What Is the Difference Between ISO 5 and ISO 8 Cleanroom?
Created on 01.23
When it comes to cleanroom environments, ISO 5 cleanrooms and ISO 8 cleanrooms are two commonly used classifications based on the cleanliness level they provide. Understanding the difference between these two cleanroom types, and how FFU cleanroom systems and modular cleanrooms can impact performance, is critical for industries such as pharmaceuticals, electronics, food processing, and biotechnology. This article explores the key differences between ISO 5 cleanrooms and ISO 8 cleanrooms, highlighting the role of modular cleanrooms, FFU cleanroom systems, and the benefits of selecting the right cleanroom for your specific applications.
Key Differences Between ISO 5 Cleanroom and ISO 8 Cleanroom
The main difference between ISO 5 cleanrooms and ISO 8 cleanrooms lies in their allowed particulate concentration, air filtration, airflow design, and the industries they support.
ISO 5 Cleanroom
ISO 5 cleanrooms provide the highest level of cleanliness and are typically used in critical industries that require low contamination. These cleanrooms allow a maximum of 3,520 particles/m³ (≥0.5 microns) in a cubic meter of air, and are essential for processes like:
Semiconductor manufacturing
Pharmaceutical production (sterile filling)
Aseptic environments for medical device production
In ISO 5 cleanrooms, FFU (Fan Filter Units) or ULPA filters are typically used to achieve consistent air cleanliness levels. FFU cleanroom systems ensure that the airflow is precisely controlled, maintaining an ultra-clean environment. High-efficiency HEPA filters are used for additional particle filtration, ensuring optimal protection for highly sensitive processes.
ISO 8 Cleanroom
ISO 8 cleanrooms, on the other hand, allow up to 3,520,000 particles/m³ (≥0.5 microns) of air, which is suitable for less critical applications where cleanliness is still important but contamination control requirements are lower. Common applications for ISO 8 cleanrooms include:
Non-sterile pharmaceutical manufacturing
General laboratory environments
Food production facilities
Medical device assembly
Modular cleanrooms are often the preferred choice for ISO 8 cleanroom configurations. These modular cleanrooms offer easy installation and flexibility, making them a cost-effective solution for industries that require controlled environments but not to the stringent levels of ISO 5 cleanrooms.
Airflow and Filtration Systems in ISO 5 and ISO 8 Cleanrooms
Both ISO 5 and ISO 8 cleanrooms require robust air filtration systems, but the level of filtration and airflow control differs significantly.
FFU Cleanroom Systems in ISO 5
In ISO 5 cleanrooms, FFU cleanroom systems play a crucial role in maintaining the cleanliness of the environment. FFUs use high-efficiency filters to continuously supply clean air, maintaining a laminar flow to prevent contamination from airborne particles. These systems ensure precise and stable airflow rates, which is critical for industries requiring stringent contamination control.
Modular Cleanrooms with HEPA Filters in ISO 8
In ISO 8 cleanrooms, modular cleanrooms are often employed to meet the necessary cleanliness standards while reducing operational costs. These modular systems are easier to install and can be configured with HEPA filters to control the level of particles in the air. The use of modular cleanroom designs also allows for scalability and flexibility in various environments, making them suitable for industries that don’t require the extreme cleanliness of an ISO 5 cleanroom.
Applications and Industry Suitability
ISO 5 Cleanroom Applications
ISO 5 cleanrooms are typically used in the most demanding applications:
Semiconductor fabrication: Controlling particle contamination is essential to ensure the precision of semiconductor components.
Pharmaceutical manufacturing: Sterile conditions are critical to ensure that drugs, medical devices, and vaccines are produced without contamination.
Biotech and research: The highest level of contamination control is necessary in biotech applications to protect experiments from contamination.
ISO 8 Cleanroom Applications
ISO 8 cleanrooms, while not as stringent as ISO 5, are still essential in several industries, such as:
Medical device manufacturing: Ensuring clean environments for the production of medical devices that don’t require the sterility of ISO 5.
Food processing: Maintaining a clean environment to reduce contamination without the need for extreme cleanroom standards.
General laboratory work: Laboratories that deal with non-sterile materials but still require basic contamination control for accurate testing.
Choosing the Right Cleanroom for Your Needs
When selecting a cleanroom, the decision largely depends on the cleanliness level required for your specific industry.
ISO 5 cleanrooms are ideal for high-precision, contamination-sensitive applications where even the smallest particle can affect outcomes.
ISO 8 cleanrooms are suitable for industries where cleanliness is necessary, but the highest level of contamination control is not essential.
Modular cleanrooms offer a flexible and cost-effective solution for both types of environments. Whether you're looking for an ISO 5 cleanroom for a semiconductor facility or an ISO 8 cleanroom for a food production line, modular designs allow for easy scaling and customization.
Conclusion
ISO 5 cleanrooms and ISO 8 cleanrooms serve different purposes, depending on the level of contamination control required. Whether you're working in high-tech semiconductor manufacturing or general laboratory operations, understanding these differences will help you select the most appropriate cleanroom solution for your needs. FFU cleanroom systems and modular cleanrooms provide excellent flexibility, fast installation, and reliable performance, making them ideal for a variety of industries and applications.
By choosing the right cleanroom classification, you ensure that your facility meets the required cleanliness standards and operational efficiency, all while adhering to industry regulations.
