Which clean equipment and local purification scenarios is DC FFU suitable for?
Differences between DC FFU and AC FFU
DC FFU uses brushless DC motors (also called EC motors), and AC FFU uses AC motors. There are differences between the two in terms of speed regulation methods, energy efficiency, starting characteristics and control supporting equipment.
DC FFU has a wide speed regulation range, high efficiency when running at low speed, and the starting current is close to the rated value. DC FFU usually supports 0-10V, PWM or RS485 communication speed adjustment, making it easy to access the group control system. AC FFU has a simple structure and lower cost, but its speed regulation range and control accuracy are not as good as DC FFU.
Therefore, DC FFU is more suitable for scenarios that require fine speed regulation, group control access, low noise or long-term continuous operation. Aili Industrial has complete self-research capabilities in FFU motors and control systems, and can provide DC FFU configuration solutions. For the basic structure of the FFU machine, you can refer toAili Industrial FFU fan filter unit。
Device-side supporting scenarios
Device-side supporting is one of the main application scenarios of DC FFU. Semiconductor cleaning machines, glue coating and development equipment, etching equipment, EFEM and other equipment have compact internal spaces and have clear requirements for the speed regulation and volume of the air supply unit.
The equipment-side DC FFU usually needs to be linked with the equipment control system to adjust the speed according to the process status. For example, keep the wind speed high during wafer transfer and reduce the speed during standby. The speed regulation accuracy and communication interface of DC FFU are more suitable for this linkage requirement.
For device-side applications, you can refer toEquipment end fan filter unit andCustomize the EFU equipment-end fan filter unit to learn about supporting solutions.
SMT and electronic workstation scenarios
The requirements for clean air supply in SMT workshops and electronic assembly stations include: stable wind speed, low noise, and local protection. DC FFU can finely adjust the speed according to the needs of the workstation to avoid local wind speed being too high or too low.
If the workstation needs to reduce the air supply during non-production periods, DC FFU can be adjusted by partition through the group control system. If the workstation is sensitive to noise, DC FFU has lower noise when running at low speed and is suitable for workstations close to human operations.
For placement machine matching, you can refer toSpecial FFU/EFU for SMT placement machines to understand the selection ideas.
Large clean room group control scene
In a large clean room, the number of FFUs may reach thousands. DC FFU supports RS485 communication speed regulation, which facilitates access to the group control system and realizes partition control, status monitoring and operation plan management.
The energy efficiency advantage of DC FFU is more obvious in long-term continuous operation. If the project is sensitive to operating costs, the energy consumption savings of DC FFU can be reflected in the operating cycle.
Regarding the group control system, you can refer toFFU/EFU group control touch screen controller andFFU computer group control system。
Scenarios with low noise requirements
Some clean rooms or equipment have clear requirements for noise. For example, near optical detection equipment, work stations where personnel operate for a long time, clean areas of hospitals, etc. DC FFU has lower noise when running at low speed and is suitable for these scenarios.
If the project also requires vibration, the smooth running characteristics of DC FFU may be more suitable. For vibration control, please refer toHow does the FFU above the optical inspection equipment take into account particle control and vibration requirements? Understand the vibration reduction scheme.
Energy saving and operating cost sensitive scenarios
DC FFU has higher efficiency under partial load. If the project needs to run for a long time, or the air supply volume is reduced during non-production periods, the energy consumption savings of DC FFU may be more obvious.
If the project needs to calculate operating costs, you can refer toHow to calculate FFU annual power consumption? Learn about the sub-model accounting method.
Features of Aili Industrial DC FFU
Aili Industrial independently designs and produces FFU-specific EC motors and controllers. The motor magnetic circuit is optimized for the load characteristics of the FFU centrifugal fan, and is more efficient in commonly used working areas. The driver control algorithm matches the motor parameters and the operating noise is low.
Aili Industrial's EC DC FFU supports RS485/Modbus protocol to connect to the central control system, which can cover the centralized monitoring and partition management of thousand-level FFU. The EC motor has been verified by dynamic balancing testing and continuous aging operation, and is suitable for long-term continuous operation.
Issues that should be confirmed in advance during project communication
During the DC FFU selection stage, it is recommended to confirm the following with the manufacturer: application scenarios and space conditions; speed regulation methods and ranges; communication interfaces and protocols; group control system compatibility; target air volume and static pressure; noise and vibration requirements; operating modes and energy consumption requirements; whether equipment-side customization is required.
