Cleanroom technology is a rapidly expanding market, driven by increasing demand from the pharmaceutical and biotechnology industries, medical device manufacturers, and hospitals.
Valuates’ report states that the global market for cleanroom technology is predicted to grow from US$12.1 billion in 2021 to US$16.9 billion by 2028, with a compound annual growth rate (CAGR) of 4.9% during the forecast period of 2022-2028.
In the quest to create a controlled environment for manufacturing or research, two popular options are hardwall clean rooms and softwall clean rooms. Both types of clean rooms are designed to maintain a sterile and dust-free environment, but the question remains: which one is better suited for your application?
In this article, we’ll compare the two types of clean rooms and help you make an informed decision.
What are Hardwall Clean Rooms?
Hardwall cleanrooms, as described by American Cleanroom Systems, utilize HEPA fan filter units to clean the air inside the cleanroom effectively. These types of cleanrooms can range from class 100 to class 100k or ISO-5 to ISO-8 cleanroom classification.
Many hardwall cleanrooms are modular in design and use negative pressure plenums to achieve a recirculating system that incorporates air conditioning. Hardwall clean rooms are constructed using rigid materials, such as aluminum or steel, and have solid walls and ceilings.
They typically have a higher level of air filtration and are better suited for applications that require a more controlled environment. Because of their high level of cleanliness, hardwall cleanrooms are commonly used in industries such as electronics, pharmaceuticals, and medical device manufacturing.
What are Softwall Clean Rooms?
Softwall clean rooms, on the other hand, are typically constructed using flexible materials such as vinyl or polyurethane. Their walls and ceilings are designed to be easily assembled and disassembled.
These clean rooms have a lower level of air filtration and are often used for applications that require a clean environment but not the same level of control as hardwall clean rooms. Softwall clean rooms are commonly used in industries such as food and beverage, cosmetics, and research.
One of the main advantages of softwall clean rooms is their versatility, as they can be easily expanded to meet changing needs or moved for convenient access. Plus, these cleanrooms come in a range of standard sizes, starting from 4 feet by 4 feet and going up to 24 feet by 36 feet. This variety in sizes makes them versatile and capable of accommodating different applications.
Cost Comparison
While softwall clean rooms are initially cheaper due to their lower material and maintenance costs, hardwall clean rooms have a longer lifespan and can prove to be more cost-effective in the long run.
Hardwall clean rooms are constructed with sturdy materials such as aluminum or steel, which allows them to withstand harsher conditions and last longer. This makes them a better investment for companies that require a controlled environment for their operations.
Additionally, the higher level of air filtration in hardwall cleanrooms can lead to fewer contaminants and improved product quality.
Installation and Maintenance
Softwall clean rooms are easier to install and disassemble than hardwall clean rooms. They require minimal tools and can be assembled quickly, making them ideal for applications that require a temporary clean room. However, softwall cleanrooms require more maintenance and cleaning due to the flexible materials that can wear out and collect dust.
Hardwall clean rooms require more time and effort to install, but they are sturdier and have a longer lifespan. They also require less maintenance and cleaning than softwall clean rooms, making them ideal for applications that require a permanent clean room.
Air Filtration and Contamination Control
Hardwall cleanrooms typically have a higher level of air filtration and can provide a more controlled environment. They are designed to keep out contaminants and maintain a stable environment for sensitive manufacturing processes. Softwall clean rooms have a lower level of air filtration and are less effective at controlling contamination.
However, softwall clean rooms are still effective at preventing dust and other particles from entering the room. They are suitable for applications that require a clean environment but do not need the same level of control as hardwall clean rooms.
Conclusion
In summary, both hardwall and softwall cleanrooms have their advantages and disadvantages. Hardwall clean rooms are better suited for applications that require a high level of contamination control and a more stable environment, while softwall clean rooms are ideal for applications that require a clean environment but do not need the same level of control.
Ultimately, the decision of which type of clean room to use will depend on your specific application and requirements. If you need help deciding which type of cleanroom is best for you, consult with a professional cleanroom manufacturer who can provide expert advice and assistance.
