LENGE Fan Filter Units (FFU) are ceiling module diffusers consisting of HEPA-filter, fan and control system.

The module is designed to provide unidirectional vertical airflow of filtered, clean air over a cleanroom space by removing harmful airborne particles from recirculating air. FFU creates a positive room pressure that reduces the contamination risk from potential ceiling bypasses.

FFU models will have three stickers located on the back of the plenum. For ease of troubleshooting assistance, replacement parts, and general factory assistance, it is recommended that the order number, and model line string be used as reference. This information can be found on the Factory Label.
