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.
