FAQs

How does the PWM-controlled EC motor improve efficiency?+

The AeroZesh G4 uses an advanced EC (Electronically Commutated) motor controlled by PWM (Pulse Width Modulation). This allows for precise speed adjustments, significantly reducing energy consumption to just 20 watts while maintaining powerful airflow and quiet operation compared to traditional AC motors.

What are the main benefits of the E12 controller?+

The E12 controller provides ten programmable fan speeds, three ON/OFF cycle modes for automation, and a backup memory that saves your settings during power outages. Its key feature is the environmental probe, which enables automatic fan speed adjustments based on real-time climate data.

How does the fan automatically respond to environmental changes?+

The included environmental probe continuously monitors temperature and humidity. The E12 controller then uses this data to automatically increase or decrease the fan's speed to maintain your target climate, ensuring a stable environment without constant manual adjustments. You can learn more about maintaining the perfect climate from our grow room temperature and humidity guide.

What size grow tent is the AeroZesh G4 suitable for?+

With 195 CFM of airflow, the AeroZesh G4 is ideal for effectively ventilating small to medium-sized grow tents, such as 2'x2', 2'x4', and 3'x3' models. It's a perfect ventilation solution for a setup like the VIVOSUN Smart Grow Tent Kit - 2 Plant G4.

How quiet is this fan during operation?+

The AeroZesh G4 operates at just 28 dB. The combination of the EC motor and steel construction minimizes noise and vibration, making it ideal for use in residential areas where quiet operation is essential.

Can I control the VIVOSUN AeroZesh G4 with my smartphone?+

Yes, the system is designed for easy upgrading. By connecting it to a VIVOSUN GrowHub controller like the E42A, you can unlock remote monitoring, scheduling, and full automation through the VIVOSUN App on your smartphone or tablet.
