The DC FFU (Fan Filter Unit) is an energy-efficient, self-contained air filtration module designed for ISO Class 1-8 cleanrooms. It integrates a brushless DC motor, HEPA/ULPA filter, and smart control system to provide laminar airflow with minimal energy consumption.
The main benefit of EFUs is that they help to maintain a clean and safe environment by removing airborne contaminants.
This can help to prevent the spread of infectious diseases, reduce the risk of equipment failure, and improve product quality.
Nice appearance, human centered design.
Light, thin shape-- application in low ceiling are also available.
Flexible, diversified design--Except for standard items, custom made FFU is available, such changings as filter nets, the materials of shell and etc.
Convenient design---lock are designed in the body, which makes it convenient to install and repair.
Premium Current-averaging design of the inside--Ensures deviation of the blowing side lower than ±10%.

Q1: How often should the HEPA filter be replaced?
A: Typically 3–5 years, but monitor via:
Pressure drop (replace if ΔP ≥2× initial value)
Particle count trends
Q2: Can DC FFUs replace traditional AC FFUs?
A: Yes – Direct retrofit with 30–50% energy savings.
Q3: What’s the difference between H13 and U15 filters?
Filter | Efficiency | Use Case |
---|---|---|
H13 | 99.95%@0.3μm | ISO 5-7 cleanrooms |
U15 | 99.9995%@0.12μm | ISO 1-3 semiconductor |
