What are the Main Components of a Laminar Cabinet?

The major components of A Laminar Cabinet are explained below:


The cabinet is manufactured with stainless steel with no gap avoiding the spores collection.

By generating laminar flow inside and protecting it from the outer environment, the internal environment is insulated by the cabinet.

In front of the Laminar Cabinet, a glass shield is designed that contains two openings to put the operator’s hand inside the cabinet.

Working Station

All processes take place on a flat working station that is present inside the cabinet. Culture plates, loops, and burners are at the working station where all the procedures are carried out.

The worktop is corrosion-free because it is manufactured with stainless steel.

Filter Pad/ Pre-Filter

In the Laminar Cabinet, air enters through a filters pad into the cabinet that is located on the cabinet’s top.

Pre-filters or filter pads grasp all small and large dust particles from passing into the workplace within the cabinet.

Fan/ Blower

A blower or fan is located under the filter pad that pulls the air and rotates it everywhere in the cabinet.

The fan forces air in the direction of HEPA filters that stuck the small particles and microbes in the filters so that air remains germ-free.

UV Lamp

Laminar Cabinet also contains a UV germicidal lamp that is utilized to disinfect the inside of the cabinet before working.

Before starting the process, A UV lamp must be turned on to prevent it from exposure to UV to the user’s body.


Fluorescent Lamp

A Fluorescent lamp is utilized to deliver suitable light during operation and it is positioned inside the cabinet.

HEPA Filter

In the Laminar Cabinet, the HEPA filters are integrated with the cabinet that is utilized to sterilize the environment. Bacteria, dust particles, and fungi trap by the filters.

This filter makes sure that the environment inside the cabinet is fully sterilized. This decreases the chance of contamination.

How Does the Laminar Cabinet Work?

Working Principle

The working principle is the laminar airflow through the cabinet.

Step 1

The Laminar Cabinet begins its works by utilizing the inwards airflow that enters through one or more than one HEPA filter to generate a germ-free environment.

Step 2

A filtration system is used to take the air. First of all, the air enters through the pre-filter or filter pad that enables streamlined airflow into the cabinet.

Step 3

Next, the blower throws the air towards the HEPA filters.

Step 4

The HEPA filters grasp small particles, bacteria, and fungi particles when air passes through them. The major purpose of using a HEPA filter is to create germ-free air.

Step 5

Some of the waste air enters into holes that are located on the cabinet’s bottom rear end. Most of the air passes over a working bench. While it comes out of the cabinet it directs toward the operator’s face.

Step 6

The Laminar Cabinet is covered on the sides, therefore the positive pressure is kept constant to protect the interruption of polluted outside air into the cabinet.


What are the Main Types of Laminar Cabinet?

It is divided into two types according to the air-movement direction:

Vertical Laminar Cabinet

In the vertical laminar flow cabinet, the air enters from the top directly in the direction of the bottom of the cabinet.

Too much depth and floor space are not required in the vertical laminar cabinet as compared to horizontal which decreases the chance of obstacles and makes it more adaptable.

It considers safer because it doesn’t directly blow air the air on the operator who experiments.

Horizontal Laminar Flow Cabinet

The direction of the air is toward HEPA filters by using a blower that comes behind the working bench in the horizontal laminar cabinet.

One benefit of it is the flow of air that is parallel to the workplace purifies the environment with a constant velocity.

It is not a much safer device because air hits directly to the operator.

Horizontal Laminar Cabinet

What is the Main Function of Manometer in Laminar Cabinet?

A Magnehelic measuring device mounted on the rear work zone plate monitors the pressure difference between the laminar flow and the exhaust filter plenum.

This pressure gauge is a “Centre zero” type and acts as a pressure compensation indicator.

Careful laminar and exhaust fan velocity control to achieve airflow equilibrium between the two filter systems during testing to determine an effective air barrier and reported average laminar flow. It needs to be adjusted in stages.

The Magnehelic pressure gauge shows this pressure difference. Subsequent changes in the exhaust and laminar flow will lead to changes in the displayed pressure difference.

After the final set of fan speed control, the pointer on the Magnehelic display is set to the center “zero” position.

If this indicator shows a large movement from the central “zero” position while the cabinet is running, it indicates a malfunction and you should not use the cabinet until the fault is corrected.

Other displays and alarms provide additional information about the failure.

How Do HEPA Filters Work in Laminar Cabinet?

HEPA filters that capture submicron particles are a physical obstacle to protecting cabinets.

They contain highly fragile filter media, which could be easily broken by physical contact and decompose when exposed to liquids.

HEPA filters cannot be washed and are typically substituted if enhanced resistance to airflow affects cabinet performance, if extreme leak repair is required, or if severe surface uncleanness occurs.

Replacing the filters is appropriate for usage in serious applications and must be separately certified and tested in a NATA registered lab.

According to the BS3928 sodium flame test, the trap efficiency should be 99.997% or higher.

In addition, the filter must be proven to be complete (no pinhole leaks) according to AS1807.6.

Judging and installing the HEPA filter in the field is the most crucial test procedure for the cabinet. Do not use a Laminar Cabinet with doubted filter damage until the filter reliability has been tested.
