What You Should Know About Horizontal Laminar Flow Hood?
The laminar hoods are mainly used for producing sterile airflow. The direction of the flow of the air is also important.

A laminar hood is a complete set-up that describes the flow pattern of the air. If you are having a lab set up then you may have to regulate the flow direction of the air in the room. In the cleanroom set-up as well, this movement is important. If the airflow direction is not correct then it can fail the experiment during the testing stage. This is why most lab settings may make use of laminar flow hoods.

A simple type of flow hood is a horizontal or vertical setup. The set-up will help in maintaining the right direction of the airflow. So if you want the air to flow only in one particular direction, then you will have to install the laminar hoods. So if there are critical processes that are performed in the cleanroom then you will use a laminar flow hood.

Why is the hood so useful?

This is more like what are the uses of the hood in the workstation. The hood is a term that is technically used for bench setup. The bench may have different areas bifurcated as the workstations. These are mainly divided into upper and lower workstations. The flowing movement can easily be maintained so the work environment is more sterile.

If you are performing substance testing in the upper area then the toxins will not be allowed to flow till the lower area of the hood. Such types of workbenches are more useful for lab settings. The same setups can also be used for PCR applications.

The process of working of the laminar flow hood

The laminar hoods are mainly used for producing sterile airflow. The direction of the flow of the air is also important. The device will help in producing the streams of air. The specialized HEPA filter units are used for producing the air streams. The direction of the air stream is maintained parallel.

The pressurized air is allowed to flow through the hood. This produces the turbulence effect. So the unit performs well if it maintains a steady circulation of the air streams indoors.

Well-engineered units

The hood is a perfect piece of engineering. The quality of the hood may depend on the type of engineering techniques it uses to regulate the direction of the air stream. The air handling system has to be very efficient.

If the unit does not have an effective air handling system, then it may not be much effective.

Simple maintenance

The airflow hood unit that you select for the workstation has to be simple in design. It should also be easy to clean and maintain. The filter unit should not be a complex design. If the design is complex, then cleaning the filter unit very often may not be easy.

You also need to ensure that you have a select unit that is durable for your workplace. All types of units may not be the same.

Efficient HEPA filter units

The Horizontal Laminar Flow Hood unit is installed with a quality HEPA filter unit. This type of filter unit guarantees a 95 % success rate. It helps filter all microbes as well from the air. The unit that you select should have a quality and certified HEPA filter installed.

You can look around for more effective devices that make use of filter unit that is 99.9 per cent effective as well it depends on the workplace where the unit will be installed.

Select ideal bench class

The moment you have to install these units in the workstations, you will have to choose from amongst the three most popular classes. These types of benches are classified as Class 1, 2 or 3 types. If you need an extra level of protection then you need to select a bench class 3 type.

The best benefit of using class 3 type benches is that they will help filter out all types of pathogens as well. Any type of microbe allergens can also be filtered out.

In case you are installing the hood, you should not store any harmful chemicals in the rear part of the hood. Always ensure that you have left sufficient space for the air to circulate. If the filters are blocked then the efficiency of the hood will also be lower.

Any type of modifications should not be done for the hoods. If you want to make changes then it is advisable to hire the technical team. Horizontal hoods are designed to work for selected room dimensions. They have a fixed workstation where the flow of the air will be regulated.
