Testing of Horizontal Laminar Flow Cabinet

What is Horizontal Laminar Flow Cabinet?

The Horizontal Laminar Flow Cabinet is an enclosed workspace that uses filters to remove all the excess particles entering the cabinet to create a contamination-free work environment.

Laminar means the direction of the flow is in one direction with almost zero or minimum turbulence.

In a laminar air flow hood, the velocity of airflow remains between 0.3m/s to 0.5m/s. The sample is protected from airborne contamination.

It is so designed to prevent any type of contamination of biological samples or bacteria. The processed air is passed through the FFU HEPA filters which carefully extract all the contaminated airborne particles to make a safe and sterile environment in the lab.

These workstations although are not suitable for the operator to some extent but ensure the protection of the product that is under examination.

What is the Working Principle of Horizontal Laminar Flow Cabinet?

The Horizontal Laminar Flow Cabinet works on the basic principle of unidirectional flow of the air through the cabinet.

By using one or more HEPA filters present in the cabinet, this device creates a particulate-free surrounding through an inwardly flowing air stream.

Laminar airflow is achieved by passing air through a filter system before directing it across a work surface.

Filter pads or pre-filters allow for a smoother flow of air into the cabinet after the air is passed through the filter pad.

Blowers and fans then direct air toward HEPA filters. Bacteria and other contaminated particles are ultimately trapped in these HEPA filters so that air moving through the system is particulate-free.

Most of the effluent air then passes over the working bench as it exits the cabinet toward the operator’s face, passing through perforations present at the bottom of the cabinet.

To prevent outside air contaminants from entering the cabinet, the Horizontal Laminar Flow Cabinet is enclosed on both sides and has constant positive air pressure.
