Introduction to Clean Rooms
A clean room is a controlled environment designed to minimize the presence of airborne particles, aerosol particles, and other contaminants. These specialized spaces are essential in various industries, including pharmaceutical manufacturing, medical device manufacturing, and electronics manufacturing, where stringent control of environmental parameters such as temperature, humidity, and air pressure is crucial. High-Efficiency Particulate Air (HEPA) filters play a vital role in removing particles from the air, ensuring that the environment remains as clean as possible. Additionally, the final filtration of air occurs at the point where it enters the cleanroom, and achieving a minimum of 20 air changes per hour is essential to meet cleanliness standards. Air changes per hour (ACH) are meticulously regulated to prevent contamination and maintain the integrity of the clean room.
Clean rooms are classified based on their level of cleanliness, with ISO 8 being the second lowest cleanroom classification. Despite this, ISO 8 clean rooms are still significantly cleaner than typical office environments, making them suitable for various industries that require a controlled environment to prevent contamination and ensure product quality. Selecting the appropriate cleanroom classification is crucial and depends on factors like process requirements and air quality. The use of HEPA filters, along with precise control of air changes, helps maintain the required cleanliness levels, making clean rooms indispensable in industries where even the smallest particles can compromise product integrity.

Specifically, in medical device and pharmaceutical manufacturing, clean rooms, product safety, and quality are crucial. If too many particles enter the space, raw materials, manufacturing processes, and finished products will be affected. Therefore, clean rooms are essential in some industrial manufacturing areas that require precision machining.
Temperature Control in ISO 8 Clean Rooms
Temperature control is a critical aspect of maintaining a clean and controlled environment in ISO 8 clean rooms. The ideal temperature range for an ISO 8 clean room is between 19-23 degrees Celsius (66-73 degrees Fahrenheit), with a setpoint around 20-21 degrees Celsius (68-70 degrees Fahrenheit). ISO 8 cleanroom classification and standards emphasize particle count requirements as outlined by US Federal Standard 209E and ISO 14644-1, highlighting the significance of maintaining low particle counts in environments such as pharmaceutical and medical device manufacturing. Temperature fluctuations can cause employees to shiver or sweat, leading to more particles being released into the cleanroom, which can compromise the quality of products and increase the potential contamination risk.
To maintain a stable temperature, temperature control systems such as air conditioning and heating systems are employed. These systems work in conjunction with high-efficiency particulate air (HEPA) filters and air pressure control systems to ensure a controlled environment. HEPA filters are particularly crucial as they help remove airborne particles that could otherwise contaminate the clean room. It is also important to set humidity alarm delays to accommodate fluctuations during normal operation such as cleaning or opening doors.
In addition to preventing contamination, temperature control is essential for preventing microbial growth. This is particularly important in pharmaceutical manufacturing and medical device manufacturing, where maintaining the integrity and sterility of products is paramount. By ensuring the clean room remains within the ideal temperature range, manufacturers can prevent contamination and ensure the quality and safety of their products.
Humidity Control in ISO 8 Clean Rooms
Humidity control is another essential aspect of maintaining a clean and controlled environment in ISO 8 clean rooms. The relative humidity (RH) in an ISO 8 clean room should be maintained between 30-60%, with a setpoint around 40-50%. Humidity control systems, such as humidifiers and dehumidifiers, are used to maintain a stable RH level and prevent contamination. Additionally, the manufacturing of softwall cleanrooms, which comply with ISO classifications and standards, is crucial for catering to different cleaning requirements and maintaining controlled environments.
High humidity levels can lead to microbial growth, which poses a significant risk to product quality and safety. Conversely, low humidity can cause static electricity, which can damage sensitive equipment and products. Therefore, maintaining an optimal humidity level is crucial for preventing contamination and ensuring the quality of products. Meeting regulatory requirements for humidity control is essential to prevent contamination and ensure product quality.
Humidity control is particularly important in industries such as pharmaceutical manufacturing, medical device manufacturing, and the production of food and beverage products. In these industries, maintaining a controlled environment is essential to prevent contamination and ensure product safety. Additionally, proper humidity control helps maintain a comfortable working environment and prevents the growth of airborne microbes and aerosol particles.
By implementing effective humidity control systems, manufacturers can ensure that their ISO 8 clean rooms remain within the required humidity range, thereby preventing contamination and ensuring the quality and safety of their products.
