Systemair Revolution Vector EC Fan - 200mm (8") - 1332m3/hr

Vector fans feature frictionless electronically commutated (EC) motors that deliver a level of efficiency that blows the competition out of the water. They use around half the power of a tradtional duct fan, saving you piles of cash on your energy bills. They also generate huge pressure levels, moving a ridiculous volume of air for their size and dealing with the drag factor created by your carbon with ease. It should be noted that Vector fans need to be used in conjunction with a G.A.S. fan speed controller, which was designed and engineered specifically for use with EC motors. The results are tuly mindlowing: you can regulate fans with pinpoint acuracy, right down to 1% of their output in 1% increments, and with no buzzing or humming! Did you know that when you turn a typical duct fan down to, for instance, 50%, it will deliver less than 50% of its rated airflow and it will continue to use 100% of the power! That's because they were never designed to be regulated in the first place, making the process inefficient. Vector fans, however, were engineered specifically for the job. If you turn a Vector down to 1%, you'll get 1% of the max output and it will use around 1% of the power - a true feat of engineering!
