    The unstoppable rise of Isomax Acoustic Fans has been one of the major success stories of recent years in the UK indoor gardening market. With a reassuringly robust design and high quality components, each of the four units will comfortably help you overcome the challenges of extracting air from a modern grow room. Key features include the innovative baffle and acoustic lined chamber (much like a very large silencer) that successfully combine to minimise overall noise output whilst allowing for movement of gargantuan amounts of air. Both of the two smaller fans also provide convenient inbuilt fan speed controllers, offering even more value for money! Very highly recommended! Learn More

    Trying to cut costs? Swap your RVK fan for an EC fan.

    EC fans are already much cheaper to run. On top of this, they use far less energy when slowed down by a fan speed controller.

    RVK fans aren’t as sophisticated when speed regulated. They always run at full power, even when dimmed down to just 1%.


    RVK Fan 200 A1
    • Max air flow: 800m3/h
    • Max power consumption: 104W


    Reduced to 10% on a controller: 104W

    Revolution Vector 160 EC
    • Max air flow: 806m3/h
    • Max power consumption: 77W

    Reduced to 10% on a controller: 7W

    Though EC fans cost more to buy, their running costs are so much lower that within about a year (dependent on fan size, speed and use) you’ll have made your money back. After that it’s save, save, save. And you’ll have a much better fan!
