Clean rooms are defined as specially designed, constructed, environmentally controlled enclosed spaces or rooms. It is specially designed and built with controlled airborne particulates, temperature, humidity, air pressure, airflow patterns, air motion, vibration, noise, viable living organism, and lighting.

Particulate control includes:

• Particulate and microbial contamination
• Particulate concentration and dispersion

Federal Standard 208E or ISO 14644-1 defines a clean room as a chamber in which the concentration of airborne particles is controlled to specified limits.

PROJECT CATEGORIES

Today, many manufacturing processes require that spaces be designed to control particulate and microbial contamination while maintaining flexible installation and operation costs. Clean rooms are typically used in manufacturing, packaging, and research facilities. These are some of the projects for our clients in different industries.
