What is a Cleanroom?

A cleanroom is a controlled environment that adheres to strict standards for cleanliness, air quality, and temperature. It is typically defined by its level of cleanliness, measured in terms of the number of particles per cubic meter. The most common classifications are ISO 1 to ISO 9, with ISO 1 being the cleanest.

Key Features of Cleanroom Environments

• Controlled Air Quality: The air within a cleanroom is filtered to eliminate particulate matter.
• Temperature Regulation: Maintaining a consistent temperature is critical for processes sensitive to thermal fluctuations.
• Humidity Control: Humidity levels are closely monitored and regulated to prevent moisture-related issues.
• Materials Used: Construction materials like aluminum are often used due to their durability and ease of cleaning.
