SYNRUI FFUs utilize energy-efficient ECM motors, a uniform airflow aerodynamic system, and self-produced HEPA/ULPA filters to provide stable, low-noise, and highly efficient clean air for cleanrooms, semiconductor, pharmaceutical, and optoelectronic industries. They are key equipment for improving air quality and reducing energy consumption.
Internally, they integrate a fan system, multi-stage filters, noise reduction structures, and airflow equalization devices, providing a controllable unidirectional airflow environment for ISO3–ISO7 cleanrooms by continuously outputting a stable airflow velocity of 0.45 m/s (±20%).
Specifically designed for long-term operation, low energy consumption, and stable airflow output, they are suitable for large-scale cleanroom layouts or as the core air source for localized high-cleanliness areas.
Our FFU series includes the following:
HEPA FFU (H13/H14)
ULPA FFU (U15/U16)
Energy-efficient ECM FFU
Ultra-thin FFU (suitable for ultra-low ceilings)
Mini FFU (suitable for Mini Environments)
Chemical filtration FFU (optional)
Product Advantages
Energy-Saving Drive System: Energy Consumption Reduced by 20–35%
Utilizing PWM-Controlled ECM Brushless DC Motor:
Brushless structure reduces friction loss
High energy conversion efficiency
Low temperature rise during long-term operation
Lifespan increased by 30–50%
Compared to traditional AC fans, FFUs significantly reduce overall energy consumption, a key reason for their purchase by many semiconductor customers.
Optimized Aerodynamic Structure: More Uniform Airflow and Lower Noise
We use CFD simulation analysis of the air duct to optimize corners, vortex zones, and resistance points, resulting in:
Outlet airflow uniformity improved to ±5%
Noise reduction of 3–8 dB
Stable airflow even under high static pressure environments
Especially suitable for optical and electronic factories with extremely high requirements for uniform airflow.
Multi-stage filtration structure: High efficiency, low resistance, and longer lifespan
Configurable according to industry needs: pre-filter G4/F7, medium-efficiency filter F8/F9, HEPA H13/H14, ULPA U15/U16. SYNRUI manufactures and tests its own filter cartridges, performing MPPS efficiency scans on each unit to ensure filtration performance and energy saving.

FAQ
Q: 1. What is the typical airflow velocity of an FFU? Why this value?
A: Typically 0.45 m/s (±20%). This is the international standard airflow velocity for maintaining unidirectional airflow in cleanrooms, effectively reducing particle settling.
Q: 2. Why is an ECM motor more energy-efficient than an AC motor?
A: ECM uses a brushless structure, resulting in low energy loss, high efficiency, and supports precise PWM speed control, achieving overall energy savings of 20–35%.
Q: 3. How often should the FFU filter be replaced?
A: Generally 1–3 years, depending on the dust concentration, pre-filter level, and operating time.
Q: 4. Which cleanroom classes are suitable for FFUs?
A: ISO3–ISO7, depending on whether HEPA or ULPA is used.
Q: 5. Can FFUs be installed in existing cleanrooms?
A: Yes, they support T-grid, keel-type, and modular cleanroom structures.
Q: 6. Is noise level customizable?
A: Silent FFUs are available, with noise reduction achieved through optimized airflow, vibration damping, and specialized fans.
