Vivosun Aerozesh S4 4″ Fan, Carbon Filter, Ducting + E42A Controller Kit

Introducing The AeroZesh S4 4” Inline Fan & Carbon Filter Kit

The AeroZesh S4 4” Inline Fan & Carbon Filter Kit with GrowHub E42A Controller is the ultimate solution for air circulation, ventilation, and odor control in grow tents, hydroponic systems, and indoor gardens. Designed for efficiency, precision, and quiet operation, this complete kit ensures your grow space stays stable, fresh, and fully optimized.

The AeroZesh S4 inline fan delivers a powerful 208 CFM airflow while operating at a whisper-quiet 39 dBA, thanks to its PWM-controlled mixed-flow design. This makes it perfect for moving air across long distances while keeping energy consumption low.

Paired with the GrowHub E42A Smart Controller, you gain advanced climate management with a built-in temperature and humidity gauge, plus VPD monitoring for precision growing. With WiFi connectivity and app control, you can track real-time data and remotely adjust your system anytime, anywhere.

To eliminate unwanted odors, the 4” carbon filter uses premium RC 412 Australian Virgin Charcoal with a 38mm thick, highly porous bed for maximum absorption. The included 8′ silver ducting is strong, flexible, and easy to install, with stainless steel clamps for a secure fit and rope hangers for hassle-free mounting.

This professional-grade kit combines quiet performance, intelligent control, and superior odor removal, making it an essential upgrade for serious growers.
