  • Unistrutâ„¢ is used to create the overhanging frame for where the softwall cleanroom will go.
  • Threaded rod is then hung from the Unistrutâ„¢ . This is where the grid will be attached.
  • The Main Tees are hung perpendicular to the Unistrut to stabilize the grid. (not as shown in this photo).
  • Then Cross Tees are hung over the Main Tees to form a grid. T-Grid is used to stabilize the intersection of Main Tees with Cross Tees.
  • Populating the ceiling with HEPA Fan Filter Units determines what class cleanroom you will have. The more HEPA units, the higher the cleanroom class.
  • Finally softwall curtains are hung from the frame of the grid. Curtains are electronically welded into overlaps and then slid into the frame.

Take for example a manufacturer of precision optical lenses for a defense application that is plagued with dirt particles large enough to see with the naked eye. The particulates range in size from about 15-30 microns and number in the range of 5,000-7,000 per cubic foot. Utilizing the Clean Room Classification Chart, they can see that they would require an ISO6, Class 1,000 room to reduce the number of 15-30 micron particles to under 10 per cubic foot.
