VIVOSUN AeroZesh Inline Fan – EC Mixed-Flow Extraction

Quiet EC extraction that only works as hard as your tent needs

The VivoSun AeroZesh S4 is a 4 inch mixed-flow inline duct fan built around an EC motor rather than a standard AC one, rated at 208 CFM (around 353 m3/h) and paired with the E12 controller for ten PWM-controlled speed steps. It suits growers who want real extraction without the constant drone of a fan stuck on one fixed speed.

Key Benefits

• 208 CFM (around 353 m3/h) airflow from an efficient EC motor, enough for compact and mid-size tents
• Ten PWM speed steps on the E12 controller to set the exact output your space needs at any time
• EC motor efficiency that draws less power and runs quieter than an equivalent AC fan
• Mixed-flow design for steady airflow through ducting and carbon filters
• 4 inch duct connection that drops straight into common tent ventilation setups

Fan either too loud or not shifting enough air?

A fixed-speed AC fan forces a choice between running flat out, which wastes energy and adds noise, or underpowering extraction and risking heat and humidity build-up. The EC motor and ten-step PWM controller let you set the AeroZesh S4 to the precise speed the tent needs, instead of picking between too much and not enough.

How to Use

• Fit the fan in-line with your ducting, drawing air toward the carbon filter and out of the tent
• Wire it to the E12 controller
• Start on a low speed and step up until temperature and humidity settle where you want them
• Adjust through the day as conditions change
