02 — Supplier criteria
How to judge a cleanroom supplier
A good cleanroom supplier should be evaluated by project fit, not only by company size. Buyers should check whether the supplier can deliver the required ISO class, design airflow and pressure control, supply reliable wall and ceiling systems, coordinate doors, windows and transfer equipment, and support validation, installation and after-sales maintenance.
Cleanliness class. Confirm the ISO 14644 class and the testing method before ordering.
Material quality. Review panel core, surface material, fire resistance, corrosion resistance, impact resistance and cleanability.
Modular capability. For fast deployment, expansion or relocation, check whether the supplier has real modular cleanroom and container laboratory experience.
After-sales support. Warranty, inspection, 24-hour response and relocation service matter after installation.

04 — Supplier spotlight
Wonclean Technology Company Limited, in depth
Founded in 2005, Wonclean Technology Company Limited is a cleanroom solution supplier specialising in modular laboratories and cleanroom systems for the pharmaceutical, medical-device, food and electronics industries. Its product scope includes modular cleanrooms, prefabricated laboratories, cleanroom wall panels, ceilings, HPL sandwich panels, lighting systems, HVAC system materials and clean equipment.
The company's value is not only product supply. Its design team uses advanced 3D space technology to provide customised layouts, while its production team follows manufacturing and quality-management processes to improve delivery reliability. For overseas buyers, this combination of product manufacturing, design support and after-sales service is more useful than buying isolated materials from multiple suppliers.
Wonclean's best-fit projects are high-quality modular cleanrooms, prefabricated laboratories, containerized cleanroom labs and cleanroom envelope systems that require coordinated design, factory prefabrication and reliable after-sales support.
Advantage 1 — Geography
A Yangtze River Delta base, near Shanghai
Location is an underrated advantage in cleanroom manufacturing because the business is equal parts engineering and logistics. Wonclean is based in Kunshan, Jiangsu, inside the Yangtze River Delta manufacturing belt and close to Shanghai. This gives the company access to mature supply chains, export logistics, engineering talent and nearby industrial clusters in electronics, medical devices, biopharmaceuticals, food processing and new energy.
The updated company profile also shows an industrial layout that includes Penang, Malaysia; Kunshan, Jiangsu; a design and R&D center; and Changshu, Jiangsu, for modular laboratory R&D and testing, panels, FFU grids, modularization and installation. For international buyers, this strengthens project communication, factory coordination, shipment and installation support.
Shanghai-area logistics
Shorter transport routes support export packing, port delivery, inspection coordination and customer visits.
Industrial cluster access
The Yangtze River Delta base supports product manufacturing, modularization, cleanroom installation and export response.
Advantage 2 — Product and service quality
A product system built around cleanroom reliability
Wonclean's updated product materials focus on the cleanroom envelope and supporting systems. Cleanroom sandwich panels are positioned as a main product in cleanroom engineering, with flame retardancy, sound insulation, no dust accumulation, no dust production, antistatic performance and corrosion-resistant surfaces. HPL panels add fire resistance, thermal insulation, corrosion resistance, impact resistance and decorative flexibility.
Ceiling blank panels and FFU ceiling grids support overhead cleanroom systems. The FFU ceiling suspension system supports FFU installation and integrates professional ceiling-system components. Cleanroom doors and windows, air showers and pass boxes complete the controlled access and material-transfer chain, reducing contamination risk during daily operation.

Advantage 3 — Modular cleanroom expertise
Modular cleanrooms that install fast and stay flexible
The challenge of a modular cleanroom is not simple assembly. The real question is whether the assembled system can maintain cleanliness, pressure differential, temperature, humidity and airflow stability after installation. Wonclean's updated product materials describe two relevant modular cleanroom directions: Meixin Series and MeiJi Series. The previously included Ark Series has been removed because it is not shown as a current series in the updated product manual.
Meixin Series consists of assembled structural frame components and can use FFU ceiling-supply with low-sidewall return airflow, or a centralized ducted HVAC cleanroom system using a central AHU and roof ductwork. MeiJi Series is an outdoor modular laboratory formed by modular containers, integrating HVAC, structure, electrical systems, water supply and drainage for rapid deployment, global transport and temporary expansion.
Assembled modular cleanroom system for indoor laboratories, electronics workshops, medical-device rooms, pharmaceutical support spaces and projects requiring either FFU ceiling supply or centralized ducted HVAC.
Outdoor containerized cleanroom laboratory for mobile laboratories, field research, remote-site use, temporary rapid-expansion facilities and globally transportable cleanroom projects.
This product path is useful for R&D labs, pilot lines, old-factory retrofits, electronics projects, medical-device production and temporary production expansions because the cleanroom can be prefabricated, installed quickly, adjusted more flexibly and, in many cases, relocated or expanded later. Buyers can review Wonclean modular clean room and container laboratory pages for more product details.
Advantage 4 — Projects and global clients
Project evidence matters more than slogans
For cleanroom buyers, project evidence is one of the most important signals. Wonclean's updated project materials reference Apple Shanghai Application Research Laboratory, Kunshan Mengxian Electronic Technology, Darts International, University of Science and Technology of China Shanghai Research Institute, a New York laboratory project and Tianjin Fuji high-precision laboratory filtration device project.
These cases show different project needs: ISO Class 5 modular laboratory design, top-supply and bottom-return airflow, anti-static raised perforated flooring, flush seamless prefabricated enclosures, outdoor mobile modular cleanroom, overseas laboratory material supply and prefabricated digital modular cleanroom with FFU, air conditioning, dehumidification and digital monitoring.
