The Revolution Stratos  AC is an energy efficient in-line fan with a 230V AC rotor motor, made by Systemair. Air flow is increasing using aerodynamically optimised impellers and guide vanes, meaning the Revolution Stratos AC range can handle typical air flow restrictions like carbon filters far better than any other duct fan. 

The Revolution Stratos 250 AC is smaller and quieter than traditional duct fans and custom built to perform in grow room environments.

The EC version, uses state of the art EC technology. More powerful and over 50% more efficient than standard AC fans. No humming or buzzing at low speeds. These fans are the most efficient powerful duct fans of their size. They can be precisely controlled with an EC Controller.

The AC version offers greater air flow and performance under pressure than any other AC fans on the market. They can be controlled by Triac, Step transformers or frequency controller.
