An Overview of a Laminar Air Flow

 

Laminar Air Flow is an enclosed HEPA (high-efficiency particulate air) chamber with a filtered airflow system. Circulating unidirectional air, the chamber has nil turbulence maintaining a uniform velocity of around 0.3-0.5 m/s. Laboratories extensively use this equipment for maintaining a contamination-free environment in the workspace.

Let us look at its working

Laminar airflow can be either vertical or horizontal. The airflow system filters the air that moves within the defined space following uniform velocity and a particular direction.

How should you use the system?

Wipe the laminar airflow chamber. Sterilize the workstation surface by closing the workstation glass shield. Run the UV light for 15 minutes. The blower should be switched on for around 5 minutes before operation.

After sterilization open the sash and turns the fluorescent light.

Your chamber is ready for you to start with your experiments.

The principal function of the system is to eliminate all airborne contaminants ensuring that a sterile atmosphere is maintained. In microbiological studies, this equipment plays a very significant role in keeping the workstation aseptic.

After the air filter, the next most important component of the system is the air pad and fan that are critical for its working. The prefiltered air is suctioned by the fan/blower out of the filter pads that encapsulate the contaminants. This prefiltered air residual is made to pass through a high-efficiency particulate air filter that separates the contaminants. This can include fungus, spores, bacteria, and dust particles. Leaving behind a sterile environment in the work area where the air continues to maintain a uniform speed and direction.

Parts of the laminar airflow system

The enclosed cabinet system provides contamination-free air within the stainless-steel structure. The sterility inside the chamber is well protected from contamination outside. The glass sash is a sliding front door manually operated by users allowing you to open the window to the desired height that would be most convenient for the user to work within. Users can provide different operations and keep the culture plates, biological samples, blower, and materials inside with safety.

The filter pad comprises the primary filter or the pre-filter which sucks the room air. Placed on the top of the system, if the system is a vertical cabinet and at the bottom, if the cabinet is horizontal. In both cases, the filter pads trap room contaminants higher than or equal to 5 microns.

The function of the blower/fan is to draw the prefiltered air and send it in the direction of the HEPA filters. The blower is placed below the filter pad in the vertical system and next to the filter pads in a horizontal system.  

The HEPA filters can eliminate 0.3 microns particulates offering 99.9% efficiency and this is the final filtration that makes the condition sterile for safe operation.

The chamber is further sterilized with UV germicidal lamps which makes the Petri lamps, test tubes, cultures contamination-free. The UV lamp should be turned on 15 minutes before operation and switched off before work.
