Air Flow Cabinet: An Ultimate FAQ Guide

Millions of particulate agents are constantly floating in the air. These agents are mainly responsible for the contamination of our surroundings and the tasks we are performing.

It is because particulate agents may have microbes (fungi, bacteria, viruses, etc.), that can replicate and hinder the quality of controlled processes being carried out.

For this reason, an Air Flow Cabinet is a must-have for any lab unit or controlled environment for smooth conduction of the controlled processes.

It maintains the cleanliness of the environment, equipment, and specimen to comply with the hygienic standards necessary for working in labs and clean rooms.

It filters the contaminated air and recirculates it within the working area to protect the sample from pathogens and maintain high sterile conditions for the process conduction.

What is an Air Flow Cabinet?

An Air Flow Cabinet is ISO Class 5 equipment that works in positive pressure conditions to offer a clean work area for providing a particulate-free environment for controlled applications.

It offers maximum product protection by offering a clean and sterile environment using a primary filter (also called pre-filter) and the main filter (ULPA or HEPA filter).

It features steel construction with epoxy powder coating for avoiding rusting and corrosion problems during the process conduction.

You can also get negative-pressure models with 304L stainless steel construction customized depending upon the requirements of your applications.

It is basically divided into two main types: the horizontal and the vertical units, available in different models and varieties.

An Air Flow Cabinet is not the same as a biological safety cabinet because it only protects the products from contamination, whereas a safety cabinet protects the user also.

  • Prevention of surface microbial contamination.
  • Inhibition of long-term growth of microbes of the surface.
  • Maintenance of particulate-free working conditions.


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

The difference between a Horizontal and a Vertical Air Flow Cabinet is given below in detail:

Horizontal Air Flow Cabinet:

As the name says, it is involved in the horizontal direction of the HEPA-filtered air, starting from the back of the cabinet to the front area throughout the work area.

From the airflow workers settle downstream which increases their chances of potential exposure to the contaminants.

This is why these cabinet models are not suitable to be used for applications requiring the involvement of highly toxic chemicals or infectious biological materials.

Horizontal Air Flow Cabinet offers a high level of protection to lab samples and materials from airborne particles because the hands and gloves of the workers are directed downstream from the flow of the air current.

It also decreases the work surface turbulence and is most suitable for applications involving the use of smaller equipment as larger equipment cause airflow disruption.


Vertical Air Flow Cabinet:

It aligns the direction of air (after passing through the HEPA filter) towards the workbench from where it moves out through the front opening or the work surface holes.

This downward airflow direction is safe for the laboratory environment and the workers and is used in applications like drug preparation, parts assembly, media preparation, or electronic device inspection. It also comes with low turbulence features due to its vertical design and configuration.

In a vertical airflow cabinet, the filter is installed on the top offering more workspace to the user and is suitable for applications requiring larger equipment.

Vertical Air Flow Cabinet

Vertical Air Flow Cabinet

How is the Vertical Better than Horizontal Air Flow Cabinet?

A Vertical Air Flow Cabinet is better than a Horizontal Air Flow Cabinet in the following ways;

Less Turbulence Production:

You can efficiently perform your operation on the work surface of the Vertical Air Flow Cabinet model because of its low turbulence production.


More Work Space:

A larger workspace allows easy and convenient handling of the application equipment and samples. Due to the top location of the filter installed a vertical model provides you with more room to carry out the performance.


Large Equipment Usage:

A vertical unit is preferable when dealing with large equipment and materials.


How is the Advanced Air Flow Cabinet Better than Standard Air Flow Cabinet?

What are the Airflow Directions in the Air Flow Cabinet?

The direction of the airflow in the horizontal laminar flow cabinet includes taking the air from outside the cabinet for filtration and then directing the filtered air from the backside of the unit in the direction of the operator’s face.

This is why you must not use this when your processes involve hazardous or toxic materials that if struck on the user’s face, can prove to be harmful.

In the vertical laminar flow cabinet, the air is filtered from the outer portion of the cabinet. The air is then recirculated and filtered from inside the cabinet. In this configuration, the filtered air travels down from the top.

This downward flow is advantageous in providing protection to the operator as well as the product, which is possible due to efficient air recirculation in the entire working space. The most preferred equipment for plant tissue culturing procedures is the Horizontal Air Flow Cabinet.

This directs the airflow over the working surface and also throws out all the contaminants from the controlled environment. These procedures don’t involve the usage of toxic or hazardous materials, so horizontal configuration is suitable.

But in case hazardous materials are involved, you should use the vertical configuration, which will be costly but will surely protect your operator.


What is the Use of Microprocessor Controllers in an Air Flow Cabinet?

Microprocessor controllers are featured with updated integrated management methods of all major functions related to filtration and ventilation.

The main features of the microprocessor controller of the Air Flow Cabinet include:

  • Self-regulation of the entire ventilation and filtration system components
