The modular ceiling air‑supply system adopts standardized prefabricated modules, which are fully assembled and tested in‑factory. On‑site installation only requires hoisting, fixing and duct connection, with no on‑site component splicing or assembly needed. Construction procedures are cut by over 60 %, which greatly shortens project lead time. Standard modules are compatible with mainstream cleanroom dimensions, supporting flexible splicing and combination for workshops of varying sizes and cleanliness classes. Non‑standard customization is also available to meet personalized engineering requirements. Compared with conventional split‑site construction, modular installation effectively avoids air leakage caused by excessive on‑site joints and poor sealing, achieving remarkable improvement in overall air‑tightness.
From the operation and maintenance perspective, the modular ceiling air‑supply system features detachable split‑structure. Filter modules, flow‑uniformizing modules and plenum modules can be disassembled independently. Filter replacement, equipment cleaning and leak‑detection inspection do not require full disassembly of the whole unit; a single operator can complete maintenance rapidly, lifting O&M efficiency by more than 50 %. The compact overall structure leaves no hidden joint gaps. Its smooth surface allows easy cleaning and tolerates routine disinfection agents such as alcohol and sanitizers, preventing dust accumulation and dirt trapping, thus substantially cutting daily cleaning and maintenance expenses for cleanrooms.
In terms of cost advantages, prefabricated modular manufacturing lowers equipment production costs. Light‑weight on‑site installation reduces labor and auxiliary‑material expenditure. Furthermore, superior air‑tightness and stable operation bring down long‑term energy consumption. The total construction and O&M cost is approximately 30 % lower than that of traditional split‑type systems. At present, modular ceiling air‑supply systems have been widely deployed in small‑and‑medium‑size clean manufacturing plants and laboratories, serving as key equipment for cost‑effective clean‑room construction. Industry engineering experts point out that modular integration represents a major development trend for purification equipment. The modular upgrade of ceiling air‑supply systems effectively solves the pain points of difficult construction, high cost and complicated maintenance in conventional clean‑engineering projects, and drives the standardized and lightweight development of the clean‑engineering sector.
