Description

The Tornado Pro EC Variable Speed Box Fan is built for growers who want precise control, strong airflow and improved energy efficiency. This fan fits either 10 or 12 inch ducting due to its innovative shapped stepped spigot.

The EC motor adjusts speed to your needs while keeping power use low. A lightweight yet tough body, integrated handles and switchable 10 inch and 12 inch flanges make this fan simple to set up in almost any layout.

With a running current of only 2.7A, the Tornado Pro delivers an impressive 4250 m3 per hour of airflow. EC technology keeps it smoother and quieter than traditional AC fans since dimming does not cause vibration or extra noise. The metal mounting brackets and low weight mean fast installation, while the durable housing ensures long service life.

This fan works with most EC controllers that use or can adapt to a 3.5 mm jack plug. You can run it manually through the calibrated speed settings including 2500 m3 per hour, 3250 m3 per hour, 4250 m3 per hour and a boost mode. The stepped flange accepts both 250 mm and 315 mm ducting. Use quality jubilee clips or fast clamps for a tight seal and keep ducting straight to minimise turbulence and noise.
