The Critical Role of Partition and Ceiling Systems in Cleanrooms
Cleanroom partition and ceiling systems serve as the fundamental infrastructure that enables precise environmental control in contamination-sensitive operations. These systems are not merely physical barriers but engineered solutions that actively contribute to maintaining cleanroom classifications.
Functional Significance
- Containment and Zoning
- Create controlled environments with defined ISO classifications
- Establish physical separation between different cleanliness zones
- Enable proper pressure cascades (typically 10-15 Pa
- Airflow Management
- Provide structural support for HEPA/ULPA filtration systems
- Facilitate laminar or unidirectional airflow patterns
- Minimize turbulent air currents that could redistribute particles
- Material Compatibility
- Constructed from non-shedding, cleanable materials
- Resistant to disinfectants and sterilization processes
- Meet electrostatic discharge (ESD) requirements where applicable
Partition System Specifications
Core Design Features
Feature | Technical Requirement | Purpose |
