Fan Filter Unit

Fan filter unit

FFU can be used by connecting module. It is widely used at the occasion such as clean room,
clean production line.
The FFU have prefilter and HEPA filter two layers filter net. The air is taken in from the top
of FFU by fan and then is filtered by prefilter and HEPA filter. The clean wind will be send
and the wind speed is 0.45+/-0.2m/s.
Characteristic: 1.The FFU matches centrifugal fan that is durable, low vibration and noise,
adjustable air velocity, stable capability and air velocity. The fan's life p-span is more than
50 thousand hours.
2. It is suitable to assemble the production line. It can dispose to be used as single set
according to crafts need and also can connect several sets to be 100 rank production lines.
3. The material is stainless steel, aluminum or cold rolled steel which is beautiful and prevent
to rust.
3. In order to ensure the quality of product, FFU will be inspected by particle counter before
out of factory according America Federal Standard 209E.

FFU fan filter units can be modularly connected for use, FFU is widely used in clean rooms, clean workstations, clean production lines, assembled clean rooms and partial class 100 applications, etc. Using FFU fan filter units can make simple clean workstations, clean sheds, clean transfer cabinets and clean storage cabinets, etc. It is suitable for obtaining a high level of clean environment in various environments. It provides high quality clean air for clean rooms and micro-environments of different sizes and cleanliness levels. In the new clean room and clean plant type renovation, it can improve the cleanliness level, reduce noise and vibration, also can greatly reduce the cost, easy to install and maintain, is the ideal part of clean environment.

A fan filter unit is a combination of a fan and a filter (HEPA or ULPA) to form a self-powered end purification unit. To be precise, it is a self-powered, modular end-supply unit with filtration efficiency.



FFU basic structure
(1), The box: its material commonly used galvanised aluminium alloy coated steel, aluminium alloy, stainless steel three. The function is to support the fan and the air guide ring, and the second is to support the flow guide.
(2), Guide plate: airflow equalisation device, built into the interior of the box, the fan below the surrounding.
(3), the fan: there are single AC (AC/1Phase), DC (EC/1Phase), three AC (AC/3Phase) three.
(4), Control components: for AC FFU, its commonly used five-speed governor or infinitely variable governor; DC system control chip embedded in the motor internal, with the help of special control software, computer, control gateway and network lines to achieve remote control.
(5), Filters.
Pre-filter: filtration of large dust particles, non-woven, primary filter, filter frame.
High efficiency filter: HEPA/ULPA (High Efficiency/Ultra High Efficiency).
Chemical filter (Chemical Filter): in addition to ammonia, boron, organic gases, etc., generally installed in the air inlet, the same as the pre-filter installation method.



FFU features
1, FFU purification level: static class 100.
2, FFU air speed is: 0.3/0.35/0.4/0.45/0.5m/s, FFU noise â?¤ 46dB, FFU power supply is 220V, 50Hz.
3, FFU adopts high efficiency filter without partition, FFU filtration efficiency is: 99.99% to ensure purification level.
4, The whole FFU is made of high quality aluminized zinc plate.
5, FFU stepless speed control design, speed control performance is stable, FFU in the state of high efficiency filter final resistance can still ensure the same air volume.
6, FFU uses high efficiency centrifugal fan, with long life, low noise, maintenance-free and low vibration.
7, FFU is especially suitable for assembling into ultra-clean production line, which can be arranged as FFU single unit according to the process needs, or FFU multiple units to form a 100-level assembly line.
