cleanroom engineering

2025-10-14

Cleanroom engineering is the specialized field focused on designing, building, and maintaining controlled environments with extremely low levels of airborne particles. It involves engineering systems for airflow, filtration, temperature, humidity, and pressure to meet strict cleanliness standards for industries like pharmaceuticals, microelectronics, and biotechnology. Key tasks include performing architectural, mechanical, and electrical calculations, selecting appropriate filters (like HEPA or ULPA), and ensuring regulatory compliance.

Key aspects of cleanroom engineering

Design and construction:

Engineers create the overall layout and structure, including architectural, mechanical, and electrical systems, to meet specific cleanliness classifications (e.g., ISO 14644-1).
Air filtration and HVAC:

A critical component is the installation of high-efficiency particulate air (HEPA) or ultra-low particulate air (ULPA) filters to remove contaminants. The heating, ventilation, and air conditioning (HVAC) systems are carefully designed to control airflow, temperature, humidity, and pressure.
Contamination control:

Beyond air quality, the design addresses contamination from people and materials by incorporating features like air showers and requiring staff to wear specialized clothing.
Regulatory compliance:

Engineers ensure the facility meets stringent industry standards, such as those from the FDA and Good Manufacturing Practices (GMP).
Validation and commissioning:

The final stage involves testing and certifying that the cleanroom operates as designed and meets all specifications, from initial construction through to the start-up and approval phases.

Industries that use cleanrooms

Pharmaceuticals, Biotechnology, Microelectronics and semiconductor manufacturing, Aerospace, Food production, and Research laboratories.
