What is DC FFU?

Application of DC FFU:
DC FFU is suitable for manufacturers of semiconductors, electronics, flat panel displays, and disk drives, as well as optical, biotechnology, and other places with strict control requirements for air pollution. DC FFU quickly occupied the market with its unique advantages and reasonable price. DC FFU has flexible and versatile control methods, making the control of FFU more arbitrary.

FFU Introduction:
Fan Filter Units, abbreviated as FFUs. It is a self powered end air supply device with filtering function; The fan sucks in air from the top and filters it through high-efficiency particulate air (HEPA), and then evenly sends out clean air from the outlet surface after filtration; To provide clean air and particulate filtration control for clean environments, tailored to meet the needs of different enterprises and research institutions for different clean environments. Modular connection for use. Widely applicable to various clean rooms with cleanliness levels ranging from Class 1 to 1000, and can be assembled into ultra clean production lines, clean studios, clean rooms, dust-free wardrobes, and ultra clean workbenches. We can produce non-standard products according to customer requirements.

DC FFU fan filter unit, with adjustable FFU wind speed, actual current LED display, fault alarm, overload protection functions, and can be set with local control (i.e. single unit control) and remote centralized control function (RS485).

Overview of DC FFU:
DC FFU has a long working time, low noise, maintenance free, low vibration, stepless speed regulation, uniform wind speed, and easy installation.
DC FFU can be modularly connected and used, making it widely used in cleanrooms, cleanroom workstations, cleanroom production lines, modular cleanrooms, and local Class 100 applications. FFU is equipped with primary and high-efficiency two-stage filters. The fan sucks in air from the top of the FFU and filters it through primary and high-efficiency filters. The filtered clean air is sent out at a constant speed of 0.45M/s ± 20% on the entire air outlet surface. It provides high-quality clean air for cleanrooms and microenvironments of different sizes and cleanliness levels. In the renovation and renovation of newly built cleanrooms and cleanrooms, the cleanliness level can be improved, noise and vibration can be reduced, and the cost can be greatly reduced. Installation and maintenance are convenient, making it an ideal component for clean environments.

Characteristics of DC FFU:
1. FFU dimensions (mm): 1175 * 575 * 320, noise level of 52-56 decibels;
2. The FFU casing and high-efficiency filter adopt a split design, making installation and replacement more convenient and efficient;
3. The fan adopts German DC centrifugal fan or domestic aluminum impeller centrifugal fan, with a working time of more than 50000 hours;
4. It has the characteristics of energy saving, centralized computer control, stable operation, low noise, and digital adjustment;
FFU adopts a unique air duct with uniform wind speed, and the entire air outlet surface is uniformly sent out at a wind speed of 0.45M/s.
6. The shell can be made of mirror stainless steel, aluminum zinc coated plate, or cold plate electrostatic spraying to create a beautiful and elegant appearance;
Before leaving the factory, FFUs are scanned and tested one by one using a laser particle counter according to the US Federal Standard (209E) to ensure quality;
FFU is suitable for cleanrooms ranging from 10 to 10000 levels, facilitating centralized control of overall operation;

DC FFU transportation and installation:
1. Please handle the products in a well packaged state with the fan filter unit, and be sure to keep them level during transportation. If using lightweight carts or other tools for transportation, please choose a cart with a platform that exceeds the width of the body packaging.
2. After installation, at least 30 centimeters of space must be reserved above the body for future maintenance. Without sufficient maintenance space reserved, the body will not be able to be repaired or parts replaced.
3. Before trial operation, please remove the protective film attached to the suction port and under the flow plate.

Development of DC FFU:
With the continuous development of the economy and the improvement of people's living standards, people's requirements for product quality are also increasing. This puts forward higher requirements for production technology and production environment, so the level of clean environment directly determines the quality and efficiency of products. Especially in the fields of electronics, pharmaceuticals, food, biotechnology, healthcare, laboratories, etc., there are strict requirements for the cleanliness of production environments.

Therefore, different customers have different design and usage requirements for clean engineering, and their clean environment levels are also individually different. There will be different levels of design requirements for air purification system engineering, such as level 10, level 100, level 10000, etc. To meet the actual needs of enterprises, Zijing combines the design and practical use of many advanced clean rooms in China, starting from factors such as initial investment of investors, to the actual clean environment required by the enterprise.

DC FFU is controlled reasonably based on various technical indicators of the production environment to meet the requirements of special production processes. Especially in recent years, the promotion of environmental protection and energy conservation policies in China has deeply penetrated people's hearts. Many large, medium, and small cities have requirements and restrictions for investors, mainly focusing on energy conservation, environmental protection, and sustainable development. And these are all research and development directions of Zijing in the field of clean engineering.

At present, the fan filtration unit (DC FFU) is the quietest and most cost-effective air filtration unit on the market. All its constituent materials are tested as low chemical gas dispersing materials for certain special industries, and the air flow is very good.

The DC FFU produced by Zijing has absorbed the advantages of domestic and foreign manufacturers of fan filter units, optimized product design, and made the fan filter unit have the characteristics of compact structure, high air volume, low noise, low energy consumption, more energy saving and environmental protection.

At the same time, the lifespan of the fan filtration unit is longer, and the control and matching are more flexible. Beneficial for FFU (alternating current (AC)/direct current (EC)) to meet the needs of different environments.

In addition, the outer frame material is high-strength surface coated aluminum zinc plate (process material optional), and SUS304 stainless steel, aluminum oxide plate, cold rolled steel plate spray coating and other materials can also be selected. Widely used in various cleanrooms with cleanliness levels ranging from Class 1 to 1000, and can be assembled into ultra clean production lines, cleanrooms, cleanrooms, dust-free wardrobes, and ultra clean workbenches. We can also produce non-standard products according to customer requirements.

Zijing's products strictly follow China's testing standards to ensure their quality.

Regular maintenance of DC FFU:
(1) Regular maintenance project
Please conduct regular inspections on the fan filter unit as shown in Table 3. When the lifespan of the components has expired, please replace them immediately. (Component lifespan refers to the lifespan under general usage conditions, which may vary depending on the usage environment and conditions.).
(2) When an accident occurs due to force majeure (such as earthquakes, electric shocks, etc.) or chemical leakage (corrosive gases, etc.) and the machine is stopped and restarted, it is necessary to carry out the same inspection.
