Cleanroom Purification Engineering · Corridor and Partition Wall Systems

Modular cleanrooms are constructed from standardized cleanroom panels, aluminum profiles, and compatible hardware; compared to traditional masonry partitions, they offer shorter construction times, portability (allowing for disassembly and relocation), and flexible scalability. The enclosure utilizes double-sided color-coated steel cleanroom panels featuring smooth, non-porous, corrosion-resistant, and easy-to-clean surfaces; flooring options include self-leveling epoxy or sheet flooring, finished with coved skirting at the wall junctions. The ceiling layout integrates air supply and return terminals as well as sealed lighting fixtures—configured according to process requirements—to establish stable airflow patterns. Accessories such as doors, windows, pass-through boxes, and air showers are prefabricated in the factory and assembled on-site, thereby minimizing construction dust and reducing the time required for on-site installation.

Clean laboratories demand higher environmental stability than standard production workshops, requiring the control of airborne dust and microorganisms while ensuring safety during the handling of reagents and samples. The overall laboratory design centers on a cleanroom enclosure system, complemented by chemically resistant work surfaces, under-counter cabinetry, and specialized exhaust systems, effectively zoning the space into experimental areas, sample storage areas, and personnel corridors. Cabinets and work surfaces are constructed from acid- and alkali-resistant, easy-to-clean materials, with under-counter storage and workspace designed for convenience in daily use and maintenance. Laboratory furniture and enclosure components are custom-manufactured to uniform standards and installed on-site in a single phase, ensuring a cohesive aesthetic and consistent sealing performance.

The pass box serves as a dedicated channel for transferring materials, samples, and tools between clean and non-clean areas, enabling the exchange of items without compromising pressure differentials or introducing external contamination. The unit features a stainless steel housing with a smooth, crevice-free interior designed for easy cleaning and disinfection. Viewing windows on both the front and rear allow for easy monitoring of the items' status. The doors are equipped with seals and locking mechanisms, featuring an interlocking system that prevents both doors from opening simultaneously, thereby blocking direct airflow. All panels and frames feature rounded edges to prevent dust accumulation and minimize the risk of scratches.

An air shower serves as a mandatory purification checkpoint for personnel and goods entering a cleanroom. It operates by directing high-velocity, HEPA-filtered airflow from nozzles positioned on the sides and ceiling; this air dislodges and removes dust particles adhering to the body, work garments, and surfaces of items, thereby significantly reducing the contamination load upon entry into the clean area. The unit features a housing constructed from color-coated steel or stainless steel, with smooth, easy-to-clean interior walls. The nozzles on both sides are adjustable, and the floor consists of a perforated stainless steel grating to facilitate air return and cleaning. An interlocking system between the front and rear doors ensures the passageway remains sealed during the air shower cycle, preventing direct communication between the clean area and the non-clean area.
