Company profile
YeSiang Enterprise Co. Ltd was founded in 1987 and specializes in AMC, or Airborne Molecular Contamination, filtration technologies for demanding semiconductor cleanroom environments. The company provides fully integrated and customized filtration services and states that its market share is above 80% in sub-5nm advanced nodes and above 50% overall. YeSiang Enterprise Co. Ltd states that it is the only company in Taiwan with three ITRI-grade AMC testing laboratories. Its technical network includes strategic partnerships with global fabs and cleanroom contractors, while its filter solutions are used across wafer, memory, packaging, display, and data-center industries. Its full-lifecycle service spans design, production, logistics, installation, and recycling, linking filter engineering with supply and end-of-life handling. The company states that it is the world's first manufacturer certified with both BS 8001:2017 Circular Economy and ISO 14067:2018 Carbon Footprint. In 2024, YeSiang Enterprise Co. Ltd states that it launched the world's first carbon-neutral chemical filter and established two regeneration centers in Tainan. Those regeneration centers support filter recycling and activated-carbon regeneration for cylinder filters as part of the company's circular-economy model. For digital manufacturing, the company integrates SAP, CRM, and MES in a smart-manufacturing system designed for full traceability and flexible production control. Its operating model also includes an in-house logistics fleet, warehouse management, and localized production to respond to changing customer requirements. Listed certifications include BS 8001:2017, ISO 14067, ISO 14064, ISO 9001, ISO 14001, and ISO 45001, covering circular economy, carbon, quality, environment, and occupational safety management areas. Listed 2024 recognitions include the Global Views ESG Sustainability Award for Outstanding Low-Carbon Solution, the MOEA Rising Star Enterprise Award, and the Golden Jade Elite Award 100 MVP. The company's service locations span Mainland China, the United States, Japan, Europe, Singapore, Malaysia, and Taiwan, providing a multi-region support footprint for its chemical-filtration business.
Exhibits
The Make-up Air Unit, or MAU, is described as core equipment for the initial treatment of outdoor air in a cleanroom circulation system, directly affecting indoor air quality, facility conditions, production efficiency, and product quality. The listed MAU functions are particulate-matter filtration, AMC filtration, maintenance of positive indoor pressure differential, and control of temperature and relative humidity. When outdoor-air absolute humidity is above the cleanroom target, the MAU first uses a pre-cooling coil to lower the dew point and then a pre-heating coil to bring the airflow to a suitable temperature before it mixes with equipment sensible-heat airflow. At the outlet, a high-efficiency filter provides particle-filtration efficiency above 99.7% and removes multiple types of AMC to support the required cleanroom cleanliness level. Because the MAU processes large volumes of outdoor air, the company describes its energy use as the largest share of the cleanroom circulation system and therefore treats energy efficiency as a major design consideration. For MAU applications, YeSiang Enterprise Co. Ltd provides traditional V-type single-header and box-type chemical-filter options that can be matched to different MAU design specifications. Its self-developed patented cylinder filtration system is described as combining higher filtration efficiency with lower pressure drop, reducing operating energy use while strengthening contaminant removal. The chemical cylinder is certified to ISO 14067:2018 and BS 8001:2017, and the MAU solution page states that, compared with disposable filter media, it can reduce carbon emissions by about 25%. The 4V/6V V-Type Filter (Single Header) is locally produced and customizable for high-airflow environments, uses enlarged filter area to combine filtration efficiency with energy-use efficiency, supports quick fixing to existing site frames, and is designed for compatibility and expansion with multiple existing systems. For the 4V/6V single-header filter, listed installation positions include MAU, FFU, RCU, Dry coil, and Tools; removable gases include VOCs, Base, Acid, H2S, DMS, CS2, NH3, and O3; and frame materials include stainless steel, galvanized steel, aluminum, and ABS. The Cylinder Filter is locally produced, customizable, and supports filter-media regeneration; it is intended for large-air-volume intake conditions and is described as high-efficiency, low-pressure-drop, and long-life. The cylinder design is described as 99% reusable with high regeneration capability, uses a quick-disassembly design for easier maintenance, and states that its ISO 14067 certified configuration can reduce carbon emissions by more than 36% compared with disposable products. Cylinder-filter installation positions include MAU, FFU, RCU, Dry coil, and Tools; listed removable gases are VOCS, Base, Acid, H2S, DMS, CS2, NH3, and O3; and listed frame materials are stainless steel, aluminum, ABS, and PP. The 6V-Type Filter (Box) is locally produced and customizable for high-airflow environments, combines enlarged filter area with efficiency and energy-use considerations, supports fast fixing to existing frames, and lists the same MAU, FFU, RCU, Dry coil, and Tools installation positions. The Panel Type Filter is locally produced and customizable, offers flexible size design and multiple specifications for production supply, is described as high-efficiency and long-life, and is broadly applied to FFU and equipment tools. For the panel filter, listed removable gases include TS, DMS, Acid, Base, TVOC, CXF, IPA, and Acetone, and frame-material options include stainless steel, galvanized steel, aluminum, and ABS. The wider solution portfolio includes Make-up Air Unit solutions, Fan Filter Unit solutions, equipment-process or Tools solutions, Data Center solutions, and Petrochemical Ventilation Filtration solutions.
