Cleanrooms create and maintain completely controlled clean environments, typically with positive air pressure. Our fabric Cleanroom enclosures range from non-spec’d “E” or environmental rooms (also known as white rooms or grey rooms) to fully specified class 100, 1000, 10 000, or 100 000 air cleanliness. Modular in design and custom-designed to meet your specific material handling and process specifications, Soper’s SoftWall fabric Cleanroom enclosures are easily integrated with third party fan and filter modules.
