The SystemAir Revolution EC Vector is quite simply a cut above the competition.
An aerodynamically optimised impeller and special guide vanes give much larger air flows and greater performance when under pressure, whilst efficient German motors make these fans more powerful and efficient than any other fan in the same class.
Revolution EC Vector fans use 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 compared to AC motors. Over 50% more efficient than standard AC fans with no humming or buzzing at low speeds the compact and lightweight Revolution is easy to fit.  The most efficient powerful duct fans of their size, use with an EC Controller for complete grow room control.
More efficient, quieter and smaller than traditional duct fans, Revolution fans are an investment you can rely on!
