How Does a Horizontal Laminar Air Flow Work?

A Horizontal Laminar Air Flow uses the main laminar airflow principle for working. It has HEPA filters that start an inward airflow to establish an environment free of contaminants.

This air passes a filtration system to get filtered and then it is spread around the work surface, involving the given steps:

1. Firstly, this air crosses a filter pad or a pre-filter which generates a streamlined airflow into the system.
2. Then the fan or the blower pushes this air into the HEPA filter box.
3. These filters grab the dirt, debris, bacteria, and other particulates and pass out particulate-free air.
4. A major part of this air passes through the working bench, while some part of it enters the perforations present at the base of the unit.
5. The maintenance of positive air pressure in this Horizontal Laminar Air Flow is important to not allow contaminated air from outside the environment to enter it.

What are the Different Classes of a Horizontal Laminar Air Flow?

Three main classes of a Horizontal Laminar Air Flow include:

Class 1

The Horizontal Laminar Air Flow Class 1 is the simplest class, which has a structure similar to the chemical fume hood.

It is safe for the environment and as well as the operator. But a drawback of this class is that it is not safe enough to prevent contamination of the work samples

Class 2

The Horizontal Laminar Air Flow Class 2 is extremely beneficial for contamination that can result from hazardous substances. It not only protects the lab samples and the workers but also sterilizes the working area.

Class 3

The Horizontal Laminar Air Flow Class 3 works excellently for achieving the highest level of cleanliness and also aids in establishing air-tightness in the environment.

This class is most suitable when dealing with human pathogens or even when working for infectious substances.

Horizontal Laminar Air Flow Class 3

What is the Difference Between Vertical and Horizontal Laminar Air Flow?

A laminar flow cabinet comes in the following two types, on the basis of the airflow pattern present in it:

Vertical Laminar Air Flow:

The floor space of this cabinet does not need to be larger in size as its hood is not much deeper.

The air does not directly blow at the operator and a barrier on the face of the operator is provided by a sash.

It is quite easy to access the filter present on the top. Processing equipment or large air striking objects have an amount of turbulent effect. Items placed on the work surface experience less to no contamination.

For large or tall equipment greater working height is needed.

There is a requirement for overhead clearance. A ladder can be needed for servicing the units or changing filters.

Items cannot be stacked over each other as they can impede the airflow in your sterile room.

Horizontal Laminar Air Flow:

This sort of air cabinet reduces or eliminates the turbulent effects caused by the vertical airflow as this is parallel to the work surface.

These turbulent effects strike perpendicularly to the work boundary.

Staggering and positioning sterile materials and equipment that are closer to the filter becomes quite easy in the Horizontal Laminar Air Flow.

Gloves and hands are downstream of the sample so usually, they are less contaminating. They are considered as the agents that contaminate less as they are said to be at the sample downstream.

Things to Consider

• In the case of rear access repositioning of filter, service is usually required.

• Samples that are larger in size are more likely to impede airflow and this can become a reason for contamination of downstream samples.

• Sash is not mandatory for using this equipment.

• It can blow powder or fumes to the face of the operator.

Difference Between Vertical and Horizontal Laminar Air Flow

What are the Components of a Horizontal Laminar Air Flow?

The operation of a Horizontal Laminar Air Flow is produced due to a combination of components, each playing its specific part:

Working Station

To make all processes run smoothly, there is a working station in the unit. This working station has loops, burners, and culture plates.

For the prevention of steel from getting rusted, the worktop needs to be made up of stainless steel.

Cabinet

Steel is the key manufacturing component of the cabinet, but the steel should be stainless having no joints or gaps. This sort of arrangement prevents the accumulation of spores.

Inner environment insulation is provided in this type of airflow and protection of the Horizontal Laminar Air Flow against the outer environment is also ensured.

A glass shield is present in the front of the cabinet. Some models have two openings of the glass shield (so that hands of the user can conveniently enter into the working area).

Filter Pad

A filter pad is present on the top through which the air passes into the system. The role of this filter pad is to provide a passage to air for passing inside the Horizontal Laminar Air Flow.

Furthermore, some microbes and dust particles in the air are trapped into the filter and prevented from going inside the equipment.

HEPA Filter

The HEPA filter refers to a High-Efficiency Particulate Air filter, it functions as a primary filter, for making the environment sterile so that operation is carried out conveniently.

The air that was filtered earlier with a filter pad now passes through this filter to trap more dust particles, bacteria, and fungi.

The probability of the Horizontal Laminar Air Flow getting contaminated is reduced by using this filter as it ensures complete sterilization.

Fan

A fan is present below the filter pad that sucks in the air and moves it around in the whole Horizontal Laminar Air Flow.

Air is also allowed to move towards the direction of the HEPA filter by the fan filter unit for trapping the remaining microbes.

UV Lamp

Before any of the operations begins the Horizontal Laminar Air Flow is sterilized by an ultraviolet germicidal lamp.

However, it is required to turn on the UV lamp fifteen minutes earlier, so that the user’s body does not get exposed to the UV rays.

Fluorescent Lamp

This product needs some sort of light so that the operation is performed conveniently. This light source is provided by the fluorescent lamp.

Applications of Horizontal Laminar Air Flow

When is a Horizontal Laminar Air Flow Required?

Worksurface does not require a greater amount of turbulence. Vertical and horizontal, both of the cabinets are likely to produce less turbulence.

However, the horizontal one has a marginally lesser flow of turbulence as the air cannot hit any obstacle unless it exits the fume hood, while vertical flow hits the unit bottom.

An increase in turbulence is expected using equipment larger in size, then you can use this product.

Contamination needs more attention and needs to be controlled efficiently.

This product provides more protection against contamination as the gloves and hands are arranged downstream to the sample.

How to Maintain your Horizontal Laminar Air Flow?

A Horizontal Laminar Air Flow requires the observance proper maintenance schedule followed by professional technicians. This maintenance involves:

Minimize the Clutter:

This item is not designed for storage purposes. So, the clutter existence hinders the flow throughout the area of work.

Additionally, clutter creates problems for cleaning the work surface.

Washing of Arms and Hands Before Entering

Though there are normal and ultraviolet filters to prevent contamination, it can still enter via personnel and touching the sterilized products.

For that reason, washing your hands properly is extremely significant as hands can have numerous bacteria.

For maximum protection, hands should be washed before and after leaving the workbench.

Arrangement of Objects for Obtaining Benefits Fully

Arranging items properly plays a role in providing clean air and work area. As everything is cleaned via filters, the arrangement of items should be in such a way that everything is used easily without any inconvenience.

The usage of squirting solutions and sprays on the filters should be avoided. To prevent the air from getting contaminated, nothing should be in contact with a HEPA filter.

Wraps and outer pouches on the work surface edge need to be removed. Since these kinds of pouches and wraps are not sterilized they can bring pollutants to the workbench.

They can also be thought of as clutters and can disrupt the pattern of airflow.

Objects that are larger in size should be kept away from the back part of the system. Because large objects can pollute other items and disrupt the pattern of airflow which is responsible for removing the contaminants from the work area.

Activities like talking, movements, and coughing should be kept to a minimum in the main area of work.

Because talking and coughing can lead to the release of particles which then cause contamination and can disrupt the airflow.

In case if talking is extremely important, it should be done away from the work area. The user should disinfect all the materials before he disinfects the materials. Only sterilized materials are allowed in the area.
