Description
Engineered for demanding ventilation setups, this EC mixed-flow inline duct fan kit combines high static pressure performance with ultra-quiet operation. The mixed-flow design helps maintain airflow through duct runs, bends, and filters, while the EC motor + PWM control ensures energy-efficient, stable performance across the entire speed range.
With an intelligent controller and integrated temperature/humidity monitoring, the fan can automatically ramp up or down to maintain your target environment—ideal for grow spaces, home ventilation projects, and equipment cooling.
Why You’ll Love It
1) Mixed-Flow Design = Stronger Pressure, Better Duct Performance

- Maintains steady airflow for more consistent ventilation results
2) EC Motor = Quiet, Efficient, Long-Lasting
- Lower energy consumption compared with traditional AC motors
- Runs smoother with reduced vibration for quieter operation
- Built for continuous-duty ventilation applications
3) PWM Stepless Speed Regulation
- Fine-tune airflow exactly to your needs
- Perfect for dialing in the balance between noise level and performance
- Stable, smooth RPM control across the range
4) Smart Temperature & Humidity Control (Automatic Mode)
- Integrated temperature & humidity sensors monitor the environment in real time
- Fan speed adjusts automatically to changing conditions
- Helps stabilize grow-room climate and improve overall air exchange efficiency
5) Clear Display + Simple Controls
- Real-time display of temperature, humidity, fan speed/RPM, and operating status
- Easy mode switching (e.g., ON/OFF, Timer, Auto—depending on your controller functions)
Ideal For
- Grow tent / grow room ventilation (hydroponics, indoor gardens, greenhouses)
