Designing a Class 1000 Cleanroom

Key Considerations and Components

Designing a Class 1000 Cleanroom, also known as ISO 6, is a complex task that requires meticulous planning and execution to maintain strict cleanliness standards. These cleanrooms are vital across industries such as biotechnology, pharmaceuticals, and microElectronics, where controlling contamination is crucial. This guide outlines the design aspects, material considerations, and systems integration necessary for a compliant and efficient Class 1000 cleanroom.

Functional Layout

The functional layout of a Class 1000 cleanroom dictates efficiency and flow within the space. Designing an effective layout involves strategically planning the placement of equipment, workstations, and pathways to minimize contamination risks.

Zoning: Divide the cleanroom into zones based on cleanliness requirements, ensuring that high-risk activities are isolated from less sensitive tasks.

Construction Material Selection

Selecting appropriate construction materials is vital to the cleanroom's integrity and cleanliness.

Component	Material Requirements
Wall Panels	Constructed from non-porous materials like coated steel or aluminum, which are easy to clean and resistant to chemicals.
Ceilings	Should be made from durable materials capable of supporting HEPA filter units, often utilizing a suspended grid system for easy access and maintenance.
flooring	Requires seamless and anti-static materials, such as epoxy or vinyl, to minimize particle generation and electrostatic discharge.
Cleanroom Equipment	Equipment should be made from non-shedding materials like stainless steel to maintain hygiene and durability.

Laminar vs. Turbulent Flow

Class 1000 Cleanrooms can utilize either laminar or turbulent airflow.

Laminar Flow

Provides consistent, unidirectional air movement, ideal for environments requiring stringent air cleanliness.

Turbulent Flow

Suitable for areas where air cleanliness needs are less rigorous but still require efficient particulate removal.

Modular Construction

Modular construction presents a flexible and scalable approach to cleanroom design, allowing for easy reconfiguration and expansion as needs evolve.

Flexibility and Maintenance: Modular systems streamline construction and maintenance processes, reducing downtime.

Airflow and Pressure Control

Maintaining precise airflow and pressure control is critical for preventing contamination ingress and ensuring particle removal.

Positive Pressure: Essential for keeping contaminants out, achieved by maintaining higher internal pressure compared to adjacent areas.

HVAC Integration

An effective HVAC system is central to controlling the cleanroom environment, managing temperature, humidity, and air cleanliness.

Temperature and Humidity Control: Consistent control prevents conditions such as condensation, which could compromise sensitive processes.

HEPA Filtration

HEPA filters are the backbone of cleanroom filtration, capturing 99.97% of particles that are 0.3 microns or larger.

Filter Efficiency: Ensures air purity, meeting the cleanliness levels required for a Class 1000 cleanroom.
