize the materials, equipment, and the internal area of the Laminar Air Flow Hood before you start your procedure in it, and a UV germicidal lamp perfectly does this job.

To keep UV radiations away from the user, you can turn on this lamp 15 minutes prior to starting your procedure in it.

 

Fluorescent Lamp:

It is always essential to have a proper light supply inside the Laminar Air Flow Hood so that you can see everything clearly, and for this, you can install a bright fluorescent lamp.

 

HEPA Filter:

The High-Efficiency Particulate Air Filter is installed to sterilize the air flowing inside this hood, to assure a sterile room for the users and the procedures being performed.

After passing from the pre-filter, the partially filtered air enters this HEPA filter where dust particles, fungi, and other particulates are trapped.

This trapping decreases the chances of contamination that can be caused by the presence of microorganisms and harmful particles.

Why Use a Vertical or Horizontal Laminar Air Flow Hood?

Vertical Laminar Air Flow Hood:

A few reasons are listed below for selecting a vertical laminar flow cabinet for your application:

  • The hood is not very deep and it acquires little space for installation.
  • It can easily handle large or tall equipment due to its good working height.
  • Minimum turbulence is produced due to the collision of different large-sized objects.
  • The filter present on top is easy to access for cleaning.
  • Minimum chances of cross-contamination for the objects present on the working surface.
  • The air doesn’t strike the user’s face, for extra protection a sash is present.

Horizontal Laminar Air Flow Hood:

Given are some reasons to select a horizontal laminar flow cabinet for your application:

  • You can easily and simply arrange the required objects on the working station, closer to the filter.
  • Due to the downstream nature between the hands and gloves with the sample, they are less likely to get contaminated.
  • The laminar airflow is parallel in direction to the working station; this reduces the turbulence effects from the air flowing in the vertical direction, acting perpendicular to the working station.

 

Horizontal or Vertical Which Laminar Air Flow Hood is Best for your Application?

A Horizontal Laminar Air Flow Hood is useful in the following cases:

  • Both the horizontal and vertical units are excellent in producing minimum turbulent flow in the working area, but the horizontal one is a bit better in getting the least turbulence.
  • The air flowing in it doesn’t strike with any obstructing object until it gets out from the fume hood.
  • If you are dealing with small-sized objects or equipment during your process, there will be the least turbulence. However, in the case of large-sized equipment or objects, turbulence or disturbance in the normal airflow pattern will be produced.
  • This type of hood provides higher protection against contamination, because of the downstream placement of hands and gloves within the horizontal flow.

A Vertical Laminar Air Flow Hood is preferable in the following conditions:

  • If your procedure involves large equipment, you can use this vertical hood, due to its property of minimum turbulence production when dealing with large-sized objects.
  • Also, if the procedure you are performing requires the use of fine powders or soldering fumes, you can use this hood. It is safe to handle non-toxic powders present on or around the working surface. But it is better to use a chemical fume hood for this purpose.
  • The horizontal one is useful for tall and large objects because it has good height, due to the mounting of filters on the upper surface.
