What are the Basic Components of a Laminar Air Flow Cabinet?
The main components of the Laminar Air Flow Cabinet are given below:
The cabinet is smooth and flawless with no joints to mitigate the residence area of microbes. The cabinet protects the streamlined airflow pattern.
The outer side of the cabinet is made of glass that can be opened entirely or in two openings for putting hands inside the cabinet for working.
The working site of the cabinet is called work station. All of the required material for processing is placed on a workstation as burners and culture plates. The surface of the workstation is also made of stainless steel to resist corrosion.
Pre-filters are also called filter pads. These are integrated on the topside of the cabinet from where air enters. It traps the dust particles as well as microbes and provides a streamlined airflow pattern to air.
Blowers or fans are integrated at the below side of the filters. These blowers take the air and spread it inside the cabinet. These also direct the air towards the HEPA filters for cleaning.
Mostly UV-C lamps are used to kill the germs inside the cabinet. These lamps ensure the sterility of the cabinet.
But UV radiations are dangerous for humans. So make sure to turn on the UV Lamps 15 minutes before working so that all of the germs may kill until you get ready for work.
The fluorescent Lamps are fitted inside the Laminar Air Flow Cabinet to provide the normal lighting for performing the whole process.
The incoming streamline air passes from the HEPA filters that dissipate all of the particulates from the air ensuring sterility of the whole unit.

How is a Horizontal Laminar Flow Cabinet Different from Vertical Laminar Air Flow Cabinet?
It is designed for the attainment of a sterilized environment. According to the direction of airflow, it is divided into Vertical Laminar Air Flow Cabinet and Horizontal Laminar Air Flow Cabinet as given below:
Horizontal Laminar Air Flow Cabinet
- In this cabinet, the air enters from the outside environment to the inside cabinet from the rear side of the workstation.
- After air entrance, the blowers enforced the air towards the HEPA Filters for the removal of dust and all other airborne particulates.
- The filtered air after circulation moves out from the cabinet as discharging air and dissipates in a horizontal flow pattern at a workstation.
- The horizontal laminar airflow is always parallel to the workstation that is beneficial to clean the environment at continuous and constant air velocity.
- But its drawback is that discharged air directly moves out towards the operator resulting in the mitigation in its protection rate.
Vertical Laminar Air Flow Cabinet
- In a vertical laminar flow cabinet, the direction of the air is from the top side of the cabinet to the bottom side that is vertical to the workstation.
- The air is also drawn towards the HEPA Filters by blowers or through the fans for filtration.
- The workbench in vertical cabinets does not require more space, not depth. This makes an easiness in vertical airflow without making any hurdle in downstream airflow.
- The discharged air does not pass over the workbench as in horizontal cabinets but it vertically moves downward.
- One of its benefits is that it does not dissipate the air directly towards the workers’ face limiting its side effects on human health.
Horizontal Laminar Air Flow Cabinet
How is a Laminar Air Flow Cabinet Different from Biosafety Cabinet?
- A biosafety cabinet is designed to protect the specimens and other material from contamination by outside air.
- Recirculation of the airflow pattern is configured inside the cabinet to deal with airborne particulates.
- Discharged air is dissipated from the cabinet through the exhaust hood present on the top side of the cabinet.
- Both the material and the operator remain safe while working in the biological safety cabinet.
Laminar Air Flow Cabinet
- It is also used for material protection and aseptic specimen distribution under controlled conditions as compared to outside contaminated environments.
- A laminar airflow pattern is followed inside the cabinet that is directed to dissipate instead of recirculation as in safety cabinet class 2.
- There is no biological safety hood to discharge the air from the laminar cabinet but instead, some of the air discharged out from rare perforation but a high amount of air discharged out directly contacting with operators face.
- Only specimen is remained protected inside the Laminar Air Flow Cabinet, not operator as compared to the biosafety cabinet.
