Latest company case about Guangzhou Cleanroom Construction Co., Ltd. Certifications

A Fan Filter Unit (FFU) is the core air filtration component in modern cleanroom systems. It combines a motorized fan and a HEPA filter into a single ceiling-mounted unit, delivering clean, filtered air directly into the cleanroom workspace below.

Our FFU is engineered for stable, uniform airflow with stepless speed control, ultra-low noise, and long-term reliability — tested individually to ISO 14644-1 before shipment.

What Is a Fan Filter Unit (FFU)?

A Fan Filter Unit draws air from the ceiling plenum, passes it through a HEPA filter rated at 99.99% efficiency @ 0.3μm, and delivers ultra-clean air into the cleanroom at a controlled, uniform velocity.

Multiple FFUs can be connected across a ceiling grid to form a complete laminar flow system, achieving Class 100 (ISO 5) cleanliness across large production areas. They are the preferred air filtration solution for pharmaceutical, semiconductor, medical device, and laboratory cleanrooms worldwide.
