Made by industry leader Systemair, the Revolution Vector 250L EC is the best duct fan on the hydroponics market. Built with an aerodynamically optimised impeller and special guide vanes to give much larger air flows than other fans of its size, even when under the usual pressures of a grow room environment. The Revolution Vector 250L EC uses the latest EC technology to bring power and efficiency together, using half the power when running at half the speed - unlike traditional AC motors.
Smaller and quieter than other fans - the Revolution Vector 250L EC is simply the most efficient duct fan in the world.
