Energy-Efficient FFU with HEPA Filtration for Modular & Class 100 Cleanrooms

Our Fan Filter Unit (FFU) is engineered to provide stable, uniform airflow for cleanroom environments with strict contamination control requirements. With stepless speed control, low vibration, and ultra-low noise operation, it delivers reliable performance while minimizing maintenance over long-term use.

Each FFU is individually tested prior to shipment in accordance with ISO 14644-1, using particle counters to verify filtration efficiency and airflow consistency. The system supports centralized control of multiple units, making it ideal for large-scale cleanroom installations while reducing failure rates and operating costs.

Designed for high energy efficiency and low heat output, this FFU helps maintain stable temperature and cleanliness conditions. It is well suited for ultra-clean production lines, Class 100 (ISO 5) assembly areas, and modular cleanroom systems.

Q1: What cleanroom classes are these FFUs suitable for?
A: These FFUs are suitable for ISO Class 5 to ISO Class 8 cleanrooms. When arranged in high-density layouts, they can form Class 100 (ISO 5) ultra-clean production lines.

Q2: Can multiple FFUs be controlled centrally?
A: Yes. The FFUs support centralized multi-unit control, allowing unified speed adjustment, monitoring, and system management, which helps reduce failure rates and operating costs.

Q3: Are the FFUs tested before delivery?
A: Yes. Each unit is individually tested prior to shipment in accordance with ISO 14644-1, using particle counters to verify airflow uniformity and filtration performance.

Q4: What type of filter is used, and can it be replaced?
A: The FFU is equipped with HEPA filters rated at 99.99% efficiency at 0.3 μm. Filters are replaceable and designed for easy maintenance during routine servicing.

Q5: How does the FFU help reduce cleanroom operating costs?
A: The high-efficiency motor, low heat output, and optimized airflow design reduce energy consumption, cooling load, and maintenance frequency, resulting in lower total operating costs.
