ISO 14644-1 and older standard FS 209E determine class by the concentration levels of particles. The particles range in size from .1 -.5 microns (µm). The class defines a minimum cleanliness level, not a specific design. However class will greatly impact design considerations such as filtration, HVAC requirements and other design elements. Please call AdvanceTEC to discuss your specific requirements.
