The Revolution Vector EC is built by ventilation expert Systemair to be the most efficient duct fan available for the hydroponics market. The fan is built with an aerodynamically optimised impeller and special guide vanes to give much larger air flows and greater performance under the usual pressures of a grow room environment. 

Silenced EC Fan 6" & 10"

The Revolution Vector EC uses the latest state of the art EC technology. The brushless motors are more efficient than traditional motors and at half speed use less than half the power, unlike classic AC motors.
