A Class 100 cleanroom, also known as an ISO 5 cleanroom, is a highly controlled environment designed to minimize airborne particle contamination. It achieves this through the use of HEPA (High-Efficiency Particulate Air) filtration systems. The "100" designation refers to the maximum allowable number of particles of 0.5 micrometers or larger per cubic foot of air.
Understanding Class 100 Cleanroom Standards
- Particle Count: The defining characteristic is a maximum of 100 particles (0.5 µm or larger) per cubic foot of air. This exceptionally low particle count makes it suitable for highly sensitive applications.
- HEPA Filtration: High-Efficiency Particulate Air (HEPA) filters are crucial. These filters remove at least 99.97% of particles 0.3 micrometers in size and smaller, significantly reducing airborne contamination.
- Construction: Class 100 cleanrooms can be constructed using various materials and methods, including softwall (flexible) or hardwall (rigid) structures. The choice depends on the specific application and budget.
- Applications: These cleanrooms are essential in industries requiring extremely low contamination levels, such as:
- Medical device manufacturing: Ensuring sterility and preventing contamination of medical devices.
- Pharmaceutical production: Maintaining product purity and preventing cross-contamination.
- Semiconductor manufacturing: Protecting sensitive components from dust and other particles that could impact performance.
- Examples of Equipment Used: Specialized equipment is often used within Class 100 cleanrooms, including HEPA vacuums, cleanroom wipes, and specific cleanroom-compatible clothing to prevent contamination.
The use of Class 100 cleanrooms is not limited to these examples. Many other industries benefit from their stringent cleanliness standards. The design and construction of a Class 100 cleanroom are tailored to the specific needs of the application.
