Description
FFU (Fan Filter Unit)
FFU stands for Fan Filter Unit, which is a self-powered, modular terminal air supply device with filtration capabilities. The fan draws air from the top of the FFU, passes it through a HEPA filter, and delivers clean, filtered air uniformly across the entire air outlet surface at a velocity of 0.45 m/s ± 20%.
FFUs can be connected in a modular fashion, making them widely used in cleanrooms, clean benches, clean production lines, modular cleanrooms, and localized ISO Class 100 environments. FFU laminar flow hoods can also be used to create simple clean workstations, clean booths, pass boxes, and clean storage cabinets.
Features of FFU:
-
Multiple speed control options are available
-
Ultra-low operational power consumption, reducing energy costs, with microcomputer control
-
Built-in air duct and guide system to reduce noise and pressure loss, improving fan efficiency
-
Compatible with various high-efficiency filters such as HEPA and ULPA
-
Backward-curved centrifugal fan providing high airflow and high static pressure, with long service life
-
Suitable for cleanroom environments ranging from ISO Class 1 to Class 1000
-
Ideal for assembling ultra-clean production lines; can be used individually or connected in series for a Class 100 assembly line based on process requirements
-
Each unit is tested and scanned using a particle counter according to ISO 14644-1 standards before leaving the factory to ensure quality
After-sales Service:
