What is FFU?

FFU (Fan Filter Units) combines a fan and filter as a self-contained filtration device, typically installed at the cleanroom air supply terminal on a dry gasket-sealed ceiling grid. The upper section is the fan module and the lower section is the filter, which can be HEPA or ULPA depending on cleanliness requirements.

Key Features

• Flexibility: Self-powered units enable zoned control and easy layout changes without secondary investment.
• Reusability: Units can be removed, sealed, and stored for future use.
• Negative Pressure Ventilation: Provides static pressure to prevent particle leakage into clean zones.
• Shorter Construction Cycle: Eliminates duct fabrication and installation.
• Lower Operating Cost: Energy-efficient and low-maintenance in long-term operation.
