Which of the following describes the types of cleanrooms?

The correct answer identifies the two primary types of airflow in cleanrooms: non-unidirectional and unidirectional.

Non-unidirectional cleanrooms, often referred to as conventional cleanrooms, maintain cleanliness by using recirculation methods, but they do not have a specific airflow direction. This means that particles can settle and accumulate because the airflow isn’t structured in a way that prevents this.

On the other hand, unidirectional cleanrooms, also known as laminar flow cleanrooms, utilize a specific direction of airflow to effectively sweep away contaminants. In these environments, air flows in a single direction at a constant speed to create a clean area by minimizing the potential for particulate contamination.

This distinction between the two types of airflow systems is crucial for different industries and applications, influencing how products are manufactured and how contamination is controlled. Understanding these categories helps in selecting the appropriate cleanroom design for specific processes and products, ensuring that cleanliness standards are met effectively.

Knowledge of cleanroom classifications can have a profound impact on operations in industries like pharmaceuticals, electronics, and biotechnology, where contamination control is critical for product integrity and safety.
