What is the Working of a Flow Cabinet?
A Flow Cabinet is designed for clean rooms and different other applications requiring a sterilized environment.
To provide the controlled environment for specimen protection, the cabinet works in the following steps:
The basic principle at which the cabinet works is the supply of air with laminar airflow for capturing all of the contaminants.
The air comes from outside the environment and enters inside the cabinet first by passing through the pre-filters that are adjusted at the top of the cabinet.
Pre-filters makes sure the capturing of all larger-sized particles, dust, and debris from air to shield the HEPA filter from dust accumulation.
Air enters inside the cabinet after passing from pre-filters. The blowers or the fans that are integrated below the filter mediate the air directed towards the HEPA filter and spread it all over the Flow Cabinet.
After that, the air will be entered into the HEPA filter. The HEPA filters will ensure the capturing of air-borne particulates and contaminants as bacteria, viruses, and fungal spores, etc.
The air moving out after filtration will be free from contaminants and all other impurities.
The effluent air will be discharged out from the cabinet simply by passing over the working bench and moving out towards the operators’ face.
Some amount of air is also discharged through the perforated rare side of the cabinet.
The sides of the cabinet are closed to maintain the positive pressure of the Flow Cabinet. The positive pressure protects the entry of outside air towards the cabinet from the sides.
The process will remain to continue with air processing until the work will be completed. After the end of working, clean out the cabinet and turn on the UV lights for sterilization of the cabinet for the next operation.
