The production of optical fiber—the backbone of modern data transmission technology—requires an environment free from microscopic contaminants that could compromise signal integrity and product performance. Even particles invisible to the naked eye can scatter light signals, increase attenuation, and render high-speed communication cables unusable.
In fiber optic manufacturing, cleanroom facilities enable contamination-free processing of high-quality components for demanding applications, including telecommunications, medical devices, aerospace, and quantum computing. Even microscopic dust particles can become embedded in the glass during the drawing process, creating scattering centers that degrade optical performance.
Project Specifications: Tailored for Optical Fiber Innovation
Application: Optical fiber research and production
Cleanroom class: ISO 6 (Class 1,000)
Dimensions: 8m (L) x 5m (W) x 3m (H)
Key features: High glass windows, cassette ceiling-mounted air conditioners, flush-mounted air return panels, personnel air shower, material pass-through
Compliance: Fully engineered to meet ISO 14644-1 cleanroom standards
Smart Layout Design for Contamination Control
The cleanroom layout was strategically designed to ensure strict separation of personnel flow and material flow, a fundamental requirement for cross-contamination prevention in sensitive optical fiber manufacturing.
Change room: Personnel must pass through this controlled gowning area before entering the cleanroom, ensuring proper hygiene protocols.
Personnel air shower: High-velocity HEPA-filtered air removes particles from garments before entry into the main cleanroom.
Material pass-through: A dedicated pass-through chamber allows safe transfer of materials between the cleanroom and outside without compromising the internal environment.
Main cleanroom: ISO 6 environment for optical fiber research and production operations.
This logical separation ensures that personnel and materials follow distinct, non-intersecting paths, significantly reducing contamination risks critical for fiber optic technology.
Innovative Design Features for Optimal Performance
-
High glass windows for unobstructed visibility
Unlike traditional solid-wall cleanrooms, this facility features floor-to-ceiling high glass windows on all walls, providing:
Complete visibility: Researchers and supervisors can observe operations from outside without entering, reducing traffic and contamination risks.
Natural light transmission: Creates a more open, less claustrophobic working environment.
Educational demonstration: Ideal for research facilities where process observation is valuable for training and collaboration. -
Cassette ceiling-mounted air conditioners for worker comfort
To ensure a comfortable working environment for researchers spending extended periods inside the cleanroom, cassette ceiling-mounted air conditioners were installed:
Space-efficient design: Mounted flush in the ceiling, saving valuable floor space.
Even air distribution: A 360-degree airflow pattern ensures consistent temperature throughout the room.
Quiet operation: Minimises noise disturbance for focused research work.
Precise temperature control: Maintains stable conditions essential for optical fiber production processes.
-
Flush-mounted air return panels for energy efficiency
Four custom-designed flush-mounted air return wall panels are strategically installed to:
Connect to FFU system: Panels connect directly to fan filter units (FFUs) to recirculate conditioned air.
Energy conservation: By recirculating rather than exhausting conditioned air, the system significantly reduces HVAC energy consumption.
Space optimisation: Flush mounting eliminates protruding columns, maximising usable floor space.
Seamless appearance: Creates smooth, cleanable wall surfaces ideal for cleanroom hygiene.
Advanced Airflow Management
The combination of cassette AC units and flush-mounted return panels creates an efficient airflow pattern:
Supply air: Cassette units deliver conditioned air from the ceiling.
Workstation coverage: Air flows through the critical optical fiber research areas, removing contaminants.
Return path: Air is drawn into the flush-mounted return panels at low levels.
Recirculation: Return air travels through FFUs for HEPA filtration before being recirculated.
This closed-loop system maintains ISO 6 cleanliness while minimising energy costs—a critical consideration for long-term operational sustainability.
Factory Pre-Assembly & Testing: Guaranteed Performance
Before shipment to Mexico, the complete modular cleanroom was assembled in Airkey's facility and subjected to rigorous Factory Acceptance Testing (FAT):
Airflow velocity and uniformity tests: Ensuring proper coverage and laminar flow characteristics
HEPA filter integrity scanning: Verifying filter performance and seal integrity
Room pressure differential verification: Confirming proper pressure cascades between rooms
Particle count testing: Certifying ISO 6 classification compliance
This proactive testing eliminates on-site performance surprises and dramatically accelerates the client’s commissioning and validation timeline upon delivery.
