For communication satellites that remain within earth’s orbit, an ISO Class 6-8 cleanroom allows sufficient particle and contaminant control. Cleanroom engineers design each space so that particles from production surfaces are whisked away from critical components. A combination of softwall production areas and hardwall cleanroom facilities provide isolation of critical tasks. Depending on the level of particulate controlled required, a softwall cleanroom may be deployed for mobile transport, while a modular hardwall cleanroom provides dedicated HEPA filtration in the most critical areas.

An ISO Class 8 environment is about 10x cleaner than average room air. For the most critical satellites, those that will journey the far reaches of outer space, cleanroom conditions require air quality that is roughly 100,000x cleaner.
