Do you know the installation steps and use of the fan filter unit?
Fan filter unit is a ceiling unit equipped with internal fans, which is used in turbulent and laminar flow clean rooms. The unit is flexible in design. According to the design specifications, it can easily cooperate with any ceiling framework to meet the requirements of class 1000 to class 1.
Fan filter unit is one of the quietest and most expensive units in the clean market. With this unit, high quality air can be delivered to the clean room. Moreover, the air manifold is good. It is suitable for semiconductor, electronic, flat panel display and disk drive manufacturers, optical, biological industries and other industries to be used in clean room, clean bench, clean production line, assembly type clean room, local Grade 100 and other places with strict control requirements for air pollution, with low energy consumption and low operation cost.
1、 Installation steps of fan filter unit (FFU)
1. Shut down the machine when installing the filter;
2. Before installation, point the new high-efficiency filter at the bright place, and visually observe whether the high-efficiency filter is damaged due to transportation and other reasons. If there is a hole in the filter paper, it cannot be used;
3. The fan filter unit is mainly used in the renovation of new clean rooms and clean workshops to improve the cleanliness level and reduce noise;
4. When installing the high-efficiency filter, first lift the box, then take out the failed high-efficiency filter and replace it with a new high-efficiency filter to ensure that the box cover is back in place after the frame is sealed;
5. When installing the high efficiency filter, special attention shall be paid to unpacking, handling and installation to ensure that the filter paper is intact. It is forbidden to touch the filter paper by hand to cause damage.
2、 Fan filter unit (FFU) purpose
1. The fan filter unit is mainly used in the renovation of new clean room and clean workshop, which can improve the cleanliness level, reduce noise and vibration, greatly reduce the cost, facilitate installation and maintenance, and is an ideal part of clean environment;
2. The fan filter unit can be connected and used in a modular way, which makes CSCEC Southern FFU fan filter unit widely used in dust-free room, dust-free operation platform, dust-free production line, assembled dust-free room, local class 100 and other applications. FFU fan filter unit can be equipped with primary and high efficiency two-stage filter screen;
3. The fan filter unit is particularly suitable for assembling into super clean production line. It can be arranged as a single FFU according to the process needs, or multiple FFUs can form a class 100 assembly line;
4. Computer group control system function of fan filter unit;
5. The fan filter unit reduces the operation cost, FFU is simple and convenient in the later operation and maintenance; it can be controlled and managed in different areas, saving energy, and really meets the low-carbon requirements advocated at present.
When the differential pressure gauge shows that the resistance of the air filter reaches 2-3 times of the initial resistance, the maintenance or replacement of the air filter shall be stopped. The installation of fan filter unit is to install high efficiency air filter through the prompt in PLC control system or the prompt of differential pressure meter.
The above is to share with you the relevant content of the fan filter unit. I hope that through the above content, we can have a further understanding of the fan filter unit products.
