3. FFU
a. Introduction:
FFU is an English abbreviation, full known as Fan Filter Units, Chinese meaning "fan filter units", is a kind of self-powered, with filtering effect of modular end air supply device. Its main function is that the air is inhaled by the fan from the top of the FFU and filtered by the HEPA. The filtered clean air is evenly sent out at the entire outlet surface at the speed of 0.45m/s soil 20%, so as to meet the clean requirements of the clean environment. It is mainly installed in the clean area, the ceiling keel of the working area and the equipment machine. It is widely used in semiconductor, optical electronics, precision instruments, biopharmaceutical, aerospace, automobile, hospital, food, spraying, printing and other fields.

c. FFU Features
(1)Negative pressure ventilation
Because of its ability to provide static pressure. the clean room is positive pressure relative to the outside world. Therefore, external particles are not subject to leakage into the clean area makes sealing easy and safe.
(2)Save space
Compared to other systems.FFU system occupies less floor height in the supply air plenum. And basically does not occupy the clean room space.
(3)Shorten construction period
Using FFU saves the production and installation of air ducts.Shorten the construction period.
(4)Reduce operating costs
Although when choosing FFU. The initial investment is higher than using duct ventilation. However, in the later operation, it prominently shows the characteristics of energy saving and maintenance-free.
(5)Convenient and fast control
Remote and precise control of single or group FFU, And it is not affected by other pipe network systems.
(6)It is flexible and easy to replace, install and move
FFU is self-powered and self-contained modular. The matching hepa filter is easy to replace, so it is not restricted by the region: In the clean workshop. it can be installed. replaced and moved according to the needs, and it can be controlled by separated zone.
d. FFU advantages:
The FFU fan filter unit can be used in modular connection, which makes the FFU fan filter unit widely used in clean room, clean table, clean production line, assembled clean room and laminar flow cover and other applications.FFU fan filter unit with initial, high-efficiency two-stage filter. The fan draws the air from the top of the fan filter unit and filters through the primary and high efficiency filters.FFU fan filter unit has the following advantages:
(1)FFU is especially suitable for assembling into super-clean production line. It can be arranged as a single unit according to the process needs, or multiple sets can be connected in series to form a 100-stage assembly line.
(2)FFU fan filter unit adopts external rotor centrifugal fan, which has the characteristics of long life, low noise, no maintenance, small vibration and stepless speed regulation. Suitable for obtaining a higher level of clean environment in various environments.
(3)FFU for different areas, different levels of clean room, micro-environment to provide high-quality clean air. In the new clean room, clean workshop or renovation, it can not only improve the cleanliness level, reduce noise and reduce vibration, but also greatly reduce the cost. Easy to install and maintain, is the ideal component of clean environment.
(4)Shell structure is made of high quality aluminum-zinc plate, light weight, corrosion resistance, rust prevention, beautiful and generous.
(5)Unique internal diffusion plate, with uniform wind pressure diffusion and stable wind speed on the outlet surface;
(6)FFU laminar flow hoods are in accordance with the US Federal Standard 209E, and METOME dust particle counters are scanned and tested one by one to ensure the quality.
