The Tornado Pro EC Box Fan 4250 m³/h delivers exceptional power, precision, and efficiency for serious growers and demanding industrial environments. Engineered with cutting-edge EC motor technology, this fan offers intelligent airflow control with dramatically reduced energy consumption — ensuring maximum performance with minimal running costs.

Built from durable yet lightweight materials, the Tornado Pro EC is easy to handle, install, and operate. Integrated handles and dual-spigot compatibility (10" and 12") provide unmatched flexibility for any setup, while its advanced motor system ensures silent, vibration-free operation. Whether you’re managing airflow in a large grow space or fine-tuning your extraction system, this fan sets the standard for reliability and control.

Reducers can be easily fitted to the Tornado Pro EC Fan’s 10–12" dual spigot, allowing quick adaptation to smaller ducting sizes such as 8". This makes the fan highly versatile and compatible with a wide range of ventilation systems.
