Balanced Power for Mid-Size Grow Environments
Tailored for growers working with 3x3 or 4x4 grow tents, this 5-Inch EC Fan bundle delivers optimal airflow with low noise and power consumption. With greater static pressure than smaller fans, it can support longer ducting runs while maintaining consistent ventilation.

Smart Climate Automation Made Easy
The included EC Smart Controller features Auto, Manual, and Alarm modes, plus a thermal sensor probe that lets you automate fan speeds based on temperature. Set it once and maintain ideal growth conditions all day and night — no constant adjustments required.

Efficient Setup, Long-Term Performance
This bundle is plug-and-play ready, designed to save space, cut noise, and eliminate odor. Whether growing vegetables or flowering plants, it’s the next-level upgrade from 4-inch systems.

📦 Bundle Includes
5-Inch EC Inline Fan (Grow Cabinet Use)
5-Inch Carbon Filter – 400CFM Grow Odor Control
Smart EC Fan Controller with Thermal Probe

INSTALLATION ADVICEA detachable fast clamp is one of our recommended selected accessory for hard/PVC duct installation, which can be detached from the fan for easy cleaning, maintenance, and repair.
NOTE: ALL SIGILVENTUS EC FANS DO NOT FUNCTION WITHOUT SPEED CONTROL CONNECTION. SPEED CONTROL MUST BE CONNECTED BEFORE POWER UP.
