USA ISO 5 Modular Cleanroom Project for High-Precision 3D Printing Manufacturing
2026-06-30
Medical imaging equipment such as CT scanners depends on ultra-precision components that must be manufactured in contamination-controlled environments. Even microscopic airborne particles can affect cathode filament assembly, laser welding quality, vacuum sealing, and ultimately the performance of the finished CT tube.
Instead of constructing an entire cleanroom, many manufacturers choose a mobile ISO Class 5 laminar flow hood to create a localized clean environment exactly where contamination-sensitive processes take place.
For one of the world's largest CT equipment manufacturing facilities in Beijing, Airkey engineered a customized mobile laminar flow hood that delivers ISO Class 5 cleanliness while allowing flexible deployment within an active production line.
Airkey designed and manufactured a customized Mobile Laminar Flow Hood for a leading medical device manufacturer specializing in CT imaging equipment.
The solution provides localized ISO Class 5 protection for precision assembly and laser welding processes without interrupting existing production operations.
Location: Beijing, China
Industry: Medical Device Manufacturing
Application: CT Tube Production
Cleanliness Level: ISO Class 5 (Class 100)
Area: 7㎡
Internal Height: 2.4 m
Model: LAF-E35-S03 (3.6×2-P)
The project demonstrates how modular clean air technology can improve manufacturing quality while reducing installation complexity.
The customer is GE Medical Systems (China) Co., Ltd., one of GE Healthcare's largest global manufacturing bases for medical imaging equipment.
Its Beijing facility manufactures CT scanners, X-ray systems, detectors, and X-ray tubes that are exported to more than 100 countries worldwide. Maintaining contamination-free production is essential for ensuring product reliability and meeting international medical device quality standards.
CT tubes contain highly sensitive precision components manufactured at micron-level tolerances.
Dust particles adhering to tungsten filaments or cathode assemblies can lead to unstable electron emission and increase product rejection rates.
Laser welding and vacuum sealing processes are equally demanding. If airborne particles become trapped in the weld seam, they may create microscopic leaks that compromise the ultra-high vacuum required inside the CT tube, making the product unusable.
These challenges require continuous vertical laminar airflow that protects critical workstations from airborne contamination throughout the manufacturing process.
To address these manufacturing challenges, Airkey supplied a fully customized mobile laminar flow hood capable of delivering stable ISO Class 5 clean airflow directly over critical production stations.
The modular structure allows installation without cutting or welding inside the factory, minimizing disruption to ongoing production.
Heavy-duty FOOTMASTER caster wheels enable operators to relocate the unit whenever production layouts change, providing greater manufacturing flexibility than conventional fixed cleanrooms.
Transparent anti-static strip curtains surround the working area to reduce external airflow disturbance while maintaining excellent operator visibility.
The hood also includes factory-installed DOP test ports, allowing routine HEPA filter integrity testing throughout the equipment lifecycle.
Unlike permanent cleanroom construction, localized laminar flow technology delivers clean air exactly where it is needed.
The system uses vertical unidirectional airflow to continuously remove airborne particles from critical assembly areas while reducing operating costs compared with maintaining an entire ISO Class 5 production room.
Because the equipment is modular and mobile, manufacturers can quickly adapt production lines for new products or changing workflows without major facility modifications.
Before shipment, every Airkey laminar flow hood undergoes comprehensive testing, including HEPA leak testing, airflow velocity verification, cleanliness validation, illumination measurement, and overall performance inspection to ensure compliance with ISO 14644 standards.
A mobile laminar flow hood creates a localized ISO Class 5 environment around contamination-sensitive processes while avoiding the higher construction and operating costs of a full cleanroom.
Critical manufacturing steps such as precision micro-assembly and laser sealing often require ISO Class 5 clean air protection to reduce particle contamination and improve product consistency.
