The envelope uses smooth,non-particle-shedding,non-particle-harboring metal panels.All internal corners are coved(rounded)for easy cleaning.Panel joints are sealed to prevent ingress of external contaminants.A ceiling grid system holds HEPA/ULPA filters,creating unidirectional or mixed airflow.Material selection is strictly controlled to avoid particulate-generating materials.

Cleanliness classes range from ISO 1 to ISO 8,depending on industry needs.Positive pressure is maintained indoors to prevent backflow from less clean areas.It requires a high-precision constant temperature and humidity HVAC system.Floors are typically epoxy terrazzo or PVC sheet,offering wear resistance,anti-static properties,and seamless surfaces.Lighting uses cleanroom-specific fixtures.
Semiconductor and IC manufacturing and packaging;LCD panel production;sterile production,filling,and packaging in pharmaceuticals;medical device manufacturing and packaging;biological labs;and high-precision component storage in aerospace.It is essential infrastructure for high-tech manufacturing.
