Product Description

FFU Group Control System
Overview:
 The FFU intelligent distributed control system is mainly used in the clean room of large electronic/pharmaceutical
factories, which can easily realize on-site distributed control and centralized management. It can flexibly control the start,
stop and speed adjustment of FFU fans. The control system uses partition control technology to solve the problem of
limited Rs485 drive capacity and can control up to several thousand fans. This control system includes the following three
parts:
 FFU computer management system (monitoring system) (optional according to requirements);
 FFU control host system (zoned data transfer system, each zone with up to 60 control units);
 Field FFU control unit (FFU group control unit controller, FFU single control unit controller, DC motor FFU unit
controller).

1. The FFU control unit uses a single-chip microcomputer as the core processor to realize the control function. It is the terminal controller of the FFU. One FFU unit module controls one FFU

2. Or parallel control

3. Make two FFUs. The FFU control unit can realize the following control functions:

4. (1) Control the start, stop and speed regulation of each FFU through the host:

5. (2) It can realize remote centralized control and fault diagnosis:

6. (3) Each control unit module has a settable ID address:

7. (4) With overload and no-load alarm function: when overload and no-load, the FFU control unit will be prompted to alarm.

8. 1. Main technical indicators:

9. 1. Power supply: 220VAC

10. 2. Control the three-stage speed regulation of the three-tap fan (fan power: 80-250w)

11. 3. Can participate in group control through Rs485 communication

12. 4. The digital tube displays the operating current value and setting status

13. 5. With short circuit protection and forced insertion functions

 

The FFU laminar flow air supply unit module can be connected and used. FFU is widely used in applications such as clean rooms, clean workbenches, clean production lines, assembled clean rooms and laminar flow hoods.

● The fan draws air in from the top of the FFU and passes through the filter. The filtered clean air is sent out uniformly at a wind speed of 0.45m/s±20% on the entire air outlet surface.

● Using the latest American technology, it is suitable for obtaining a high-level clean environment in various environments. It provides high-quality clean air for clean rooms and micro-environments of different sizes and different cleanliness levels.

 

Installation steps of fan filter unit (FFU):

　　 (1) When installing a high-efficiency filter, stop the machine.

　　(2) Before installation, point the new high-efficiency filter to a bright place, and observe with the naked eye whether the high-efficiency filter is damaged due to transportation or other reasons. If the filter paper has leaks, it cannot be used.

　　(3) The fan filter unit is mainly used in newly-built clean rooms and clean workshops. It can improve the cleanliness level, reduce noise and vibration, and also greatly reduce the cost. It is convenient to install and maintain. It is an ideal component for a clean environment.

　　(4) When installing the high-efficiency filter, first lift the box body, then take out the failed high-efficiency filter, replace it with a new one, make sure that the frame is sealed, and then return the box cover to the original position.

　　 (5) When installing the high-efficiency filter, pay special attention to unpacking, handling and installation to ensure that the filter paper is intact and undamaged, and it is forbidden to touch the filter paper to cause damage.

　　 2. Fan Filter Unit (FFU) Purpose:

　　(1) The fan filter unit is mainly used in newly-built clean rooms and clean factory-style renovations. It can improve the cleanliness level, reduce noise and vibration, and also greatly reduce the cost. It is convenient to install and maintain. It is an ideal component for a clean environment.

(2) The fan filter unit (FFU) can be used in modular connection, making the FFU fan filter unit *** used in clean rooms, dust-free operation tables, dust-free production lines, assembled clean rooms and local hundreds of applications . The FFU fan filter unit can be equipped with primary and high-efficiency two-stage filters.

　　(3) The fan filter unit (FFU) is particularly suitable for assembling into an ultra-clean production line. It can be arranged as a single FFU according to the process needs, or multiple FFUs can be used to form a 100-level assembly line.

　　(4) Fan filter unit (FFU) computer group control system function.

　　(5) The fan filter unit (FFU) reduces the operating cost. The FFU is simple and convenient in the later operation and maintenance; it can be controlled and managed in different areas and save energy, which truly meets the current low-carbon requirements.
