Many workplaces like laboratories need a sterile and contaminant-free environment. Laminar airflow hoods do just that by steering the pollutants away from the workplace keeping the facility safe. By using laminar flow hoods, you will have an undisturbed supply of clean air in the workplace. These are designed mainly for mechanical and processing duties that are non-hazardous in nature.
How does a Laminar Flow Hood work?
A laminar flow workstation creates a sterile environment by getting rid of the pollutants employing a mechanism that is called unidirectional air stream. The mechanism utilizes HEPA filters to remove any impurities from the sir and then disperse it across the area. This creates a secure environment which is imperative for laboratories and for other workplaces too where the items used need to be protected from contamination.
The laminar flow hoods regulate the air flow at a constant speed, releasing a consistent composition of air. Generally, the hoods are equipped with two filters, the HEPA filter, and a pre-filter to filter the air effectively and protect the materials used and the products manufactured in the workplace.
Laminar air flow workstations which are equipped with energy-efficient HEPA filters offer 99.99% efficiency in filtering air, removing particles of up to 0.3 microns. The fans in these workstations often feature options to control its speed, allowing users to control the volume of air supplied to the workbenches. The fans are programmed to work quietly so that no disturbance is caused.
The pre-filters of the flow hoods can be snapped, making it much easier to maintain and repair them. To enhance the efficiency of the hoods, thick acrylic panels can be installed on the sides and on the rear of the workbench.
Where are they used?
Laminar air flow hoods are ideal for laboratories where equipment and materials that are delicate to particles and dust are used. The most common applications of these laminar hoods include medical facilities, electronics industry, circuit board manufacturing, medical devices manufacturing, semiconductor industry, glass tube manufacturing industry and other related industries and fields. For laboratories with special requirements, the laminar flow hoods can be customized too.
Types of Laminar Flow Hoods
Depending on the pattern of airflow, there are several types of laminar flow workstations. These cabinets and hoods can be manufactured as either horizontal or vertical or both. The horizontal laminar airflow workstations feature a horizontal air flow where the air shifts direction after originating from the top.
The vertical laminar air flow workstations, on the other hand, feature a vertical air flow where the dispersal takes place from holes in the foundation of the workstation. Though they both create a sterile environment, the vertical laminar flow hoods offer worker or operator safety as the air is dispersed from the bottom.
Both types of workstations can be customized according to the needs of the user with features like removable work surface, removable tops, lower shelves etc. Customization of these workbenches ensures that they meet your specific needs and work well within the environment.
No matter what type of laminar flow workstation you choose for your work environment, it should be able to provide a steady flow of clean and pollutant-free air. To ensure that the efficiency of the hood is not compromised, choose a renowned manufacturer that works in adherence with the necessary compliances and uses only high-quality materials. Variable fan speed, silent fan operation, and customization are key features to look for when buying a laminar airflow hood.
