Softwall cleanrooms use a simple steel frame structure to support flexible PVC curtains, typically cut a few centimeters above the floor to allow air to exhaust. These non-permanent cleanrooms operate at relatively low positive pressure and are generally used for lower cleanliness classifications such as ISO 6 to 8. Due to the reduced level of environmental control, precise temperature and humidity regulation is not normally provided.
Softwall cleanrooms are the most economical type of modular cleanroom construction and offer a flexible alternative to hardwall cleanrooms.
