Tornado Pro EC Box Fan 4250 M/3 Variable Speed (For 10″ or 12″ Duct)

Tornado Pro EC Box Fan 4250 m3 Variable Speed

The Tornado Pro EC Box Fan is built for powerful, controllable extraction in larger grow rooms and demanding ventilation setups. Its efficient EC motor delivers strong airflow while using less power than a traditional AC fan.

Ideal for controlled ventilation

Use the built-in speed selector for straightforward manual control, or connect a compatible EC controller to automate airflow according to temperature and humidity.

The Tornado Pro EC Box Fan is suited to growers who need high extraction performance but want more control over running costs, noise levels and airflow.

Installation

Mount the fan securely using the fitted metal brackets.

Connect ducting to either the 12 inch or 10 inch spigot and secure it with suitable duct clips.

Keep duct runs as straight as possible and avoid sharp bends to maintain efficient airflow.

Ducting, duct clips and EC controllers are sold separately.
