Vivosun AeroZesh G4 w/ E42A Smart Air Filtration Kit - 4" Duct

Struggling to maintain the perfect climate in your grow space? The VIVOSUN AeroZesh G4 Smart Air Filtration Kit delivers a complete, automated solution to manage your environment with precision. This all-in-one system combines a high-performance inline fan, an advanced WiFi controller, and professional-grade carbon filtration to take the guesswork out of cultivation.

At the heart of the kit is the AeroZesh G4, a 4-inch inline fan that moves an impressive 195 CFM of air while operating at a whisper-quiet 28 dB. Its mixed-flow design ensures powerful, consistent airflow, while the energy-efficient EC motor with PWM control significantly reduces power consumption compared to traditional AC fans. This makes it a core component of any modern inline fan system.

The included GrowHub E42A controller elevates your setup into a smart ecosystem. With dual sensors monitoring both internal and external conditions, it actively tracks temperature and humidity while calculating VPD (Vapor Pressure Deficit) for optimal plant health. You can program automated climate responses for every growth stage, adjusting fan speed and timing remotely through the VIVOSUN app, giving you complete control from anywhere.

FAQs

How does this system achieve such quiet operation at 28 dB?+

The VIVOSUN AeroZesh G4 uses an advanced mixed-flow impeller design combined with a brushless EC motor to achieve ultra-quiet operation. At 28 dB, it's quieter than a whisper and nearly silent in most environments, making it one of the quietest VIVOSUN air filtration kits available.

What size growing space is this kit best for?+

This 4-inch, 195 CFM system is optimized for small to medium growing spaces, such as 2'x2' to 4'x4' grow tents. Its mixed-flow design maintains effective air movement across the included 8-foot ducting without significant pressure loss, making it ideal for compact grow rooms.

How do I program automated responses with the controller?+

The GrowHub E42A controller connects to your WiFi and is programmed via the VIVOSUN app. You can create custom automation rules to increase fan speed when temperature or humidity exceeds a set threshold, adjust ventilation based on VPD, and set different day/night schedules. For a detailed guide on climate, check out this post on grow room temp and humidity.

Can I integrate other smart devices with this system?+

Yes, the GrowHub E42A platform allows you to connect and control multiple compatible VIVOSUN smart devices, including LED lights like the AeroLight Wing AW400, fans, and other environmental controls. This creates a unified smart grow system managed from a single app.

What regular maintenance does this kit require?+

Maintenance is minimal. We recommend cleaning the fan blades monthly, replacing the 4" carbon filter every 12-18 months depending on use, and wiping the controller's sensors quarterly. The brushless EC motor is maintenance-free.

What happens if my internet connection goes down?+

The system will continue to operate based on your last programmed settings even without an internet connection. All automation rules and sensor triggers will function locally on the controller. Once WiFi is restored, the system automatically reconnects for remote monitoring.
