In the intricate world of manufacturing and scientific research, precision and control are paramount. The smallest particle or contaminant can compromise sensitive processes, leading to product defects or skewed research results.
To mitigate these risks, industries ranging from semiconductor manufacturing to pharmaceuticals heavily rely on a specialized space known as a Cleanroom Environmental Control Area. To establish and maintain a cleanroom, you need careful planning, design and construction.
This article delves into the fundamentals of cleanroom environmental control and its classifications. Alongside, we’ll also explore what you need to build a cleanroom while maintaining the highest standards of quality and reliability.
A cleanroom is a controlled environment that maintains a low level of pollutants such as dust, airborne microbes, aerosol particles, and chemical vapours. The primary purpose of a cleanroom is to create and sustain an environment where the concentration of airborne particles is controlled within specified limits.
These controlled conditions are crucial for industries where minute particles can significantly impact the quality of products or outcomes of experiments.
Cleanrooms are classified based on the level of cleanliness they maintain, which is determined by the number and size of particles allowed per cubic meter of air. The classification system is standardized and adhered to globally, ensuring consistency in cleanroom design and operation.
The International Organization for Standardization (ISO) and the United States Federal Standard 209E are two commonly used standards for cleanroom classification. Here are the classes of a cleanroom.
The ISO classification system uses the number of particles per cubic meter to define cleanliness. The cleanroom classes range from ISO 1 (the cleanest) to ISO 9 (the least clean).
Each class has a corresponding maximum allowable particle count, and the classification becomes stricter as the class number decreases. For example, an ISO 1 cleanroom allows a maximum of 10 particles per cubic meter, while an ISO 9 cleanroom allows up to 1,000,000 particles per cubic meter.
The Federal Standard 209E classification system was widely used in the United States until it was replaced by the ISO standards. It categorized cleanrooms from Class 1 (cleanest) to Class 100,000 (least clean). The transition to ISO standards was mainly to align with global practices and achieve standardization.
Cleanroom Components and Design Solutions
Establishing and maintaining a cleanroom requires careful planning, design and construction. Each component and design element is vital in reaching the desired cleanliness levels. Here are some key cleanroom equipment:
The heart of any cleanroom is its air filtration system. High-efficiency particulate air (HEPA) and ultra-low penetration air (ULPA) filters are commonly used to remove particles from the air. You should place these filters strategically to ensure optimal air circulation and particle removal.
Heating, ventilation, and air conditioning (HVAC) systems are tailored to the specific needs of cleanrooms. These systems control temperature, humidity, and air circulation, contributing to the overall cleanliness and comfort within the controlled environment.
Personnel working in cleanroom controlled environment must wear specialized cleanroom apparel, including coveralls, hoods, gloves, and shoe covers, to minimize the introduction of contaminants. The apparel varies based on the cleanroom class and the sensitivity of the processes you’re conducting.
The materials used for cleanroom walls and flooring must minimize particle generation and facilitate easy cleaning. Smooth, non-porous surfaces are preferred to prevent the accumulation of contaminants.
Seals and Gaskets
Seals and gaskets protect cleanroom environments from outside contamination. They help keep out dust, pollen, bacteria and debris that might enter through doors, windows or any other openings in a facility. Maintaining proper seals between doors or windows or openings within the facility is paramount to keeping an airtight environment within.
Cleanroom technology has applications across multiple industries where precision and contamination control are key elements. Some notable sectors that utilize cleanroom technology extensively are:
The semiconductor industry relies heavily on ultra-clean environments to produce microchips. Minute particles in the atmosphere can create defects in final products when in the production environment. Therefore, cleanrooms are critical in guaranteeing the reliability of electronic devices.
Cleanrooms are integral to pharmaceutical and biotech research and manufacturing environments. They help ensure drug purity and compliance with regulatory standards while also producing safe products that adhere to safe practices.
The aerospace and defence industries utilize cleanrooms for the assembly and testing of sensitive components, such as satellite electronics and precision optics. Cleanroom technology ensures the reliability and performance of these critical systems.
Cleanrooms are integral in healthcare facilities, particularly compounding pharmacies and research laboratories. Their sterile conditions aid the production of medications as well as sensitive experiments.
