Vivosun AeroZesh T4 w/ E42A Smart Air Filtration Kit - 4" Duct

The AeroZesh T4 uses an Electronically Commutated (EC) motor with PWM control, which is far more efficient than older AC motors. This technology can reduce power consumption by up to 50% while providing precise 0-100% speed control. EC motors also run cooler and have a longer lifespan with minimal maintenance.

This 4-inch, 210 CFM system is ideal for small to medium grow spaces, such as a 2'x2' grow tent up to a 4'x4' tent. Its mixed-flow design ensures effective air exchange even with up to 8 feet of ducting, making it a versatile choice for various setups.

Through the VIVOSUN mobile app, you can connect the GrowHub E42A to your WiFi and create custom automation rules. For example, you can set the fan to increase speed when the temperature exceeds a certain point or activate when humidity rises. For more details on ideal conditions, check out this guide to grow room temperature and humidity.

Yes, the GrowHub E42A platform is designed to unify your entire grow room. You can connect and control multiple compatible VIVOSUN smart devices, including lights and fans, creating a fully synchronized and automated ecosystem managed from a single app.

Maintenance is minimal. We recommend cleaning the fan blades occasionally and replacing the 4" carbon filter every 12-18 months, depending on use. The EC motor itself is brushless and virtually maintenance-free.

The AeroZesh T4 operates at just 39 dB, which is quieter than a typical household refrigerator. Its advanced motor and impeller design minimize noise without sacrificing its powerful 210 CFM airflow, ensuring a discreet and effective ventilation system.

The GrowHub controller will continue to operate based on the last settings you programmed, even if the WiFi connection drops. All automation rules are stored locally, so your environment remains stable. Once WiFi is restored, the system reconnects automatically.
