  • Why do semiconductor cleanrooms predominantly use the FFU model?
    Jan 29, 2026
    Why do semiconductor cleanrooms predominantly use the FFU model?
     Semiconductor Cleanrooms (primarily FFU model)    I. Cleanliness Requirements and Airflow Control Methods   High Local Cleanliness Requirements: Processes such as photolithography and etching in semiconductor manufacturing require maintaining Class 100 (ISO 5) or even higher cleanliness levels around the equipment. FFU(Fan Filter Unit)can create a stable unidirectional airflow (0.25~0.35 m/s) in critical areas through modular layout, directly covering the equipment operating surface.   Flexibility: FFU(Fan Filter Unit) allow for quick adjustment of local clean areas, adapting to equipment updates or production line changes without modifying the entire air supply system.   Thermal Load Management: Semiconductor equipment generates significant heat. The decentralized air supply of FFU(Fan Filter Unit)optimizes local heat dissipation, avoiding airflow disturbances caused by temperature increases in centralized air supply systems.      II. Energy Consumption and Cost Differences    Energy-Saving Advantages: FFU(Fan Filter Unit)use DC/EC motors with efficiency reaching 75%~80%, and support on-demand speed adjustment, resulting in lower energy consumption per unit of airflow compared to centralized systems.   Low Maintenance Costs: The modular design simplifies filter replacement and troubleshooting, reducing downtime.      III. Industry Characteristics and Technological Adaptation    Process Dynamics: Frequent production line upgrades and equipment iterations require cleanrooms to adapt quickly. The modular characteristics of FFU (such as adding or removing units and adjusting the layout) are superior to fixed systems.   Micro-Contamination Control: Semiconductors are sensitive to 0.1 μm particles. The ULPA filters in FFU (filtration efficiency ≥99.999%) can specifically protect critical areas.  
  • High Air Filter Resistance = High Energy Consumption? How to Reduce Ventilation System Operating Costs
    Jan 22, 2026
    High Air Filter Resistance = High Energy Consumption? How to Reduce Ventilation System Operating Costs
    In the operation of air filtration systems, the relationship between air filter resistance and energy consumption is a core concern for many companies in controlling operating and maintenance costs. Every 100 Pa increase in air filter resistance significantly increases the energy consumption of the ventilation system's fan.    Why does high air filter resistance lead to high energy consumption?  The core of a ventilation system is the fan, whose function is to overcome the resistance of the entire system and move air in and out.   As the usage time increases, more dust and impurities accumulate on the air filter, causing the resistance to continuously increase. The fan then needs to output more power to overcome this resistance, leading to a surge in power consumption.   Data shows that when the air filter resistance increases to twice its initial value, the fan's energy consumption may increase by more than 30%! Air filter resistance is not a constant value; it gradually increases with the increase in the dust-holding capacity of the air filter material. When the resistance exceeds the design threshold, it not only increases energy consumption but may also affect the ventilation volume, thereby disrupting the stability of the clean environment. Mastering scientific resistance reduction methods can effectively balance filtration efficiency and operating costs, achieving efficient and energy-saving system operation.    Choosing the right filter type: Controlling initial resistance from the source  Initial resistance is one of the core performance parameters of a air filter and a key factor in determining the system's basic energy consumption. During the selection phase, it is necessary to choose low-resistance and suitable air filter products based on the actual application scenario.   1. Prioritize products with large filtration areas: Under the same filtration efficiency, the larger the filtration area, the slower the airflow through the filter material, and the lower the initial resistance. For example, the initial resistance of a Pleated Pre-filter is far lower than that of a pleated Pre-filter of the same specifications; medium-efficiency pocket filters further reduce resistance by increasing the number and volume of filter bags.     2. Match the filtration efficiency level: Avoid "over-specifying," and choose air filters with the corresponding efficiency based on downstream purification requirements. If only large particles of dust need to be intercepted, blindly choosing a high-grade air filter will significantly increase the initial resistance, causing unnecessary energy waste.   3. Choose high-quality, low-resistance air filter materials: High-quality air filter materials have a more reasonable fiber arrangement and better air permeability. Optimizing Installation and Configuration Methods   A reasonable installation layout and filter layer combination can reduce airflow resistance losses within the system, preventing increased energy consumption caused by excessively high local resistance.   1. Ensure installation airtightness: Gaps between the filter and the frame can lead to airflow short-circuiting, affecting not only the filtration effect but also causing local airflow turbulence, indirectly increasing system resistance. During installation, strictly follow specifications and use sealing strips or edge sealing designs to ensure a seamless connection.   2. Scientifically design the filtration stages: Follow the progressive filtration principle of "pre-filter - medium-efficiency filter - high-efficiency filter," allowing different levels of filters to perform their respective functions. The pre-filter intercepts large particles, and the medium-efficiency filter captures fine dust, preventing large particles from directly entering the high-efficiency filter. This extends the service life of the high-efficiency filter and maintains the stability of the overall system resistance.   3. Reasonably arrange the number of filters: Based on the airflow requirements of the ventilation system, reasonably configure the number and arrangement of filters to avoid rapid resistance increase due to airflow overload on a single filter unit.     The positive correlation between air filter resistance and energy consumption means that reducing resistance is the core path to cost reduction. Scientific control at every stage, from selection and installation to operation and maintenance, can achieve energy-efficient and high-performance operation of the ventilation system.
  • The Role of Fan Filter Units in Cleanrooms
    Jan 09, 2026
    The Role of Fan Filter Units in Cleanrooms
    Cleanroom facilities have different cleanliness level requirements depending on their intended use, such as Class 100, Class 1000, Class 10000, Class 100,000, Class 300,000, or even higher cleanliness levels.  The FFU (Fan Filter Unit) was developed to address these varying requirements. The emergence of FFU(Fan Filter Unit) has effectively solved this problem.   Using FFU(Fan Filter Unit) can effectively solve problems in cleanroom engineering.      The main advantages are:  1. Space Saving – Using FFU(Fan Filter Unit) saves space and solves the problem of limited maintenance space above the cleanroom ceiling. High-level cleanrooms require Class 100 or even Class 10 laminar flow hoods to meet process requirements.  This necessitates large supply air plenums above the cleanroom ceiling, containing ventilation fans. These plenums, along with supply and return air ducts, occupy a significant amount of space, resulting in limited maintenance access and sometimes even obstructing fire escape routes. When using FFU(Fan Filter Unit), the cleanroom ceiling is divided into several modules, each module being an FFU(Fan Filter Unit). This allows for adjustment of each module to meet the pressure balance requirements of the supply air plenum above the ceiling, significantly reducing the required height of the plenum. It also eliminates the need for large supply and return air ducts, thus saving installation space. This is particularly beneficial in renovation projects where ceiling height is limited. FFU(Fan Filter Unit) come in various sizes and can be customized to the actual size of the cleanroom. Because they occupy less height within the supply air plenum and essentially no space within the cleanroom itself, they offer significant space savings.   2. FFU Flexibility – The independent structure of FFU(Fan Filter Unit) allows for easy adjustment, compensating for the lack of flexibility in cleanroom design and addressing the limitations of fixed production processes. Cleanroom facilities are generally constructed with metal panels, and once built, the layout cannot be easily changed. However, due to continuous updates in production processes, the original cleanroom layout may no longer meet the needs of new processes, leading to frequent modifications and significant waste of resources and money due to product changes. By increasing or decreasing the number of FFUs, the cleanliness layout of the room can be adjusted locally to meet changes in the process.  Since FFUs have their own power, air outlets, and lighting, significant investment can be saved. This is almost impossible to achieve with typical centralized air supply purification systems. Because FFUs are self-powered, they are not limited by area. In a large cleanroom, they can be controlled in zones as needed. Furthermore, as semiconductor manufacturing processes change, the factory layout will inevitably require corresponding adjustments. The flexibility of FFUs makes these adjustments easy and avoids secondary investment.     3. Reduced operating burden – The FFU (Fan Filter Unit) system is energy-efficient, thus overcoming the disadvantages of centralized air supply systems, such as large air conditioning rooms and high operating costs of air conditioning units. If individual cleanrooms in a large cleanroom facility require a higher level of cleanliness, a centralized air conditioning unit would require a larger airflow and higher fan pressure to overcome the resistance of the ductwork, pre-filters, medium-efficiency filters, and high-efficiency filters to meet the requirements. Moreover, in a centralized air supply system, if an air conditioning unit malfunctions, all cleanrooms served by that unit will cease operation.
