Vivosun AeroZesh S4 Air Filtration Kit - 4″ Duct

Struggling with stagnant air and unwanted odors in your grow space? The VIVOSUN AeroZesh S4 Air Filtration Kit provides a powerful, reliable, and straightforward solution to ensure your plants thrive in a clean, fresh environment. This complete air filtration kit is engineered for growers who demand high performance without the complexity of smart controllers, making it perfect for grow tents, hydroponic systems, and any indoor garden requiring consistent airflow.

At the heart of the kit is the AeroZesh S4 inline fan, which leverages a mixed-flow design and an advanced PWM-controlled EC motor to move an impressive 208 CFM of air. This technology ensures powerful ventilation over long ducting runs while consuming a mere 20W of power and operating at a whisper-quiet level below 45 dB. It's an ideal choice for maintaining optimal conditions in a 2'x2' grow tent or similar compact spaces.

Paired with the fan is a professional-grade carbon filter featuring 1200+ RC 412 Australian virgin charcoal, which effectively scrubs odors, smells, and particulates from the air. The durable, lightweight plastic construction makes installation a breeze, and with included ducting and clamps, you have everything you need to set up a high-efficiency ventilation system right out of the box. For growers who may want to add automation later, this system can be paired with an external controller or you can explore the AeroZesh S4 with E42A Smart Controller.

FAQs

What are the benefits of the mixed-flow fan design?+

The AeroZesh S4's mixed-flow design combines the high-pressure capabilities of a centrifugal fan with the high airflow rate of an axial fan. This results in a powerful 208 CFM airflow that remains strong even through long ducting runs, all while using less energy and operating more quietly (<45 dB) than traditional fan types.

What size grow space is this 4-inch kit suitable for?+

This 208 CFM system is ideal for small to medium grow tents, typically ranging from 2'x2' up to 4'x4'. It's designed to effectively ventilate spaces up to 104 cubic feet, ensuring complete air exchange to maintain an optimal environment. For more tips on managing your space, check out our guide to perfect climate control.

How do I control the fan speed?+

The AeroZesh S4 is a single-speed fan that runs at a constant 3000 RPM to provide a consistent 208 CFM airflow. This ensures reliable performance without complex setup. If you require variable speed, you can connect an external fan speed controller or consider upgrading to a smart VIVOSUN controller for full automation.

How often should the carbon filter be replaced?+

For optimal performance, we recommend replacing the carbon filter every 12 to 18 months, depending on the intensity of odors and the level of particulates in your environment. Regularly check the included pre-filter and wash it as needed to extend the life of the main carbon filter.

How energy-efficient is this kit?+

Extremely efficient. The fan's advanced PWM-controlled EC motor consumes only 20 watts of power while delivering 208 CFM. This is significantly more efficient than traditional AC-powered fans of a similar size, leading to lower energy costs and less heat output during continuous operation.
