Key Features & Benefits

Manual 10-Speed Fan Controller 
Set and fine-tune your fan’s speed with precision using the included wired controller. Adjust airflow to match your environment’s needs, with memory backup to retain settings after power loss. Also compatible with UIS™ controllers for future smart upgrades.

EC Motor with PWM Technology 
Enjoy whisper-quiet operation and energy savings. The S12’s electronically commutated motor uses Pulse Width Modulation for smooth low-RPM performance with reduced heat and noise output.

Mixed-Flow Design for High Resistance
Built with stator blades and hydrodynamic wind circles, this fan moves air efficiently through carbon filters, ducting, and static pressure-heavy setups—ideal for serious ventilation challenges.
