Component parts of FFU control unit

FFU control can be broadly divided multi-gear switching, continuous adjustment, computer control, such as several, but the functions are single control, zoning control, alarm, TFT Lcd Modules running status display.

But what causes FFU in such a long time has not been widely applied? There are three issues dominate.

First: the noise problem. You can think about at the time of the production process level, together with the noise of thousands of wind turbines would be?

Second: the pressure balance. To a large static pressure box, each with a different corner of the fan is able to get a balanced pressure, which at the time also can not be guaranteed.

Third: maintenance issues. FFU itself cost is relatively high, if it can not guarantee the life of the motor, then replace will bring additional investments. These are caused when companies do not choose to use FFU of the main reasons.
With the development of technology, these problems become easily.

One, first reduce the fan noise itself, character oled plus the unique duct design, improved efficiency of the fan, but also greatly reduces the noise

Second, the development of computers, advanced computer control system to solve the high-volume FFU pressure imbalance in the

Third, raise the level of the production process, extending the life of the fan; German EBM-quality centrifugal fan with long life, maintenance, small vibration and other features, the working life of 50,000 hours or more.
