Fan Filter Unit (FFU)

A fan filter unit is a motorised unit which supplies clean, filtered air to a cleanroom. Air is drawn via the fan, through a pre-filter and then through a HEPA or ULPA filter which filters the sub-micron particles ensuring a clean and processed air supply. Using FFUs to provide localised clean air is a more energy efficient route than using a traditional Air Handling Unit (AHU) and is a more frequently adopted approach in modern cleanroom design.
