VIVOSUN G8 8" 725 CFM Inline Fan with E42A+ Smart Controller — EC Motor & App Control

The VIVOSUN G8 8" 725 CFM inline fan with its E42A+ smart controller is a compact, energy-efficient ventilation system that supplies powerful, automated airflow and climate monitoring for indoor growing spaces.

Built to pair robust mixed-flow airflow with app-driven automation, this G8 kit combines a PWM-controlled EC motor fan and a GrowHub-compatible controller to manage ventilation, track temperature and humidity, and automate responses based on preset grow stages. It’s designed for growers who want reliable air exchange, quieter operation, and hands-free climate management without juggling multiple standalone devices.

How does this fan improve ventilation in a grow tent or room?

The G8 produces up to 725 CFM of directed airflow through an efficient mixed-flow impeller, moving air long distances while maintaining pressure in ducted setups. Its EC motor reduces power draw compared with traditional AC fans, making consistent fresh-air exchange more affordable over time.

• 725 CFM maximum airflow for high-volume exchanges
• Mixed-flow design for stable, long-throw ventilation
• EC motor with PWM control for tighter speed regulation
• Mountable vertically or horizontally to fit tight spaces

What automation and monitoring features does the E42A+ controller provide?

The included E42A+ controller centralizes device management and environmental sensing: it logs temperature and humidity via a probe, calculates VPD values, and runs stage-based grow schedules. From the app you can apply recipes, set auto-triggers, and remotely change fan speeds and other device settings.

• Real-time temperature and humidity readouts plus VPD comparison
• Preset schedules for seedling, vegetative, and flowering stages
• Smart triggers to change fan behavior based on thresholds
• Wi‑Fi app access for remote monitoring and adjustments

How quiet and energy-efficient is the system for daily use?

The EC motor design delivers notable energy savings—typically around 30% less than conventional AC fans—while providing consistent speed control through PWM. Noise levels are reduced to comfortable operating volumes, allowing placement near living areas or compact grow rooms without excessive sound.

• EC motor for improved energy efficiency and longevity
• Operates as low as ~51 dB in quieter modes
• Precision PWM control avoids constant speed hunting and power spikes
• Reduced running costs compared to standard AC inline fans

Can this system integrate with other grow equipment and setups?

The G8 and E42A+ are built to be part of VIVOSUN’s integrated ecosystem, enabling coordinated control across growing devices. Whether you’re adding lights, controllers, or environmental accessories, the controller supports expandability and centralized recipe-based management.

• Works with other GrowHub-compatible devices and VIVOSUN ecosystem tools
• Supports ducted HVAC use, greenhouses, and hydroponic rooms
• Mountable in multiple orientations for flexible installs
• App recipes let you replicate successful environmental strategies

Who is this for? Growers who want a professional-feeling ventilation solution with automated climate control will benefit most: hobbyists scaling up from basic fans, small commercial cultivators seeking better consistency, and anyone wanting remote monitoring and stage-based schedules. If you need quieter operation, lower energy consumption, and a single app to orchestrate multiple devices, the VIVOSUN G8 with E42A+ controller gives a practical, modular path to more reliable indoor climate management.
