Engineered with an upgraded, high-efficiency motor configuration, the S4 delivers a powerful 205 CFM (348 m³\/h) of airflow while pulling an average of just 21 Watts.\u003c\/p\u003e\n\u003cp\u003ePowered by a digitally controlled PWM EC motor, the S4 operates at an ultra-quiet 28 dBA, making it virtually imperceptible in domestic environments. Its mixed-flow impeller, stator blades, and hydrodynamic wind circles build strong static pressure (223 Pa) to overcome resistance from carbon filters and tight duct bends. Equipped with a 10-speed digital controller and direct native UIS™ connectivity, the S4 plugs effortlessly into smart controllers like CONTROLLER 69 for full app-based automated climate control.\u003c\/p\u003e\n\u003ch3\u003eWhat Makes It Stand Out\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003eUltra-Quiet 28 dBA Performance:\u003c\/b\u003e PWM-controlled EC motor eliminates motor hum and electrical whine, operating smoothly across all 10 speed levels up to 2800 RPM.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eHigh-Output 205 CFM Airflow:\u003c\/b\u003e Provides rapid, continuous air exchange (348 m³\/h) for compact grow tents, micro-grows, and nursery setups.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eMixed-Flow High Static Pressure Design:\u003c\/b\u003e Stator blades and hydrodynamic wind circles force air through dense carbon filter beds and restrictive ducting.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003e10-Speed Digital Controller Included:\u003c\/b\u003e Fine-tune fan speed and noise levels with built-in memory that saves your speed setting during power interruptions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eNative UIS™ Ecosystem Connectivity:\u003c\/b\u003e Plugs directly into AC Infinity smart controllers for Wi-Fi\/Bluetooth app access, automated VPD triggers, and dynamic climate scheduling.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eDetachable Motor Box \u0026amp;
