DC FFU Advantages |
|
Motor Type and Control Method |
When using an AC motor, airflow is typically regulated by voltage. |
Equipped with a DC brushless motor, it is electronically controlled via a controller or central monitoring system. |
It enables more precise airflow control and more intelligent system integration. |
|
Energy Efficiency |
Energy efficiency is stable, but relatively low. Power consumption increases significantly when operating at high airflow rates. |
Under the same airflow conditions, DC motors can reduce energy consumption by 30-50% compared to AC motors. |
Suitable for locations requiring long-term continuous operation and energy saving, with low energy consumption. |
|
Airflow Stability and Control |
It provides reliable and constant airflow, but has limited speed adjustment options. |
It supports stepless speed regulation, enabling precise airflow balance adjustment for large cleanroom fan coil unit arrays. |
Suitable for ISO 5-6 cleanrooms or facilities requiring precise airflow uniformity. |
|
Noise Level |
The operating noise level is relatively high. |
The operating noise is significantly lower. |
Improved operator comfort |
|
System Integration and Intelligent Control |
Typically, it runs independently or uses a simple local controller. |
It can be easily integrated into the management system. |
It enables centralized control, real-time feedback, and fault alarms. |

DC FFU Model
Applications And Case
Case Study: Electronics & Precision Manufacturing Zone
Background
The precision electronic component production workshop requires extremely high cleanliness, meeting ISO Class 6 standards. The production line operates 24/7. After prolonged use, the original AC FFU system exhibited high power consumption, significantly reduced airflow due to increased filter resistance, and large fluctuations in the number of 0.3-micron particles in critical areas, negatively impacting product quality.
Solution
This project implemented discount DC FFU air purifier from SYNRUI to create a modular air supply system. Each unit has an airflow rate between 800 and 1200 cubic meters per hour, and centralized control allows wind speed adjustment in different areas. The DC motor automatically adjusts airflow based on filter resistance, ensuring stable laminar flow in critical zones.
Results
Post-modification measurements showed that the power consumption of a single FFU decreased from 170 W to approximately 105 W, resulting in an overall system energy reduction of approximately 40%. After eight months of continuous operation, airflow deviation was controlled within ±10%, the average concentration of 0.3 μm particles decreased by 25%, and the product defect rate decreased by approximately 3%.
Reliability Explanation
The DC FFU air purifier factory uses a low-temperature-rise brushless DC motor capable of continuous operation for over 60,000 hours. Having undergone factory testing for airflow, noise, and electrical safety, it can reliably meet the cleanroom production requirements of electronics and precision manufacturing areas over the long term.
