Fan Speed Controller for Precise Ventilation Control
The Active Air Duct Fan Speed Adjuster gives growers exact control over airflow, reducing noise and power draw while extending fan life. Designed specifically for centrifugal and inline fans, its sensitive electronics provide smooth, flicker-free adjustments that protect motors and stabilize your environment.
Built to Protect Your Equipment
An internal electronic auto-resetting breaker, state-of-the-art circuitry, and robust construction help prevent overload and premature wear. Rated for up to 500W (5A) at 100–120VAC, it’s ideal for most small to mid-size inline ventilation setups.
How It Helps Growers
By tuning fan RPM to the room’s needs, you’ll minimize temperature swings, reduce negative pressure, and cut unnecessary noise—key wins for grow room ventilation and HVAC efficiency. Pair it with carbon filters and ducting to fine-tune pressure and airflow through your system.
Uses & Compatibility
Best for ball-bearing inline/centrifugal fans used with ducting, filters, and air-cooled hoods. Not for booster fans or “squirrel cage” blowers. Compatible with Hydrofarm/Active Air inline fans and other brushless centrifugal models within the power rating.
