VIVOSUN AeroZesh G8 8" Inline Exhaust Fan 725 CFM with E12 Cycle Speed Controller & Environmental Probe

The VIVOSUN G8 AeroZesh 8" inline fan is a high-flow, PWM-controlled EC exhaust fan with a programmable E12 cycle speed controller delivering up to 725 CFM for dependable grow-space ventilation.

The AeroZesh G8 combines strong mixed-flow airflow, a responsive PWM motor and a ten-step E12 controller to keep temperature and humidity more consistent in indoor gardens, tents and utility rooms. Designed for growers who need adjustable, quieter extraction without bulky wiring, this kit includes an environmental probe, long power cord and multiple control modes. It’s compatible with VIVOSUN’s GrowHub systems for future smart automation upgrades.

How does the G8 manage airflow and noise in tight spaces?

The AeroZesh G8 uses a mixed-flow impeller and an electronically commutated (EC) motor to produce efficient airflow with less turbulence. That design helps push up to 725 CFM while keeping sound levels lower than comparable axial fans at the same performance.

• Mixed-flow design for high static pressure and steady airflow
• EC motor controlled by PWM for smooth speed transitions
• Optimized impeller shape reduces turbulence and audible noise
• Compact 8" housing fits most tents and duct runs

What can I do with the E12 speed controller and cycle modes?

The included E12 controller offers ten selectable speed settings and three programmable ON/OFF cycle modes to alternate fan speeds automatically, helping conserve energy and create airflow patterns. It also retains the last speed after a power interruption, so you won’t have to reconfigure settings every restart.

• Ten discrete PWM-controlled speed levels for precise airflow
• Three cycle modes for scheduled speed alternation to save power
• Memory backup restores last-used speed after power loss
• Upgradeable to E42A or GrowHub for expanded automation

How does the environmental probe improve climate control?

An included probe measures ambient conditions and allows the fan to respond to changes in temperature and humidity by adjusting speed automatically. This makes the G8 useful as the central piece of an extraction system that balances climate without constant manual tuning.

• Probe feeds real-time data to the E12 controller
• Automatic speed adjustments maintain more consistent conditions
• Useful for stabilizing temperature and reducing humidity spikes
• Works standalone or as part of a larger GrowHub setup

The unit is ready for easy installation: a long power cord and hang-ready housing let you position the fan anywhere in a tent or room. If you outgrow manual control, the E12 can be replaced with VIVOSUN’s E42A or integrated with the app-enabled GrowHub system for remote scheduling and multi-device coordination.

Who is this for? The VIVOSUN G8 AeroZesh 8" inline fan is ideal for hobby and intermediate indoor growers, small commercial setups, and anyone needing a compact but powerful extraction solution. Choose it if you want fine-grained speed control, automatic climate-responsive operation, and upgrade paths to app-based automation without swapping your entire ventilation system.
