[0002] FFU is a filter unit, a self-powered air filter device, a modular terminal air supply device with filtering function. It needs to be used with an FFU control box.

[0003] The patent document with application number CN214674956U discloses a DC brushless motor FFU control box, including a device body, a fixed welding point and a power port. The top of the device body is fixedly connected with a fixed welding point, and the other side of the bottom of the fixed welding point is fixedly connected with the power port. The bottom of the power port is embedded with a hexagonal screw, and one side of the hexagonal screw is fixedly connected with an open button. A driving mechanism is composed of a power-off memory, a filter unit and a constant speed control chip. When the control box is started to work, the current is filtered and transformed to a certain voltage value through the filter unit. At this time, the constant speed control chip controls and changes the frequency of the DC brushless motor stator power supply, thereby realizing speed regulation. When the control box is turned off and the power is cut off, the power-off memory stores and records the operating status before the power is cut off. When the power is turned on again, the power-off memory can be awakened for information sharing, so that the control box has a memory function.
