Below is a list of Softwall Cleanrooms manufacturers from Rancho Santa Margarita, California. Soft wall clean rooms are atmospheric and climate-controlled enclosures used to conduct sensitive research, fabrication, testing and other processes. Unlike permanent, hard wall clean room systems, soft wall clean rooms feature plastic, often translucent strips suspended from a ceiling or other high point of attachment. They can also be enclosed by tightly-stretched fabric on a frame.
