Definition
| FFU is the full name of Fan Filter Unit, and the Chinese professional term is Fan Filter Unit. To be precise, it is a modular terminal air supply device with self-power and filtering function. FFU is equipped with primary and high-efficiency double-stage filters. The fan sucks air from the top of FFU and filters it through primary and high-efficiency filters. The filtered clean air is uniformly delivered at a wind speed of 0.45M/S±20% on the entire air outlet surface; It provides high-quality clean air for clean rooms and microenvironments of different levels; in the construction and renovation of clean rooms, the cleanliness level of the clean room can be quickly changed by adjusting the number of FFUs. |

Group control system
The FFU group control system can effectively solve the problems of large number and difficult maintenance during the use of the factory through modular connection;
Function:
1. Through dedicated protocols, the LCD touch screen is directly controlled, making use, operation and maintenance more concise and clear;
2. The working interface can correspond to the on-site layout one by one, and online real-time monitoring can be used to promptly remind filter replacement and troubleshooting;
3. Remote monitoring can be carried out via mobile phone or computer, which facilitates intelligent and unified management of the factory.
