Overview

FFU stands for Fan Filter Units, which means "Fan Filter Units" in Chinese. More precisely, it is a modular end air supply device with built-in power and filtering function. The fan sucks in air from the top of the FFU and filters it through HEP. The filtered clean air is evenly sent out at a wind speed of 0.45m/s ± 20% on the entire outlet surface.

FFU Overview

FFU has long working hours, low noise, maintenance free, low vibration, stepless speed regulation, uniform wind speed, and easy installation. 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.

The FFU laminar flow hood fan filter unit can be modularly connected and used, and FFU is widely used in clean rooms, clean workbenches, clean production lines, assembled clean rooms, and local level 100 applications.

The FFU laminar flow hood is equipped with primary and high-efficiency two-stage filter screens. 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.

The FFU filtration unit adopts the latest technology from the United States and is suitable for obtaining other clean environments in various environments. 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.

FFU Filter Unit Description

FFU (Fan Filter Unit) is a combination of a fan and a filter, also known as a "built-in fan filter device". FFU is usually installed at the end of the clean room's air supply, and is usually placed on a suspended "dry" gasket sealing keel frame. The upper part of FFU is the fan module, and the lower part is the filter. According to the requirements of cleanliness, the filter can be a high-efficiency (HEPA) or ultra high efficiency (ULPA) filter of different grades, providing clean air for the cleanroom. The fan module not only needs to overcome the resistance of the high-efficiency filter at the bottom of the FFU, but also needs to overcome the resistance of all channel components of the entire circulating air to maintain the set operating wind speed. The FFU system has the characteristics of simple design and construction, flexible wind speed adjustment, and easy change of clean areas, making it one of the popular forms of industrial clean room systems,The overall design of this unit is flexible and easy to use in conjunction with specialized ceiling frames and other suitable frames. When the filter adopts a knife edge frame, this unit can also be used for liquid tank sealing ceiling skeleton. According to the design specifications, it can easily match any ceiling skeleton to meet the cleanliness level requirements. The outer frame can be made of aluminum or stainless steel, each with its own characteristics. By using this unit, high-quality air can be delivered to the clean room with good air circulation. It 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.

The high-efficiency filter commonly used in Class 10000 cleanrooms can achieve a filtration efficiency of 99.99% for particles with a diameter of 0.3um in the air. The air outlet speed is 0.4m/s, and no external force exceeding 20KG should be applied to the filter to avoid damaging its organizational structure.

FFU has characteristics

Flexibility.

Because FFU is self powered, it is not limited by region. In a large clean room, zoning control can be implemented as needed. Moreover, with the changes in semiconductor production processes, the layout of the factory must be adjusted accordingly. The flexibility of FFU makes such adjustments easy and does not bring about secondary investment.

Secondly, reusability.

In theory, FFU devices that are temporarily unused can be disassembled, sealed, and properly stored for future use.

Thirdly, negative pressure ventilation.

This is the unique feature of FFU. Due to its ability to provide static pressure, the supply air static pressure box is under negative pressure relative to the cleanroom. In this way, the particles inside the static pressure box will not leak into the clean area under pressure, making the sealing simple and safe.

Fourthly, shorten the construction period.

The use of FFU eliminates the need for the production and installation of air ducts, as they occupy a significant portion of the construction period in clean engineering. Any investor hopes that their investment can bring in returns as soon as possible, and choosing FFU has become a possibility.

Fifth: Reduce operating costs.

Although the initial investment when choosing FFU is higher than using duct ventilation, it exhibits outstanding features such as energy saving and maintenance free operation in the later stage.
