Customer Success Story — High-Efficiency Fan for FFU Cleanroom Applications

Key Takeaways

• 68 % total efficiency with spiral double-curved 5-blade impeller

• 2940 m³/h airflow at 300 Pa → optimized cleanroom pressure stability

• 10 % energy-efficiency improvement over prior design

• Compact 246 mm height for modular FFU systems

• Proven performance for semiconductor and pharmaceutical cleanrooms

Challenge — Energy Loss and Pressure Instability

The customer’s previous FFU fan could not maintain consistent airflow under varying filter resistance, leading to:

• Rising energy bills due to overcompensation

• Unstable differential pressure affecting cleanroom pass rates

• Frequent recalibration and downtime

AFL Solution — EC Mixed-Flow Centrifugal Design

AFL engineered a spiral double-curved 5-blade impeller to minimize resistance and turbulence.
Integrated EC motor technology delivered higher electrical-to-mechanical conversion efficiency while reducing thermal loss.

Performance Impact — Cleanroom Pass Rate +10 %

After integrating AFL fans, the customer reported:

• 10 % higher cleanroom pass rates

• Noticeable reduction in filter load variance

• Lower total cost of ownership within 12 months

• Improved end-user satisfaction for pharmaceutical validation audits

This quantifiable ROI reinforced AFL’s position as a strategic technology partner, not just a component vendor.

Continuous Innovation for FFU and Cleanroom OEMs

AFL’s in-house laboratory performs aerodynamic, acoustic, and endurance tests under cleanroom simulation.
Our ISO 9000 quality system and automated production ensure batch consistency and repeatable performance metrics—critical for global OEM compliance.
