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.

2x4 HEPA Fan Filter Unit is one of our main product.It is self-powered, and is self-contained modular, matching filters are easy to replace, so it is not restricted by the area; in the clean plant, it can be partitioned and controlled according to needs, replaced and moved as required. The full name of ffu is: fan filter unit, is a self-powered air supply filtration device, with filtration effect of the modular end of the air supply device, is a terminal air filtration equipment module. Principle The air is drawn in using the fan (motor + impeller) inside the filter unit of the FFU fan. The absorbed air is filtered by the HEPA (High Efficiency Filter) or ULPA (Ultra High Efficiency Filter) filter below the FFU to filter out the large particles of dust in the air, and finally the fresh air is sent to the clean area at an even speed. Composition Cabinet: The material commonly used is galvanised aluminium alloy coated steel, aluminium alloy and stainless steel. The role of one is to support the fan and the air guide ring, the second is to support the flow guide. Deflector plate: A balancing device for air flow, built into the interior of the box, around the underside of the fan. Blower: Available in single AC (AC/1Phase), DC (EC/1Phase) and triple AC (AC/3Phase). Control components: For AC FFU, five-speed governors or infinitely variable governors are commonly used; for DC systems, the control chip is embedded inside the motor and is controlled remotely with the help of special control software, computers, control gateways and network lines. Features 1, Flexible and easy to replace, install and move FFU is self-powered, and is self-contained modular, matching filters are easy to replace, so it is not restricted by the area; in the clean plant, it can be partitioned and controlled according to needs, replaced and moved as required. 2, Negative pressure ventilation This is a unique feature of FFU. As it provides static pressure itself, the clean room is under positive pressure in relation to the outside world, so that particles from outside do not leak into the clean area, making sealing easy and safe. 3, Shorter construction period The use of FFUs eliminates the need for ductwork and installation, shortening the construction period. 4, Reduced running costs Although the initial investment is higher than using duct ventilation when choosing FFU, it is outstandingly energy-efficient and maintenance-free in later operation. 5, Space saving Compared to other systems, the FFU system occupies less floor height in the air supply static pressure box, and basically does not occupy the clean room space.
