Product Descriptions
FFU Clean Unit for Modular Clean Air Supply
An FFU, or Fan Filter Unit, is a modular terminal air supply device used to create stable clean airflow in controlled environments. It combines a built-in fan with HEPA or ULPA filtration to provide localized high-cleanliness air supply for cleanrooms, clean booths, clean tents, production lines, and equipment protection areas.
FFUs are widely used in electronics, semiconductors, biopharmaceuticals, medical devices, laboratories, precision manufacturing, and other industries requiring flexible, efficient, and reliable clean air solutions.
1. Core Functions
| Function | Working Principle | Customer Value |
|---|---|---|
| Localized High Cleanliness | The built-in fan draws air from the top and supplies it through HEPA or ULPA filters as uniform clean airflow. | Creates local Class 10, Class 100, or Class 1000 clean environments for critical processes. |
| Flexible Layout | Modular units can be installed on ceiling grids or clean booth frames without complex centralized ductwork. | Supports easy installation, layout adjustment, cleanliness upgrades, and future expansion. |
| Energy Saving Operation | FFUs reduce duct resistance and can be controlled by zone, time, or process demand. | Helps reduce operating costs during non-production hours or in low-load areas. |
| Negative Pressure Sealing | The fan is positioned upstream of the filter, keeping the filter section under negative pressure. | Helps prevent unfiltered leakage from contaminating the clean air supply. |

3. Modular Installation and Maintenance
FFUs are designed for modular installation. Each unit can be installed, removed, or maintained independently, making the system suitable for cleanrooms, clean booths, ceiling grids, equipment isolation areas, and production line upgrades.
When the workshop layout changes or a higher cleanliness level is required, the number and arrangement of FFUs can be adjusted without major reconstruction. This makes FFU systems practical for cleanroom renovation, expansion, and phased capacity upgrades.
4. Energy-Saving Control
Compared with traditional centralized air supply systems, FFU systems can reduce duct resistance and improve terminal air supply efficiency. Air volume can be adjusted according to production demand, cleanliness requirements, and operating schedules.
During non-production periods or in unoccupied areas, selected FFUs can be slowed down or turned off to reduce energy consumption while maintaining necessary environmental control.
5. Typical Applications
FFU clean units are suitable for semiconductor cleanrooms, electronics manufacturing, pharmaceutical cleanrooms, medical device workshops, laboratories, precision assembly areas, clean booths, clean tents, inspection zones, and equipment protection areas.
6. Customization Options
FFU units can be customized according to project requirements, including device size, air volume, filter grade, material selection, insulation, control method, noise level, installation layout, and cleanroom cleanliness target.
If you have special requirements for the product, please let us know your application scenario, cleanliness level, installation space, and airflow requirements.
