FFU Fan Filter Units

Product Overview

Our FFU range enables flexible cleanroom ceiling design: each unit combines a high-efficiency EC motor, pre-filter, and HEPA/ULPA filter in a slim housing that drops into standard T-grid ceilings. Group control via RS-485 or 0–10V signal allows zone-based airflow management and significant energy savings.
