DC FFU (DC FFU, EC FFU) is a fan filter unit that uses a DC fan as the driving component.
The equipment is usually installed on the ceiling of a clean room or above a clean area to:
Fan + filter + cabinet + controller integrated in one modular device.
During operation, the air enters the interior of the FFU, is driven by the fan and filtered through the HEPA or ULPA filter, and then sent to the clean area with a relatively stable air flow.
Compared with the ordinary AC fan solution, an important feature of the DC fan solution is that it is easy to adjust the speed and air volume, so the corresponding operation control can be carried out according to the actual operation needs of the clean room.
Aili Industry configures DC FFU products and matches fans according to the air volume, static pressure, installation size, filter and control requirements of different projects.
FFU adopts a modular structure and can be installed in conjunction with a clean room ceiling system.
Suitable for large-area clean rooms and local clean areas.
According to the actual conditions of different clean rooms, it can be:

DC FFU realizes the filtration and circulation of air in clean rooms through the combination of fans and filters. |
In actual operation of a clean room, the same air supply state is not always required.
For example:
There may be different air treatment requirements in production status, standby status, local process area operation, different clean area operations, different production shifts, etc.
Aili Industrial's DC wind solution can adjust the operating status of the fan through the control system, providing a more flexible control method for FFU operation management.
For clean rooms that need to centrally manage multiple FFUs, the corresponding FFU group control system can also be configured.。
FFU usually needs to run for a long time, so the operating status of the fan will affect the long-term energy consumption of the equipment.
Aili's industrial DC fan solution can be combined with the control system to adjust the speed and adjust the FFU operating status on the premise of meeting the actual air volume requirements of the clean room.
It should be noted that actual energy consumption is related to:
It is related to factors such as fan model, air volume, static pressure, filter resistance, fan efficiency, running time, control method, clean room design and other factors.
