puhdastiloille

Puhdastiloille, meaning "cleanrooms" in Finnish, refers to highly controlled environments designed to minimize the presence of airborne particles, dust, and other contaminants. These environments are essential for manufacturing and scientific research where even microscopic particles can compromise product quality or experimental results.

The key principle of a cleanroom is maintaining a specific air quality standard, measured by the number of particles per cubic meter of air. These standards are categorized using ISO classifications, with ISO Class 1 being the cleanest and ISO Class 9 being the least clean, comparable to a typical indoor environment.

Cleanrooms are characterized by specific design features and operational protocols. These include air filtration systems, such as HEPA (High-Efficiency Particulate Air) and ULPA (Ultra-Low Particulate Air) filters, which remove particles from the air. Airflow within the cleanroom is meticulously managed, often in a unidirectional (laminar) or non-unidirectional (turbulent) pattern, to sweep contaminants away from critical areas.

Personnel entering a cleanroom must adhere to strict protocols, including wearing specialized cleanroom suits, gloves, and masks to prevent shedding particles from their bodies. Equipment and materials introduced into the cleanroom are also thoroughly cleaned and decontaminated.

Applications for cleanrooms span various industries, including semiconductor manufacturing, pharmaceuticals, biotechnology, medical device production, and aerospace. The stringent control of the environment ensures the integrity and reliability of sensitive processes and products.
