RE: Air flow in modular cleanroom environment
Air filtration is used in cleanrooms to minimize particulate in the cleanroom environments’ air. Particulate removal is achieved by transporting the particles with air through highly efficient particulate air (HEPA filters) or ultra low particulate air (ULPA) filters. The filters remove up to 99.99% of the particulate in the air. The classification of a modular cleanroom environment is largely based on the amount of particulate in the air. The particulate is measured in microns. The amount of microns in your environment is typically determined by the criticality of the production or process that is happening in the modular cleanroom environment.
