A system that produces continuous, uniform air flow in both direction and velocity is known as laminar airflow. Unidirectional airflow is made possible in limited spaces by laminator air flow cabinets. They produce a particle-free working environment by expelling air across the work surface after it has passed through a filtering system.
Laminar Air Flow Cabinet Concept
They are containers made to circulate HEPA-filtered air at a constant speed and direction. This unidirectional laminar flow ventilation system for operating room helps to preserve sterility while avoiding cross-contamination.
What is the Mechanism of a Laminar Airflow Cabinet?
A laminar airflow cabinet's primary goal is to provide an atmosphere with sterile, filtered air. It employs the following components to carry out this action:
• Worksurface
• Enclosure
• fan and blower
• pre-filter and filter pad
• HEPA filter
• UV lamp
Together, these components form a laminar airflow cabinet. The blower aids the device's ability to draw ambient air from its top or front. The filter pad captures large airborne dust particles as the air passes across it.
You have the choice to disinfect the work area by using the UV lamp. The apparatus is meticulously built to maintain laminar airflow. The air inside the enclosure moves in one direction in straight lines parallel to one another.
Depending on the sterile hood's intended use, the airflow type may be vertical or horizontal. In a strict sense, it will protect both the sample and the user.
Advantages Of A Laminar Airflow Cabinet
The advantages of a laminar air flow for operating theatres will be discussed now.
• Easy to maintain: all that is required to clean the pre-filter when it becomes dirty is to wash it.
• Sustainable: doesn't discharge hazardous gas into the environment.
• Lightweight: 90% of laminar air flow cabinets are lightweight and have castor wheels on the bottom, making them portable. With these wheels, you can move them about with ease. They offer a sterile environment in which you can conduct research.
• Less costly: Compared to most other devices, a laminar airflow cabinet is less expensive.
Conclusion
When performing delicate work, a laminar airflow cabinet is an effective tool. It creates a clean environment inside the cabinet, allowing you to deal with delicate components like tissue culture and electronic wafers. Airflow cabinets are not only affordable and transportable but also a sustainable choice and light in weight. However, you must always wear protective lab attire while using the hood.
At the same time, you must follow the operating instructions. Additionally, it would help if you exercise caution while purchasing a cabinet for laminar airflow. Finally, consider your needs before selecting a type.
