Choosing an AeroZesh Inline Fan
The right
VIVOSUN AeroZesh inline fan comes down to duct size (driven by tent footprint) and series tier (driven by whether you want manual or closed-loop control). The 4-inch AeroZesh covers 2x2 and 3x3 tents. The 6-inch is the most-used size, covering 3x3 through 5x5 tents at moderate duty cycles. The 8-inch is the right pick for 5x5 and larger or for builds with high-restriction filter setups.
AeroZesh Sizing
G vs S vs T Series
G-series is the budget tier: basic on-fan speed control via the E12 dial, no app integration. S-series adds onboard sensors for temperature and humidity, displaying live readings on the fan itself. T-series steps up to full UIS Smart Controller integration, so the fan ramps speed in response to a GrowHub controller's VPD targets. For most home grows, the T-series is the right long-term pick because the controller ecosystem expands as you add humidifiers, dehumidifiers, and lights to the same GrowHub.

Frequently Asked Questions
What size AeroZesh fan for a 4x4 tent?
A 6-inch AeroZesh T6 at roughly 400 CFM is the right size for a 4x4. Running at 50-60 percent duty cycle gives 1.5-2 air exchanges per minute through a carbon filter. Step up to the 8-inch T8 only if the build has high-power lighting (over 600W) or a long ducting run with high pressure drop.
AeroZesh G vs S vs T, what's the difference?
G-series has a basic on-fan speed dial with no sensors. S-series adds onboard temperature and humidity sensors with a live display on the fan itself. T-series ties into the GrowHub Smart Controller ecosystem for VPD-based closed-loop fan ramping. T-series is the upgrade pick for grows that will run multiple climate devices through one app.
Does the AeroZesh work with GrowHub?
T-series AeroZesh fans plug directly into a GrowHub Smart Controller via the UIS connector. G and S-series fans don't natively integrate; they run on their own onboard control. If you're building toward closed-loop climate automation, pick T-series from the start to avoid replacing the fan later.
How loud is the AeroZesh at full speed?
Roughly 45 dB on the 6-inch T6 at 100 percent. At the typical 50-60 percent duty cycle most grows run, the noise drops to 35-40 dB, which is quieter than a quiet refrigerator. The EC motor and sound-dampened housing are the reason the AeroZesh runs quieter than older AC-motor fans at equivalent airflow.
Can I daisy-chain two AeroZesh fans?
Yes through the GrowHub Smart Controller. The E42A has 4 output ports, so you can run two T-series AeroZesh fans on the same controller with synchronized scheduling. Native daisy-chain between the fans themselves (without a controller) isn't supported on G and S series.
What CFM does a 6" Cloudline produce?
For VIVOSUN's 6-inch AeroZesh T6, max airflow is roughly 400 CFM at 100 percent speed. After accounting for ducting and carbon filter pressure drop, real-world flow at the tent inlet drops to about 250-300 CFM, which is the right air-exchange rate for a 4x4 tent at moderate duty cycle.
