A Fan Filter Unit (FFU) is a self-contained air filtration device used in cleanroom environments to provide high-efficiency particulate air (HEPA) or ultra-low penetration air (ULPA) filtration. It consists of a fan, a filter, and a diffuser panel, all housed within a single unit.
FFUs are flexible and economic solutions to remove particles from the recirculated air of turbulent or unidirectional ventilated cleanrooms.
Flair FFU provides air purification solutions to meet your Cleanroom needs and expectations. They can provide a high level of air purification for your workspaces.

3. How does FFU work?
FFU is a motorized fan cleanroom equipment with HEPA/ULPA filter, Which can be installed in the filter ceiling grid of a cleanroom, FFU often consists of a pre-filter, a HEPA/ ULPA filter and the motorized fan with frame, which pulls air through the filters for distribution to cleanrooms or enclosed work stations such as hoods.
FFU’s are typically installed in two main configurations, the first of which draws air from a common plenum. One major advantage of a common plenum FFU system is that it inherently converts the ceiling plenum into a negative pressure space, thereby eliminating the risk of contaminants migrating from the ceiling plenum into the clean space below. The negative pressure is created as the FFU draws surrounding air from the common returns as well as fresh outside air from an AHU.
The FFU can be directly ducted from an AHU or terminal device.
