A cleanroom is a controlled environment that is maintained with special filters, ventilation systems, and other equipment to keep the level of pollutants at a minimum. This is a sterile environment designed mainly for manufacturing, research, and other activities that require precision, high-level cleanliness, and low levels of particles, dust, and microorganisms. Cleanrooms are also a standard in the field of biotechnology, aerospace, pharmaceuticals, and medical equipment. In this article, we will explore what a cleanroom is, its features, uses, and how it works.


Why do we need a cleanroom?


A pharma clean room is designed to limit particle contamination from both outside and inside the environment. In simple words, a cleanroom is a room with a specific level of contamination control. Such controlled environments are essential for research, manufacturing, and other activities in the field of biotechnology, aerospace, and medicine. When it comes to a clean manufacturing process, even the slightest contamination can cause disastrous results in the finished product's quality.


How does a cleanroom work?


Cleanrooms work via a combination of airflow control, room pressurization, and filtration. The air flowing in and out of the room does not enter the cleanroom directly; instead, it passes through a series of filters before reaching its destination. These filters are designed to catch particles that would otherwise cause contaminations, and the airflow itself is controlled to ensure it circulates through the room without creating turbulence that could disturb particles on surfaces or in the air.


Features of a cleanroom


Cleanrooms are designed with several unique features that help keep the space clean and contamination-free. These features include:


1. Special airflow systems: Cleanrooms have specific ventilation systems that flush the air out frequently to reduce the level of pollutants in the air. These systems draw air from outside the cleanroom, passes it through a series of filters, and then delivers the cleaned air back into the environment.


2. Surface Materials: surfaces are smooth and easy to clean, making it easy to maintain a clean environment. The walls, ceiling, and floor are all designed to minimize static buildup and impede the accumulation of particles.


3. Pressure control: Cleanrooms are designed with high levels of pressure to prevent the entry of contaminants. The pressure difference between the inside of the cleanroom and outside the room discourages air and other particulate from entering the controlled space.


4. Sterilization: Cleanrooms have a sterilization process that ensures that all equipment, surfaces, and areas remain free from contamination. Typically, cleanrooms use chemicals or ultraviolet radiation to sterilize surfaces and pharma machinery.


5. Clothing and Personal Protective (PPE): Personnel who work in a cleanroom have to wear specific PPE such as gloves, masks, and gowns to reduce contamination risk.


Typical applications of cleanrooms


Cleanrooms have diverse uses in several industries. Some of the most common applications of cleanroom include:


1. Biotechnology: Cleanrooms are used by biotech companies for the production of drugs, medical pharma machinery, and electronic devices. Precision and control are essential in the biotechnology industry to prevent contamination that could alter the product performance or risk human safety.


2. Aerospace: Cleanrooms are used in aerospace to manufacture spacecraft, satellites, and other electronic devices used in space travel. Such equipment needs to be free from contamination, so using a cleanroom is paramount.
